For 7 00:00:21,520 --> 00:00:26,239 Speaker 1: our first episode, we're going with caterpillars colon Nature's Magicians 8 00:00:26,480 --> 00:00:28,520 Speaker 1: because we can't think of a more poetic way to 9 00:00:28,600 --> 00:00:32,240 Speaker 1: kick things off. So enjoy this episode, and enjoy the playlist, 10 00:00:32,479 --> 00:00:35,440 Speaker 1: and don't forget to think Spring with all your might. 11 00:00:37,240 --> 00:00:51,720 Speaker 2: Cool. Welcome to Stuff You Should Know, a production of iHeartRadio. 12 00:00:55,120 --> 00:00:57,720 Speaker 1: Hey, and welcome to the podcast. I'm Josh and there's 13 00:00:57,840 --> 00:01:00,480 Speaker 1: Chuck and there's Jerry. The three of us just inchin 14 00:01:00,560 --> 00:01:04,360 Speaker 1: along in life together, trying to make do, making our 15 00:01:04,400 --> 00:01:07,199 Speaker 1: way in the world today. It takes everything a cop 16 00:01:09,560 --> 00:01:11,120 Speaker 1: Oh yeah, and this is stuff you should. 17 00:01:12,720 --> 00:01:13,080 Speaker 2: Cheers. 18 00:01:13,760 --> 00:01:16,520 Speaker 1: Cheers, Chuck cheers. Uh. 19 00:01:17,200 --> 00:01:22,520 Speaker 3: You know, if it's an episode where we say mouth parts. 20 00:01:22,240 --> 00:01:23,400 Speaker 1: I knew you're gonna say. 21 00:01:23,200 --> 00:01:27,160 Speaker 3: This, then we're going back to the old school from 22 00:01:27,240 --> 00:01:31,360 Speaker 3: our let's say, former colleague Tracy is still our colleague. 23 00:01:31,400 --> 00:01:34,120 Speaker 2: We just never see anyone anymore, right fully. 24 00:01:34,319 --> 00:01:38,400 Speaker 3: But Tracy Wilson, a co host of The Stuff You 25 00:01:38,440 --> 00:01:41,360 Speaker 3: Missed in History Class along with Holly. They're wonderful. They've 26 00:01:41,360 --> 00:01:46,200 Speaker 3: been around for years. They're icons of podcasting. Tracy used 27 00:01:46,240 --> 00:01:48,760 Speaker 3: to write a bunch of insect articles for HowStuffWorks dot 28 00:01:48,760 --> 00:01:49,560 Speaker 3: com back in the day. 29 00:01:49,720 --> 00:01:53,320 Speaker 1: She very legendarily stayed up for seventy two straight hours 30 00:01:53,320 --> 00:01:56,160 Speaker 1: and wrote like more than two dozen insect articles in 31 00:01:56,200 --> 00:01:59,600 Speaker 1: that time. They just got weirder and as the time 32 00:01:59,640 --> 00:01:59,920 Speaker 1: went on. 33 00:02:00,320 --> 00:02:04,440 Speaker 3: I almost believe that for a second. But Tracy always 34 00:02:04,440 --> 00:02:06,480 Speaker 3: does a great job with those, or did a great job, 35 00:02:06,600 --> 00:02:10,680 Speaker 3: And most of most of the insect articles we've ever 36 00:02:10,800 --> 00:02:14,920 Speaker 3: used have been Tracy's original, like the ticks and the 37 00:02:14,960 --> 00:02:20,040 Speaker 3: fleas and I don't think ants, but bees probably was. 38 00:02:20,680 --> 00:02:22,440 Speaker 1: She's the master of it for sure. 39 00:02:23,000 --> 00:02:25,160 Speaker 3: I mean she wrote a lot of them, and this 40 00:02:25,200 --> 00:02:28,560 Speaker 3: one about caterpillars was from Tracy, along with stuff from 41 00:02:28,680 --> 00:02:31,200 Speaker 3: World at List in the eighty eight and rereading butterflies 42 00:02:31,240 --> 00:02:34,080 Speaker 3: dot com. But I just realized today when I was 43 00:02:34,120 --> 00:02:37,920 Speaker 3: researching this some more, that we haven't done butterflies yet no, 44 00:02:38,040 --> 00:02:39,320 Speaker 3: which is shocking. 45 00:02:39,919 --> 00:02:41,720 Speaker 1: We've done one we. 46 00:02:41,639 --> 00:02:43,880 Speaker 2: Did the wings like that, you're desk Okay. 47 00:02:43,680 --> 00:02:45,320 Speaker 1: That's what it was. Yeah, And we talked about them 48 00:02:45,360 --> 00:02:47,200 Speaker 1: in the Animal Migration episode two. 49 00:02:47,800 --> 00:02:50,400 Speaker 3: Yeah, but not a standalone on butterflies. So we're going 50 00:02:50,480 --> 00:02:55,000 Speaker 3: to talk about their their counterpart. And one of the 51 00:02:55,000 --> 00:02:57,920 Speaker 3: facts of the episode already for me is that but 52 00:02:58,200 --> 00:03:00,600 Speaker 3: caterpillars that eventually turned into butterflies. 53 00:03:01,040 --> 00:03:03,359 Speaker 2: It's it's the same species. It's still the same thing. 54 00:03:03,560 --> 00:03:03,760 Speaker 4: Right. 55 00:03:04,320 --> 00:03:06,200 Speaker 1: We should never knew that we should do it too, 56 00:03:06,800 --> 00:03:07,200 Speaker 1: You didn't. 57 00:03:08,120 --> 00:03:10,880 Speaker 2: I just figured it like, well, now it's something else, 58 00:03:11,080 --> 00:03:12,519 Speaker 2: like entirely huh. 59 00:03:12,560 --> 00:03:15,600 Speaker 1: But did you know about the transformation and the chrysalis 60 00:03:15,639 --> 00:03:17,800 Speaker 1: or cocoon and everything? Did you know that was sure? 61 00:03:17,919 --> 00:03:19,680 Speaker 3: Okay, I knew how it happened, but I thought it 62 00:03:19,720 --> 00:03:24,440 Speaker 3: was like presto chaninjo. Now you're you're not whatever Latin 63 00:03:24,480 --> 00:03:26,000 Speaker 3: name you are, you're a new Latin name. 64 00:03:26,040 --> 00:03:28,560 Speaker 1: Oh gotcha. So like they just became a completely different 65 00:03:28,760 --> 00:03:32,720 Speaker 1: animal basically, or a different insect. Yeah, okay, I gotcha. Yeah, No, 66 00:03:32,760 --> 00:03:36,040 Speaker 1: they're the same thing, they're just configured differently. Yeah, they 67 00:03:36,120 --> 00:03:39,160 Speaker 1: got wings like a transformer, like they go box to 68 00:03:39,520 --> 00:03:42,840 Speaker 1: robot with the gun. That's right, you know, But in 69 00:03:42,880 --> 00:03:46,160 Speaker 1: a much more organic, soupy way, as we'll see you. 70 00:03:46,760 --> 00:03:49,480 Speaker 1: I love this one, Chuck. Like every kid knows about 71 00:03:49,520 --> 00:03:51,680 Speaker 1: caterpillars to go look at them in the garden and everything, 72 00:03:51,680 --> 00:03:54,280 Speaker 1: and they're super cute and weird looking, and you learn 73 00:03:54,320 --> 00:03:57,280 Speaker 1: the hard way not to touch some of them. But 74 00:03:57,800 --> 00:04:00,320 Speaker 1: I did not know a lot of this stuff either, 75 00:04:00,440 --> 00:04:03,760 Speaker 1: and it's endlessly fascinating to me, especially if you step 76 00:04:03,760 --> 00:04:08,560 Speaker 1: back and think about a life stage where an organism 77 00:04:08,920 --> 00:04:13,200 Speaker 1: undergoes such a complete transformation that their cells, they break 78 00:04:13,240 --> 00:04:17,240 Speaker 1: themselves down to their cells and then are rebuilt into 79 00:04:17,279 --> 00:04:20,720 Speaker 1: a new version. Not that many animals do that, and 80 00:04:21,120 --> 00:04:24,960 Speaker 1: scientists aren't exactly sure how or even why that evolved. 81 00:04:25,000 --> 00:04:28,120 Speaker 1: Although why it's kind of teleological, but how that evolved. 82 00:04:29,839 --> 00:04:33,279 Speaker 1: It's just this really bizarre thing that we're so aware of, 83 00:04:33,360 --> 00:04:35,360 Speaker 1: we kind of just take for granted until you really 84 00:04:35,360 --> 00:04:38,680 Speaker 1: stop and think about it. I love caterpillars, I guess, 85 00:04:38,760 --> 00:04:39,800 Speaker 1: is what I'm trying to say. 86 00:04:40,360 --> 00:04:43,000 Speaker 3: Yeah, And it was also one of those where I 87 00:04:43,080 --> 00:04:44,880 Speaker 3: just I kept looking and kept looking. I was like, 88 00:04:44,880 --> 00:04:47,120 Speaker 3: how has just this been sitting here under our noses 89 00:04:47,200 --> 00:04:50,080 Speaker 3: all this time? I don't know, because it's right up 90 00:04:50,080 --> 00:04:52,000 Speaker 3: our Alley to talk about something like cat. 91 00:04:53,880 --> 00:04:53,920 Speaker 2: No. 92 00:04:54,400 --> 00:04:58,279 Speaker 1: Yeah. One of the reasons why they are so different 93 00:04:58,520 --> 00:05:02,800 Speaker 1: and they're configured differently, is that a caterpillar's life it 94 00:05:03,240 --> 00:05:06,600 Speaker 1: is the larval stage of an adult moth or butterfly. 95 00:05:06,720 --> 00:05:11,600 Speaker 1: That's probably the best easy definition of a caterpillar. The 96 00:05:12,120 --> 00:05:15,159 Speaker 1: reason that it's configured differently than its adult form is 97 00:05:15,200 --> 00:05:21,640 Speaker 1: because in the larval stage, its entire life is pooping, eating, pooping, molting, eating, 98 00:05:21,720 --> 00:05:25,480 Speaker 1: pooping molting. That's what I saw the caterpillar's life described 99 00:05:25,520 --> 00:05:28,360 Speaker 1: as over the course of five different molts. As we'll see, 100 00:05:28,640 --> 00:05:30,200 Speaker 1: that's all it does. That's all it wants to do. 101 00:05:30,279 --> 00:05:33,480 Speaker 1: It just wants to eat. So it's designed essentially as 102 00:05:33,480 --> 00:05:34,440 Speaker 1: an eating machine. 103 00:05:34,920 --> 00:05:37,880 Speaker 3: Yeah, kind of shark like. And as Tracy points out, 104 00:05:37,920 --> 00:05:41,960 Speaker 3: like it's a very singular purpose. And the same butterfly 105 00:05:42,040 --> 00:05:45,680 Speaker 3: has a singular purpose later on, which is propagating the species, 106 00:05:46,640 --> 00:05:49,520 Speaker 3: if you know what I'm saying. But the caterpillar, yeah, 107 00:05:49,520 --> 00:05:50,200 Speaker 3: it's very shark like. 108 00:05:50,200 --> 00:05:51,240 Speaker 2: All it does is eat. 109 00:05:51,480 --> 00:05:54,839 Speaker 3: And store food and poop it out. And they eat 110 00:05:54,920 --> 00:05:57,840 Speaker 3: so much that apparently they say that they can eat 111 00:05:57,839 --> 00:06:00,919 Speaker 3: as much as twenty seven times they're body size in 112 00:06:01,000 --> 00:06:04,280 Speaker 3: their fairly short life. Yeah, and they can end up 113 00:06:04,279 --> 00:06:08,359 Speaker 3: being about one hundred times bigger at the by the 114 00:06:08,360 --> 00:06:10,520 Speaker 3: time they go to pupe et, which is when they 115 00:06:10,560 --> 00:06:12,800 Speaker 3: you know, hole up and turn into the butterfly as 116 00:06:12,839 --> 00:06:13,400 Speaker 3: when they. 117 00:06:13,279 --> 00:06:15,960 Speaker 2: Pop out of that little egg that they also eat. 118 00:06:16,120 --> 00:06:19,920 Speaker 1: That's amazing. And if you want to see something just astounding, 119 00:06:20,120 --> 00:06:24,359 Speaker 1: go look up a caterpillar egg or butterfly egg. I 120 00:06:24,360 --> 00:06:26,280 Speaker 1: don't know which one you'd call it, but they look 121 00:06:26,360 --> 00:06:30,480 Speaker 1: like little have you ever seen vasaline glass Huh? They 122 00:06:30,560 --> 00:06:33,799 Speaker 1: look like little like ornate vasaline glass vases. 123 00:06:34,320 --> 00:06:35,400 Speaker 2: Yeah, they're very pretty. 124 00:06:35,560 --> 00:06:39,279 Speaker 1: Yeah, I mean everything about butterflies are just great. Okay, 125 00:06:39,360 --> 00:06:40,920 Speaker 1: I'm on board with them fully. 126 00:06:42,520 --> 00:06:45,440 Speaker 3: But yeah, that thing, I mean, it starts eating, It 127 00:06:45,480 --> 00:06:46,720 Speaker 3: eats its way out of the egg. 128 00:06:47,200 --> 00:06:49,800 Speaker 2: Then it says, well, I'll just eat the rest of 129 00:06:49,839 --> 00:06:50,440 Speaker 2: the egg. 130 00:06:50,960 --> 00:06:54,040 Speaker 3: And you know, I'm gonna I'm gonna go ahead and 131 00:06:54,080 --> 00:06:56,520 Speaker 3: eat this leaf that the egg is sitting on as well. 132 00:06:56,360 --> 00:06:57,000 Speaker 2: While I'm at it. 133 00:06:57,160 --> 00:06:57,480 Speaker 1: Uh huh. 134 00:06:57,920 --> 00:07:00,080 Speaker 3: And they said, wow, I really like eating. Maybe I 135 00:07:00,120 --> 00:07:02,120 Speaker 3: should just keep eating for the rest of my life. 136 00:07:02,279 --> 00:07:05,400 Speaker 1: Yeah, each one suddenly turns into Augustus glop and just 137 00:07:05,480 --> 00:07:06,560 Speaker 1: keeps going from there. 138 00:07:07,120 --> 00:07:08,080 Speaker 2: That's exactly right. 139 00:07:08,320 --> 00:07:11,240 Speaker 1: So I said that at molts. Apparently it molts five 140 00:07:11,320 --> 00:07:14,720 Speaker 1: different times, and the reason why it molts is because 141 00:07:14,720 --> 00:07:16,800 Speaker 1: it eats so much it outgrows its skin. 142 00:07:17,480 --> 00:07:18,240 Speaker 2: It's amazing. 143 00:07:18,600 --> 00:07:21,440 Speaker 1: It has a mechanism where it releases an enzyme. There's 144 00:07:21,440 --> 00:07:23,880 Speaker 1: a hormone that says, hey, you're getting a little your 145 00:07:24,080 --> 00:07:26,200 Speaker 1: clothes are getting a little tight. Maybe it's time to bolt. 146 00:07:26,560 --> 00:07:30,080 Speaker 1: And so that releases an enzyme that basically dissolves its 147 00:07:30,120 --> 00:07:34,520 Speaker 1: attachment to the exoskeleton. And then the new, bigger version 148 00:07:34,920 --> 00:07:38,520 Speaker 1: pops out of the old exoskeleton, walks away, and guess 149 00:07:38,520 --> 00:07:41,679 Speaker 1: what it does immediately after it starts eating again. 150 00:07:41,800 --> 00:07:44,000 Speaker 2: Yeah, it tries to outgrow that suit. 151 00:07:44,920 --> 00:07:47,440 Speaker 1: And it does that five times in its larval stage 152 00:07:47,480 --> 00:07:48,360 Speaker 1: as a caterpillar. 153 00:07:48,880 --> 00:07:51,360 Speaker 2: Yeah, these molts are called in stars. Did you say. 154 00:07:51,160 --> 00:07:55,400 Speaker 1: That that's the period of its life between molts. 155 00:07:55,800 --> 00:07:59,600 Speaker 3: Yeah, yeah, so five in stars and between molts. Like 156 00:07:59,640 --> 00:08:01,760 Speaker 3: you said, all it's doing is just eating, trying to 157 00:08:01,760 --> 00:08:06,240 Speaker 3: get a larger suit size. But here's another cool fact 158 00:08:06,480 --> 00:08:11,000 Speaker 3: is they believe that not only do caterpillars have a 159 00:08:11,040 --> 00:08:15,480 Speaker 3: memory that lasts like a molt or two, but they 160 00:08:15,520 --> 00:08:20,040 Speaker 3: even think there are researchers at Georgetown that have sort 161 00:08:20,080 --> 00:08:22,840 Speaker 3: of proven that. I'm not how you sort of prove something, 162 00:08:23,360 --> 00:08:25,240 Speaker 3: but they feel pretty good about the fact that they 163 00:08:25,240 --> 00:08:28,920 Speaker 3: think that a butterfly remembers being a caterpillar. 164 00:08:29,240 --> 00:08:31,880 Speaker 1: Yeah, they've done this at least one study that showed 165 00:08:31,880 --> 00:08:35,000 Speaker 1: that if they trained it to avoid certain smells as 166 00:08:35,240 --> 00:08:39,400 Speaker 1: one of its last in stars, it will remember that 167 00:08:39,480 --> 00:08:42,800 Speaker 1: as an adult butterfly, that it will avoid those same smells. 168 00:08:43,200 --> 00:08:46,640 Speaker 1: That's pretty cool because, as you'll see, what happens in 169 00:08:46,679 --> 00:08:50,520 Speaker 1: the chrysalis is so mind bending and nuts that the 170 00:08:50,600 --> 00:08:55,040 Speaker 1: idea that it can remember anything is it's pretty pretty amazing. 171 00:08:55,679 --> 00:08:57,839 Speaker 3: Oh yeah, for sure, I didn't even consider that. That 172 00:08:58,360 --> 00:08:59,920 Speaker 3: is really hard to process. 173 00:09:00,559 --> 00:09:03,440 Speaker 1: So let's talk about the body. Like you said, it 174 00:09:03,480 --> 00:09:07,960 Speaker 1: has mouth parts very important because it eats, eats, eats, 175 00:09:08,840 --> 00:09:12,280 Speaker 1: and the rest of its body is essentially a storage 176 00:09:12,320 --> 00:09:16,720 Speaker 1: facility for that food that it eats and that it 177 00:09:16,760 --> 00:09:20,199 Speaker 1: breaks down and stores. Essentially is fat. They're very fatty. 178 00:09:21,040 --> 00:09:21,280 Speaker 2: Yeah. 179 00:09:21,360 --> 00:09:25,640 Speaker 3: I get the idea that the inner body movement through 180 00:09:25,679 --> 00:09:30,320 Speaker 3: that body tube never stops. It's just a conveyor belt 181 00:09:30,360 --> 00:09:33,199 Speaker 3: almost of food coming in and poop leaving. 182 00:09:33,679 --> 00:09:35,680 Speaker 1: That's my impression too. 183 00:09:36,320 --> 00:09:41,480 Speaker 3: Yeah, the caterpillar is six legged. If you're like Pho Chuck. 184 00:09:41,800 --> 00:09:44,600 Speaker 3: I've seen a caterpillar or two in my day, and 185 00:09:44,640 --> 00:09:46,360 Speaker 3: they have tons of little legs. 186 00:09:47,160 --> 00:09:48,920 Speaker 2: Those are not real legs. 187 00:09:48,960 --> 00:09:52,480 Speaker 3: They only have six genuine legs, meaning that they have 188 00:09:52,920 --> 00:09:56,200 Speaker 3: segments and joints. The rest of those are called pro legs, 189 00:09:56,840 --> 00:09:58,840 Speaker 3: and there are a lot of those, and they move 190 00:09:58,840 --> 00:10:01,880 Speaker 3: all up the length of the abdomened the caterpillar, and 191 00:10:02,000 --> 00:10:03,520 Speaker 3: at the end of those little pro legs they have 192 00:10:03,600 --> 00:10:07,600 Speaker 3: little suction cups, little hooks. Basically, is it is it 193 00:10:07,600 --> 00:10:09,680 Speaker 3: a crochette? Do you think I think crochet? 194 00:10:09,880 --> 00:10:10,760 Speaker 1: I'm going with crochet. 195 00:10:11,360 --> 00:10:17,120 Speaker 2: Yeah, they're called crouschettes. And the yachts a crack rocket. 196 00:10:18,920 --> 00:10:22,480 Speaker 3: Isn't that what those really fast motorcycles are called. Sure, okay, 197 00:10:23,200 --> 00:10:25,360 Speaker 3: I didn't know if that was, you know, a dirty 198 00:10:25,360 --> 00:10:26,040 Speaker 3: thing to say or not. 199 00:10:26,360 --> 00:10:29,559 Speaker 1: No, no, that's all over. It's like douchebag. It was 200 00:10:29,640 --> 00:10:32,960 Speaker 1: it one time, like not very nice, but now everybody 201 00:10:32,960 --> 00:10:35,920 Speaker 1: says it, so even PG. Thirteen Movies. 202 00:10:36,640 --> 00:10:38,760 Speaker 3: Oh I thought you meant it was okay to say, yes, 203 00:10:38,840 --> 00:10:39,640 Speaker 3: you're a real douchebag. 204 00:10:39,760 --> 00:10:42,920 Speaker 1: Okay, Oh no, no, no, it's not. Still not, but 205 00:10:42,960 --> 00:10:45,520 Speaker 1: it's not like, you know, a horrid thing to say 206 00:10:45,559 --> 00:10:46,200 Speaker 1: like it used to. 207 00:10:46,760 --> 00:10:48,480 Speaker 3: I gotcha because someone called me one the other day 208 00:10:48,480 --> 00:10:49,800 Speaker 3: in the car and I was like, oh, I thank you. 209 00:10:49,960 --> 00:10:56,440 Speaker 2: Did they really No? No, they don't have bones, of course, 210 00:10:56,480 --> 00:10:58,480 Speaker 2: but they do have lots. They're very muscly. 211 00:10:59,240 --> 00:11:01,640 Speaker 3: If you compare them to a human, we have about 212 00:11:01,960 --> 00:11:05,600 Speaker 3: six hundred and twenty nine muscles. Caterpillars have four thousand muscles. 213 00:11:06,240 --> 00:11:09,360 Speaker 3: Because those muscles, that's the way they're moving, you know. 214 00:11:09,400 --> 00:11:12,840 Speaker 3: They move in a little wave from front to back, 215 00:11:13,320 --> 00:11:15,679 Speaker 3: front to back. Yes, front to back, back to front, 216 00:11:16,240 --> 00:11:18,240 Speaker 3: back to front. How did I mess that up? 217 00:11:18,440 --> 00:11:20,160 Speaker 1: Well, it depends on which the direction they're going. 218 00:11:20,200 --> 00:11:23,079 Speaker 3: I guess, well, I guess so, And they move in 219 00:11:23,480 --> 00:11:25,360 Speaker 3: a couple of ways. One of two ways is sometimes 220 00:11:25,400 --> 00:11:28,199 Speaker 3: they're crawling, which means they're moving all of those pro 221 00:11:28,280 --> 00:11:32,000 Speaker 3: legs and legs at the same time in sequence. Or 222 00:11:32,320 --> 00:11:34,600 Speaker 3: they do what it sounds like an inch worm does. 223 00:11:34,679 --> 00:11:34,920 Speaker 2: Right. 224 00:11:35,200 --> 00:11:38,640 Speaker 1: Yeah, I don't know why they didn't identify them as inchorms, 225 00:11:38,640 --> 00:11:40,599 Speaker 1: but that's what they're talking about. They can move in 226 00:11:40,640 --> 00:11:44,600 Speaker 1: little arches where they bring their their front to their 227 00:11:44,679 --> 00:11:47,719 Speaker 1: back and their back together, making a mound. Out of 228 00:11:47,760 --> 00:11:50,320 Speaker 1: their middle their abdomen, and then they stretch the front 229 00:11:50,320 --> 00:11:51,840 Speaker 1: out and they bring the back up and then they 230 00:11:51,840 --> 00:11:53,760 Speaker 1: stretch the front up. That's what an inch worm does. 231 00:11:53,840 --> 00:11:56,600 Speaker 1: And that's basically one of two ways. The other way 232 00:11:57,000 --> 00:12:00,000 Speaker 1: for a caterpillar to move, either as a wave under. 233 00:12:01,040 --> 00:12:03,400 Speaker 1: There's a lot of like really cool videos of caterpillars 234 00:12:03,440 --> 00:12:05,040 Speaker 1: moving or inching along. 235 00:12:05,920 --> 00:12:08,720 Speaker 3: Yeah, and I never looked close enough at an inch 236 00:12:08,800 --> 00:12:12,640 Speaker 3: worm to figure out why they move that way. And 237 00:12:12,679 --> 00:12:15,160 Speaker 3: I feel like a dummy now because it seems obvious 238 00:12:15,559 --> 00:12:18,800 Speaker 3: they move that way because their middle section doesn't have legs, right, 239 00:12:19,200 --> 00:12:21,880 Speaker 3: it's pretty The front pulls the back because those are 240 00:12:21,880 --> 00:12:23,439 Speaker 3: where the legs are, and the legs go, let me 241 00:12:23,480 --> 00:12:23,920 Speaker 3: catch up. 242 00:12:24,040 --> 00:12:25,400 Speaker 2: It's like a little cute accordion. 243 00:12:25,559 --> 00:12:28,160 Speaker 1: And it's really neat to see. When you watch a 244 00:12:28,200 --> 00:12:31,520 Speaker 1: close up of a centipeder, I keep wanting to say centipede, 245 00:12:31,520 --> 00:12:35,920 Speaker 1: but that's definitely a different animal. Caterpillars pro legs moving 246 00:12:36,840 --> 00:12:39,640 Speaker 1: as they they attach themselves. Like you said, they have 247 00:12:39,640 --> 00:12:42,480 Speaker 1: a suction cup. They just attach themselves to like the 248 00:12:42,679 --> 00:12:45,960 Speaker 1: branch or whatever that they're walking on. And if you 249 00:12:46,200 --> 00:12:53,040 Speaker 1: watch it and close enough detail, yes, excellent, Chuck, you 250 00:12:53,080 --> 00:12:55,760 Speaker 1: can really see those suction cups working and it's pretty cool. 251 00:12:56,320 --> 00:12:56,920 Speaker 2: It's awesome. 252 00:12:57,880 --> 00:13:01,120 Speaker 3: Most things on a caterpillar are small, obviouslycluding their little eyelets. 253 00:13:01,679 --> 00:13:05,000 Speaker 3: They have twelve of those are called stemata, and they 254 00:13:05,120 --> 00:13:07,000 Speaker 3: if you do look closely, though, it's really cool looking. 255 00:13:07,080 --> 00:13:10,719 Speaker 3: They have their arrange in a semi circle, sort of 256 00:13:10,800 --> 00:13:12,360 Speaker 3: wrapping around the head. 257 00:13:12,640 --> 00:13:15,720 Speaker 1: Like what's his name from Reading Rainbow but on Star 258 00:13:15,800 --> 00:13:17,280 Speaker 1: Trek the next generation. 259 00:13:18,040 --> 00:13:18,880 Speaker 2: Yeah, LeVar Burton. 260 00:13:19,600 --> 00:13:23,040 Speaker 3: Like his eyewear, Yes, yeah, that's what I said. It 261 00:13:23,040 --> 00:13:24,920 Speaker 3: would be on top of his head though, right, like 262 00:13:24,920 --> 00:13:27,800 Speaker 3: like a headband. I think is it more on the front? 263 00:13:27,840 --> 00:13:28,720 Speaker 3: I thought it was more on top. 264 00:13:29,160 --> 00:13:30,840 Speaker 1: I thought it was on the front, but you could 265 00:13:30,840 --> 00:13:32,000 Speaker 1: be right, it could be on top. 266 00:13:32,600 --> 00:13:34,680 Speaker 2: It's kind of hard to tell with the caterpillar head 267 00:13:34,840 --> 00:13:35,520 Speaker 2: right exactly. 268 00:13:35,679 --> 00:13:37,800 Speaker 1: You don't really know what's what. It's kind of like 269 00:13:37,800 --> 00:13:39,920 Speaker 1: a studio baker. You can't tell which way it's going, 270 00:13:40,400 --> 00:13:47,200 Speaker 1: right for our aged listeners love a good STUDI baker, Joe. 271 00:13:47,440 --> 00:13:50,000 Speaker 2: Yeah, there's one little guys like Damn Skippy. 272 00:13:51,520 --> 00:13:54,880 Speaker 3: Uh So those stamata they can identify light in darkness, 273 00:13:54,880 --> 00:13:59,120 Speaker 3: but caterpillars are are basically blind. They're for sure color blind, 274 00:14:00,040 --> 00:14:01,559 Speaker 3: and they just like I said, they can see sort 275 00:14:01,559 --> 00:14:03,400 Speaker 3: of light and dark and shadow and stuff like that, 276 00:14:03,880 --> 00:14:07,880 Speaker 3: but they are not like they're not crawling around seeing things. 277 00:14:07,880 --> 00:14:10,439 Speaker 3: They're kind of feeling their way around with those antennae 278 00:14:10,440 --> 00:14:14,600 Speaker 3: that they have. But although those antennae only handle taste 279 00:14:14,600 --> 00:14:16,320 Speaker 3: and smell, so I don't even know why I said that. 280 00:14:16,800 --> 00:14:19,760 Speaker 1: So they also breathe in a really interesting way. They 281 00:14:19,760 --> 00:14:22,360 Speaker 1: breathe through spiracles, which are holes in the side of 282 00:14:22,400 --> 00:14:26,120 Speaker 1: the caterpillar, and they breathe in oxygen. It goes directly 283 00:14:26,120 --> 00:14:29,320 Speaker 1: to the trachea, and they breathe out carbon dioxide and 284 00:14:29,440 --> 00:14:32,600 Speaker 1: as they move, it's kind of like breathing in and 285 00:14:32,640 --> 00:14:36,280 Speaker 1: breathing out. That's like a byproduct of their movement, and 286 00:14:36,320 --> 00:14:38,040 Speaker 1: it all goes to that trichia, like I said, and 287 00:14:38,080 --> 00:14:41,960 Speaker 1: the trachia just diffuses it to the tissue throughout the body. 288 00:14:42,280 --> 00:14:45,440 Speaker 1: They have blood. It's called hemolymph like most insects blood, 289 00:14:45,560 --> 00:14:48,120 Speaker 1: but it doesn't it's not used to transport oxygen. It 290 00:14:48,120 --> 00:14:51,680 Speaker 1: transports things like hormones that trigger molting and things like that, 291 00:14:51,720 --> 00:14:54,520 Speaker 1: but the oxygen just diffuses throughout the body. 292 00:14:55,400 --> 00:14:57,840 Speaker 3: Yeah, you know, an inch worm, it is like a 293 00:14:57,840 --> 00:15:01,280 Speaker 3: little accordion, And if you could figure out how to 294 00:15:01,320 --> 00:15:07,000 Speaker 3: build and insert a tiny little like wooden reed in 295 00:15:07,040 --> 00:15:10,560 Speaker 3: each spiracle, that little thing might sound like an accordion 296 00:15:10,600 --> 00:15:11,040 Speaker 3: as it moved. 297 00:15:11,080 --> 00:15:13,920 Speaker 2: That'd be pretty neat, kind of cruel to I imagine. 298 00:15:14,160 --> 00:15:17,880 Speaker 1: Yeah, I mean probably if you're sticking wood in the 299 00:15:17,920 --> 00:15:21,200 Speaker 1: tiny breathing holes of a caterpillar. I don't think it would. 300 00:15:21,360 --> 00:15:21,840 Speaker 2: Don't try that. 301 00:15:22,680 --> 00:15:25,440 Speaker 1: By the way, Chuck, did I tell you that caterpillar 302 00:15:25,520 --> 00:15:29,960 Speaker 1: is from the old French chateapellos, which means shaggy cat. 303 00:15:30,480 --> 00:15:33,760 Speaker 3: Oh, like the actor Timothy Chatapellos? Is that you know 304 00:15:33,840 --> 00:15:35,080 Speaker 3: that's Timothy Shallomey? 305 00:15:35,120 --> 00:15:39,200 Speaker 1: Sorry, right, Yeah, Timothy. Shaggy cat would be that name. 306 00:15:39,280 --> 00:15:40,520 Speaker 2: Kind of looks like a shaggy cat. 307 00:15:40,560 --> 00:15:43,360 Speaker 1: But apparently they think it was the the is it 308 00:15:43,400 --> 00:15:48,760 Speaker 1: the wooly bully caterpillar that? Yeah, they think that that 309 00:15:48,880 --> 00:15:51,520 Speaker 1: was the original shaggy cat and it's just kind of 310 00:15:51,520 --> 00:15:54,000 Speaker 1: caught on from there, But that's where caterpillar comes from. 311 00:15:54,520 --> 00:15:57,840 Speaker 3: Yeah, And speaking of wily bully, you notice on caterpillars 312 00:15:57,880 --> 00:16:01,080 Speaker 3: a lot of times those little hairs or little quills 313 00:16:01,120 --> 00:16:04,800 Speaker 3: or spines those are called Oh man, we've even had 314 00:16:04,840 --> 00:16:06,680 Speaker 3: scientists tell us how to pronounce that ae. 315 00:16:07,640 --> 00:16:08,280 Speaker 2: Is it? Stay? 316 00:16:09,240 --> 00:16:10,160 Speaker 1: That's what I think it is. 317 00:16:10,240 --> 00:16:13,640 Speaker 3: Yeah, it's either that or we've been getting it wrong. 318 00:16:13,680 --> 00:16:14,320 Speaker 2: I can't remember. 319 00:16:14,400 --> 00:16:16,920 Speaker 3: But everyone is like in science guys, anytimes it's AE, 320 00:16:17,640 --> 00:16:21,160 Speaker 3: you pronounce the blank and I can't remember which one 321 00:16:21,200 --> 00:16:25,440 Speaker 3: it is. Oh, it's either set or SETAE. And now 322 00:16:25,600 --> 00:16:27,360 Speaker 3: we're gonna get more emails. And maybe I should just 323 00:16:27,400 --> 00:16:29,240 Speaker 3: put a sticky note on my laptop so i'll always 324 00:16:29,280 --> 00:16:32,160 Speaker 3: remember that. But that's what they're called, and they have 325 00:16:32,240 --> 00:16:35,960 Speaker 3: a lot of functions. They can deter things that want 326 00:16:36,000 --> 00:16:39,200 Speaker 3: to eat caterpillars because a lot of times these things 327 00:16:39,240 --> 00:16:42,480 Speaker 3: carry little irritants and toxins. And you just put a 328 00:16:42,520 --> 00:16:44,880 Speaker 3: pin in that for our very final segment at the end. 329 00:16:44,920 --> 00:16:52,000 Speaker 3: But like you said, yeah, but you can get, you know, 330 00:16:52,120 --> 00:16:55,000 Speaker 3: little little irritated bumps sometimes if you handle the wrong caterpillar. 331 00:16:55,040 --> 00:16:57,000 Speaker 1: Oh yeah, and you shouldn't handle a category get much 332 00:16:57,000 --> 00:17:00,000 Speaker 1: worse than that too. Yeah, if you've ever touched the caterpillar, 333 00:17:00,480 --> 00:17:02,560 Speaker 1: That's why I was referring too earlier, Like as a kid, 334 00:17:02,600 --> 00:17:05,400 Speaker 1: I remember touching one and just being like, oh my god, 335 00:17:05,440 --> 00:17:09,720 Speaker 1: what what just happened? And it hurt very badly, I 336 00:17:09,760 --> 00:17:13,000 Speaker 1: remember distinctly, but I still love caterpillars after that. 337 00:17:14,040 --> 00:17:17,879 Speaker 3: I remember there was one kind and someone will know 338 00:17:17,920 --> 00:17:20,200 Speaker 3: what kind ofness is, but I think it was sort 339 00:17:20,200 --> 00:17:24,920 Speaker 3: of yellow and black, and we would, you know, put 340 00:17:24,920 --> 00:17:27,959 Speaker 3: our finger on the ground and the caterpillar would crawl 341 00:17:28,119 --> 00:17:31,439 Speaker 3: up our hand and then we would like get a 342 00:17:31,520 --> 00:17:33,880 Speaker 3: leaf and have it crawl off. So I don't think 343 00:17:33,880 --> 00:17:35,719 Speaker 3: we harmed the caterpillar. We were just sitting it kind 344 00:17:35,720 --> 00:17:37,879 Speaker 3: of crawl on us for a minute. But and I 345 00:17:37,920 --> 00:17:40,160 Speaker 3: wasn't touching the spine, so I never got that irritation. 346 00:17:40,320 --> 00:17:43,239 Speaker 3: But I used to love doing that, and I just 347 00:17:43,280 --> 00:17:46,760 Speaker 3: thought that was so cool that they I guess now 348 00:17:46,880 --> 00:17:49,480 Speaker 3: knowing that they're blind, that there's like crawling on a stick, 349 00:17:49,680 --> 00:17:51,600 Speaker 3: and it's like, now I'm crawling on a finger. 350 00:17:51,640 --> 00:17:53,920 Speaker 1: Right, Yeah that's cute. 351 00:17:54,320 --> 00:17:56,000 Speaker 2: But yeah, you wouldn't stick like kid fingers. 352 00:17:56,000 --> 00:17:58,639 Speaker 1: You wouldn't have been touching the hair like structures, so 353 00:17:58,720 --> 00:18:00,320 Speaker 1: it wouldn't have stung you. It's not like I don't 354 00:18:00,320 --> 00:18:02,359 Speaker 1: think it's an active process. I think it's a passive 355 00:18:02,400 --> 00:18:04,639 Speaker 1: thing where you just touch it and they're not like 356 00:18:04,760 --> 00:18:07,399 Speaker 1: die die die. It's just like, right, you just touched 357 00:18:07,400 --> 00:18:10,240 Speaker 1: it and it did its Thingah. 358 00:18:10,760 --> 00:18:11,520 Speaker 2: Yeah, I get the feeling. 359 00:18:11,560 --> 00:18:14,480 Speaker 3: The caterpillars even like, sorry, man, and you know it 360 00:18:14,520 --> 00:18:16,280 Speaker 3: shouldn't touch me, but sorry. 361 00:18:16,480 --> 00:18:19,560 Speaker 1: Most caterpillars seem rather chill, but not all of them are. 362 00:18:20,040 --> 00:18:22,680 Speaker 1: I was not happy to find this out. I find 363 00:18:22,720 --> 00:18:27,800 Speaker 1: this rather unpleasant. But there's some species of caterpillars in 364 00:18:27,840 --> 00:18:32,119 Speaker 1: Hawaii that are actually carnivores. Far and away, most species 365 00:18:32,160 --> 00:18:38,280 Speaker 1: of caterpillars, and hence butterflies are are herbivores. They just 366 00:18:38,400 --> 00:18:41,800 Speaker 1: eat leaves, That's what they do. They eat leaves and shoots. Wait, 367 00:18:41,920 --> 00:18:47,719 Speaker 1: eat shoots and leaves. So there's the ones in Hawaii, though, 368 00:18:47,960 --> 00:18:51,640 Speaker 1: they'll eat snails. And not only do they eat snails, 369 00:18:51,720 --> 00:18:55,439 Speaker 1: it's really awful. They tie the snails to, say, like 370 00:18:55,480 --> 00:18:57,960 Speaker 1: a twig or a leaf or something, using spinnerets. They 371 00:18:58,040 --> 00:19:01,600 Speaker 1: have silk producing organs, and they'll tie the snail, the 372 00:19:01,600 --> 00:19:03,840 Speaker 1: whole shell and all to like a twig so the 373 00:19:03,880 --> 00:19:06,080 Speaker 1: snail can't get away, and then they climb into the 374 00:19:06,080 --> 00:19:08,080 Speaker 1: shell and eat the snail alive. 375 00:19:09,080 --> 00:19:10,360 Speaker 2: It is horrifying. 376 00:19:10,760 --> 00:19:13,199 Speaker 1: I don't like that particular kind of caterpillar, but I 377 00:19:13,280 --> 00:19:14,000 Speaker 1: like all the rest. 378 00:19:14,720 --> 00:19:17,240 Speaker 2: Yeah, they tie it down and eat it. 379 00:19:17,440 --> 00:19:20,320 Speaker 1: So awful. Imagine it just coming into your house too, 380 00:19:20,359 --> 00:19:22,560 Speaker 1: and you're like, please know, and you have no escape. 381 00:19:22,560 --> 00:19:23,960 Speaker 1: And that's that. 382 00:19:24,840 --> 00:19:28,000 Speaker 3: Yeah, it was pretty horrifying to read that and frankly disappointing. 383 00:19:28,080 --> 00:19:35,880 Speaker 3: But there's also a brand, a brand in Australia brand Hey. 384 00:19:36,440 --> 00:19:38,240 Speaker 3: They lay their eggs and ant hills and when they 385 00:19:38,240 --> 00:19:40,959 Speaker 3: come out, they will eat those ants. But aside from that, 386 00:19:41,000 --> 00:19:45,600 Speaker 3: in the Hawaiian they, like you said, are strictly herbivores 387 00:19:46,840 --> 00:19:50,360 Speaker 3: and they are using those leaves also to camouflage themselves. 388 00:19:51,600 --> 00:19:54,480 Speaker 3: They have a lot of great mechanisms to keep this 389 00:19:54,640 --> 00:19:58,040 Speaker 3: not quite octopus level, but they seem like they're you know, 390 00:19:58,480 --> 00:20:00,160 Speaker 3: I don't know if it's wrong to use words smart, 391 00:20:00,240 --> 00:20:04,160 Speaker 3: but they know to feed under leaves so birds can't 392 00:20:04,160 --> 00:20:09,240 Speaker 3: see them. They also have some natural camouflage, like sometimes 393 00:20:09,280 --> 00:20:13,000 Speaker 3: those eyes can look like the fake eyes can look 394 00:20:13,040 --> 00:20:13,560 Speaker 3: like snakes. 395 00:20:13,560 --> 00:20:14,480 Speaker 1: Did you see that one? 396 00:20:15,160 --> 00:20:16,359 Speaker 2: Yeah, it looks like a snake. 397 00:20:16,440 --> 00:20:19,280 Speaker 1: Yeah, it looks like a bright green snake. And apparently 398 00:20:19,320 --> 00:20:22,240 Speaker 1: they'll arrange themselves sometimes to make it look like a 399 00:20:22,359 --> 00:20:26,119 Speaker 1: long snake, Like three hundred caterpillars will get together and 400 00:20:26,200 --> 00:20:28,399 Speaker 1: line up and it's like Wow, there's a snake. No, 401 00:20:28,560 --> 00:20:30,200 Speaker 1: it's a line of caterpillars. 402 00:20:30,600 --> 00:20:33,560 Speaker 3: Yeah, like a lot of them are solitary caterpillars, but 403 00:20:33,600 --> 00:20:38,119 Speaker 3: there is what was the one in particular that traveling. 404 00:20:37,720 --> 00:20:40,880 Speaker 1: Groups gregarious caterpillars. 405 00:20:41,119 --> 00:20:42,639 Speaker 3: Yeah, I get the feeling. Those are the ones that 406 00:20:42,720 --> 00:20:45,120 Speaker 3: might do the old snake one too. 407 00:20:45,359 --> 00:20:48,040 Speaker 1: Yes, I think those are swallow tails and they might 408 00:20:48,040 --> 00:20:50,880 Speaker 1: be gregarious. Yeah. So I say we take a break, Chuck, 409 00:20:51,240 --> 00:20:53,359 Speaker 1: and then we'll come back, and I propose that we 410 00:20:53,440 --> 00:20:55,600 Speaker 1: talked more about caterpillars. 411 00:20:56,280 --> 00:20:56,920 Speaker 2: Let's do it. 412 00:21:07,320 --> 00:21:20,000 Speaker 1: Softly jaw. Okay, So you mentioned a couple of things 413 00:21:20,000 --> 00:21:22,800 Speaker 1: that they do to protect themselves, camouflage, just eating a 414 00:21:22,800 --> 00:21:25,760 Speaker 1: little bit on the underside of a leaf. There's a 415 00:21:25,760 --> 00:21:28,000 Speaker 1: lot of other things that they can do too. There's 416 00:21:28,240 --> 00:21:32,280 Speaker 1: there's so many different species of caterpillar because again we're 417 00:21:32,320 --> 00:21:34,760 Speaker 1: talking about moths and butterflies, they're not just all the 418 00:21:34,800 --> 00:21:38,120 Speaker 1: same thing. That they've developed all sorts of really interesting 419 00:21:38,640 --> 00:21:42,840 Speaker 1: means of defense. One of the ways they say the 420 00:21:42,840 --> 00:21:47,520 Speaker 1: best defense is shooting your poop out, and there's a 421 00:21:47,600 --> 00:21:50,480 Speaker 1: type of caterpillar that does that. I think it's the 422 00:21:50,760 --> 00:21:54,840 Speaker 1: it's the silver spotted skipper and skipper is basically a 423 00:21:54,880 --> 00:21:58,919 Speaker 1: type of butterfly, and it shoots its waist called frast 424 00:21:59,000 --> 00:22:03,240 Speaker 1: it's poop as far as five feet from itself in 425 00:22:03,359 --> 00:22:06,119 Speaker 1: order to keep predators from being able to track it 426 00:22:06,359 --> 00:22:07,439 Speaker 1: back to its source. 427 00:22:08,400 --> 00:22:14,040 Speaker 3: That explains that old saying, you ain't nothing but caterpillar frass. 428 00:22:14,520 --> 00:22:16,239 Speaker 2: M I never knew what they mean. 429 00:22:16,320 --> 00:22:18,480 Speaker 1: You're really good at jumping, that's what they say to you. 430 00:22:20,000 --> 00:22:21,800 Speaker 3: Yeah, and that's one of the things they do, like 431 00:22:21,920 --> 00:22:24,200 Speaker 3: several other things, which is it all sort of falls 432 00:22:24,240 --> 00:22:28,080 Speaker 3: to the umbrella of I don't want anyone to know 433 00:22:28,160 --> 00:22:31,680 Speaker 3: I'm like even here, So a poop will be a 434 00:22:31,680 --> 00:22:32,639 Speaker 3: big giveaway obviously. 435 00:22:32,760 --> 00:22:35,120 Speaker 2: Another as if, like they love to eat. 436 00:22:35,200 --> 00:22:38,720 Speaker 3: If if a predator sees a ton of chewed up 437 00:22:38,800 --> 00:22:41,800 Speaker 3: leaves everywhere, they're gonna be like, ooh, the caterpillars nearby. 438 00:22:41,840 --> 00:22:44,240 Speaker 3: I love to eat those things. So as much as 439 00:22:44,280 --> 00:22:47,640 Speaker 3: those caterpillars love to eat, it is their singular purpose 440 00:22:47,640 --> 00:22:51,679 Speaker 3: in life. They will many times just eat little bits 441 00:22:52,160 --> 00:22:55,679 Speaker 3: off of many, many leaves to kind of disguise the fact, like, 442 00:22:55,680 --> 00:22:58,400 Speaker 3: no caterpillar here. There's just a few nibbles here and there, 443 00:22:58,520 --> 00:23:01,359 Speaker 3: yeah leaf rather than just yeah, rather than just like 444 00:23:01,400 --> 00:23:04,280 Speaker 3: taking a leaf down to its spine. 445 00:23:04,400 --> 00:23:07,159 Speaker 1: Yeah, which any even the dumbest of birds can be Like, 446 00:23:07,200 --> 00:23:08,920 Speaker 1: there's a caterpillar around here. 447 00:23:09,080 --> 00:23:10,719 Speaker 2: And you know they want to do that, but they 448 00:23:10,840 --> 00:23:11,560 Speaker 2: still don't do it. 449 00:23:11,640 --> 00:23:16,720 Speaker 1: I know. Caterpillars have tremendous self control, you doo. We 450 00:23:16,840 --> 00:23:19,439 Speaker 1: mentioned that they have spinnerets so that they can spin silk, 451 00:23:19,480 --> 00:23:21,560 Speaker 1: and they use it to great effect in all sorts 452 00:23:21,600 --> 00:23:28,000 Speaker 1: of different ways, including defense. Apparently some kinds of caterpillars 453 00:23:28,040 --> 00:23:31,040 Speaker 1: will like spin a little thing of silk that they'll 454 00:23:31,040 --> 00:23:33,640 Speaker 1: attach to the leaf they're on, and when a predator comes, 455 00:23:33,680 --> 00:23:37,040 Speaker 1: they just jump off, basically like John McClean and die Hard, 456 00:23:37,560 --> 00:23:40,240 Speaker 1: and they're attached to the silk, so they swing into 457 00:23:40,800 --> 00:23:43,640 Speaker 1: you know, a window in the Knokotomi building and then 458 00:23:43,640 --> 00:23:45,760 Speaker 1: climb back up when the bird goes away. But they 459 00:23:45,840 --> 00:23:49,040 Speaker 1: just jump off the leaf to get away. I'll bet 460 00:23:49,040 --> 00:23:50,560 Speaker 1: that's pretty neat to see. 461 00:23:50,440 --> 00:23:53,880 Speaker 2: That's right. And to combat jet lag, they make fists 462 00:23:53,920 --> 00:23:54,440 Speaker 2: with their toes. 463 00:23:54,640 --> 00:23:56,040 Speaker 1: Yeah, what do you know. 464 00:23:56,359 --> 00:23:58,520 Speaker 3: I wonder if they leap. I'd like to see that 465 00:23:58,640 --> 00:24:00,760 Speaker 3: in slow motion. I wonder if all of those legs 466 00:24:00,760 --> 00:24:04,280 Speaker 3: and pro legs at once do that in concert that 467 00:24:04,280 --> 00:24:05,040 Speaker 3: would be pretty cool. 468 00:24:05,119 --> 00:24:07,320 Speaker 1: Or if they inch, they just shoot themselves up. They 469 00:24:07,320 --> 00:24:10,120 Speaker 1: inch so quickly that shoots them right off of the leaf. 470 00:24:10,840 --> 00:24:12,240 Speaker 2: Yeah. 471 00:24:12,280 --> 00:24:14,840 Speaker 3: So yeah, that's one use of the silk is like 472 00:24:14,960 --> 00:24:20,159 Speaker 3: literal climbing rope. And like we said, like the solo caterpillar, 473 00:24:20,440 --> 00:24:23,080 Speaker 3: which is many of the I want to say, brands, 474 00:24:23,240 --> 00:24:26,520 Speaker 3: what a dummy varieties species. 475 00:24:26,560 --> 00:24:26,959 Speaker 2: Here you go. 476 00:24:28,440 --> 00:24:31,119 Speaker 3: You know, there's going around, they're eating, they're they're laying 477 00:24:31,119 --> 00:24:35,280 Speaker 3: an egg. They're using the silk as as like a lasso. 478 00:24:35,400 --> 00:24:38,320 Speaker 3: Or maybe they might make a little nest. Like we 479 00:24:38,359 --> 00:24:41,959 Speaker 3: said earlier, maybe they might restrain that that snail. But 480 00:24:42,000 --> 00:24:45,200 Speaker 3: those gregarious kinds that live in big groups, they really 481 00:24:45,280 --> 00:24:49,120 Speaker 3: get going with the silk production. They make big nests 482 00:24:49,880 --> 00:24:51,520 Speaker 3: in trees and around tree trunks. 483 00:24:51,760 --> 00:24:53,119 Speaker 1: You've probably seen them before. 484 00:24:53,400 --> 00:24:54,800 Speaker 2: Oh yeah, they're like big tents. 485 00:24:54,840 --> 00:24:58,080 Speaker 3: Basically, if you've seen big you know, it looks like 486 00:24:59,440 --> 00:25:02,040 Speaker 3: sort of a real dense spider web. I guess sometimes 487 00:25:02,040 --> 00:25:03,159 Speaker 3: those are spiders, right. 488 00:25:03,440 --> 00:25:05,600 Speaker 1: Yeah, there's some kinds of spiders that do that, but 489 00:25:05,640 --> 00:25:07,879 Speaker 1: I think probably more often than not what you're seeing 490 00:25:07,960 --> 00:25:10,160 Speaker 1: or gregarious caterpillars getting together. 491 00:25:10,760 --> 00:25:15,879 Speaker 3: Yeah, but they also use their little spinnerets as like 492 00:25:15,920 --> 00:25:18,440 Speaker 3: a trail, like, hey, we're all going this way and 493 00:25:18,480 --> 00:25:21,000 Speaker 3: we're gonna lay this little trail and we know that. 494 00:25:21,080 --> 00:25:22,280 Speaker 3: You know, if you want to get home, this is 495 00:25:22,320 --> 00:25:22,920 Speaker 3: how you get home. 496 00:25:23,080 --> 00:25:26,520 Speaker 1: What's neat is those trails are often intergenerational and so 497 00:25:26,880 --> 00:25:31,520 Speaker 1: like an older generation will leave there that that silk 498 00:25:31,600 --> 00:25:34,240 Speaker 1: for the next generation to use, and that next generation 499 00:25:34,359 --> 00:25:36,919 Speaker 1: then can grow bigger and stronger because they didn't have 500 00:25:36,960 --> 00:25:40,119 Speaker 1: to use that energy to create the silk for that 501 00:25:40,119 --> 00:25:42,920 Speaker 1: that leads to the to the food source. I thought 502 00:25:42,960 --> 00:25:43,840 Speaker 1: that was pretty nice. 503 00:25:44,320 --> 00:25:48,919 Speaker 2: Yeah, like handy down silk, Yeah exactly, or like you 504 00:25:48,960 --> 00:25:50,800 Speaker 2: know link of rope that grandpa gave. 505 00:25:50,680 --> 00:25:54,359 Speaker 1: You, Yeah, same thing, hand me down silk, length of 506 00:25:54,480 --> 00:25:55,280 Speaker 1: rope from grandpa. 507 00:25:56,040 --> 00:25:56,520 Speaker 4: What else? 508 00:25:57,520 --> 00:26:00,360 Speaker 1: There's another thing too that we haven't quite figured it out, 509 00:26:00,359 --> 00:26:03,000 Speaker 1: and we I mean the entomology world, and by we 510 00:26:03,240 --> 00:26:08,399 Speaker 1: also mean them that it may or may not be 511 00:26:08,560 --> 00:26:12,040 Speaker 1: advantageous to live in a gregarious community as opposed to 512 00:26:12,119 --> 00:26:16,680 Speaker 1: being solitary. Because yes, it's easier to build a big 513 00:26:16,720 --> 00:26:18,800 Speaker 1: shelter for yourself if you have a bunch of other 514 00:26:18,840 --> 00:26:22,359 Speaker 1: friends helping you. It's easier to find food if you 515 00:26:22,400 --> 00:26:24,480 Speaker 1: have other people looking at the same time you are 516 00:26:24,520 --> 00:26:27,280 Speaker 1: and then telling you what they found. But at the 517 00:26:27,280 --> 00:26:30,760 Speaker 1: same time you're also competing with those same people or 518 00:26:30,760 --> 00:26:33,000 Speaker 1: those same caterpillars. I should say, yeah, and that's a 519 00:26:33,000 --> 00:26:35,359 Speaker 1: big that can be a big problem too. I like it. 520 00:26:35,400 --> 00:26:39,359 Speaker 3: Caterpillars are people too, exactly, and if there's a disease, 521 00:26:39,400 --> 00:26:42,720 Speaker 3: you know it's gonna spread pretty readily within that population 522 00:26:43,520 --> 00:26:46,439 Speaker 3: if they're all living together. But I think you know, 523 00:26:46,480 --> 00:26:48,400 Speaker 3: we've held off long enough. We should we should talk 524 00:26:48,400 --> 00:26:53,000 Speaker 3: about that metamorphosis, which is what everyone wants to know about, 525 00:26:53,480 --> 00:26:56,280 Speaker 3: and that is basically a caterpillar is doing its thing. 526 00:26:56,640 --> 00:26:59,760 Speaker 3: It's going through those molts. It's that fifth molt, and 527 00:26:59,800 --> 00:27:03,159 Speaker 3: they say, you know what, it's been great, But I 528 00:27:03,160 --> 00:27:05,720 Speaker 3: think I'm tired of eating. Finally, m I'm gonna go 529 00:27:05,800 --> 00:27:08,560 Speaker 3: off and wander off into the woods and find a 530 00:27:08,600 --> 00:27:12,640 Speaker 3: safe spot and I'm going to pupeate everybody, and when 531 00:27:12,680 --> 00:27:16,160 Speaker 3: you see me again, I will be the most beautiful 532 00:27:16,200 --> 00:27:16,920 Speaker 3: thing you've ever seen. 533 00:27:17,040 --> 00:27:21,440 Speaker 1: Yeah, pretty neat. And this is where the terminology gets 534 00:27:21,480 --> 00:27:25,200 Speaker 1: really confusing. If you do any research on. 535 00:27:25,160 --> 00:27:27,120 Speaker 2: This, yeah, I can for sure. 536 00:27:27,240 --> 00:27:31,479 Speaker 1: So the pupa is often referred to as the form 537 00:27:31,560 --> 00:27:38,560 Speaker 1: the body form that the centipede that the caterpillar is 538 00:27:38,640 --> 00:27:44,080 Speaker 1: in as it enters the transformation. Right, Yes, it's actually 539 00:27:44,119 --> 00:27:47,480 Speaker 1: the life stage, like the caterpillar is the larval life stage, 540 00:27:47,720 --> 00:27:50,360 Speaker 1: the butterfly or the moth is the adult. The pupa 541 00:27:50,480 --> 00:27:53,280 Speaker 1: is the life stage in between. But for all intents 542 00:27:53,320 --> 00:27:56,480 Speaker 1: and purposes, you can also say that's a butterfly pupa, 543 00:27:56,520 --> 00:28:01,960 Speaker 1: although or that's a moth pupa. Right, that's the easiest, 544 00:28:01,960 --> 00:28:04,440 Speaker 1: most understandable part of it. It starts to get really 545 00:28:04,440 --> 00:28:09,280 Speaker 1: strange from there because the butterfly caterpillar when it emerges 546 00:28:09,320 --> 00:28:12,080 Speaker 1: from that fifth mold, it has a special kind of 547 00:28:12,520 --> 00:28:16,879 Speaker 1: skin on it, and over time, when it turns upside 548 00:28:16,920 --> 00:28:19,960 Speaker 1: down and hangs from a leaf and begins its transformation, 549 00:28:20,280 --> 00:28:23,639 Speaker 1: that skin hardens and it forms basically the protective layer 550 00:28:23,880 --> 00:28:27,840 Speaker 1: that's going to protect that caterpillar turned butterfly as it 551 00:28:27,960 --> 00:28:32,240 Speaker 1: undergoes its transformation, and that's called the crystalis But just 552 00:28:32,400 --> 00:28:35,360 Speaker 1: butterfly caterpillars do that, right, not moths. 553 00:28:36,640 --> 00:28:38,600 Speaker 2: I think that's right. 554 00:28:38,720 --> 00:28:41,800 Speaker 1: And then I think it's just moths because they don't 555 00:28:41,800 --> 00:28:46,080 Speaker 1: form chrysalis or crysalie. They are the only ones to 556 00:28:46,120 --> 00:28:48,120 Speaker 1: spin a cocoon to protect themselves. 557 00:28:48,200 --> 00:28:51,400 Speaker 3: Correct, right, and that cocoon starts talk kind of soft, 558 00:28:51,400 --> 00:28:54,880 Speaker 3: but that eventually hardens as well. But I think that's right. 559 00:28:56,280 --> 00:29:00,760 Speaker 3: But the chrysalis itself is not some like shell they 560 00:29:00,760 --> 00:29:01,400 Speaker 3: build like it. 561 00:29:01,640 --> 00:29:03,080 Speaker 2: It is. It is the thing. 562 00:29:03,240 --> 00:29:04,920 Speaker 1: Yeah, it's the outer layer of skin. 563 00:29:05,640 --> 00:29:08,880 Speaker 3: Okay, yeah, because it can actually twitch and move as 564 00:29:08,920 --> 00:29:12,960 Speaker 3: a defense. Yeah, like it's it's a thinking sentient, well 565 00:29:13,000 --> 00:29:16,080 Speaker 3: not thinking necessarily, but it is a shell that is 566 00:29:16,400 --> 00:29:18,640 Speaker 3: a living thing. It's not like let me build this, 567 00:29:19,240 --> 00:29:22,320 Speaker 3: you know, this thing to get into. It is the 568 00:29:22,320 --> 00:29:23,200 Speaker 3: thing that it is in. 569 00:29:23,320 --> 00:29:26,880 Speaker 1: Right, So imagine if you underwent this transformation, you probably 570 00:29:26,920 --> 00:29:29,720 Speaker 1: go off into a corner and kind of ball up, 571 00:29:29,880 --> 00:29:32,080 Speaker 1: maybe in a bit of a fetal position. But then 572 00:29:32,160 --> 00:29:35,240 Speaker 1: imagine as part of this process, all of your skin 573 00:29:35,360 --> 00:29:39,720 Speaker 1: fused together and turned into like an outer shell rather 574 00:29:39,840 --> 00:29:43,280 Speaker 1: than you know this this you know, this thing covering you. 575 00:29:43,360 --> 00:29:46,160 Speaker 1: It's it's like this now this big ball that you're 576 00:29:46,240 --> 00:29:49,600 Speaker 1: now kind of separated from inside and you're doing your 577 00:29:49,600 --> 00:29:52,680 Speaker 1: thing inside. That's kind of like what the chrysalis is like. 578 00:29:53,520 --> 00:29:56,800 Speaker 3: Yeah, And so we mentioned the silk, like the uses 579 00:29:56,840 --> 00:29:57,720 Speaker 3: as like a climbing rope. 580 00:29:57,760 --> 00:29:59,240 Speaker 2: And stuff like that, and to build little nests. 581 00:30:00,000 --> 00:30:03,400 Speaker 3: It really comes in handy when it's time to pupate 582 00:30:04,120 --> 00:30:06,720 Speaker 3: because they use this silk in a variety of ways. 583 00:30:06,520 --> 00:30:08,520 Speaker 3: There's more than one way to skin a cat, and 584 00:30:08,560 --> 00:30:12,720 Speaker 3: there's more than one way for a caterpillar to metamorphosize. Sometimes, 585 00:30:12,720 --> 00:30:14,560 Speaker 3: like you said, they hang upside down from that leaf, 586 00:30:14,960 --> 00:30:18,400 Speaker 3: so they've spun like a little silk pad that attaches 587 00:30:18,480 --> 00:30:22,440 Speaker 3: to something. Sometimes they create like a little hammock. Sometimes 588 00:30:22,480 --> 00:30:25,800 Speaker 3: they make like a little sling in concert with a stick. 589 00:30:26,520 --> 00:30:28,320 Speaker 3: There are different ways that they can do this, but 590 00:30:28,480 --> 00:30:31,959 Speaker 3: it always involves using silk to sort of stabilize itself, 591 00:30:32,000 --> 00:30:34,760 Speaker 3: either upside down or right side up or sideways or whatever. Right, 592 00:30:35,360 --> 00:30:38,480 Speaker 3: and then they start to do that thing, whether it's 593 00:30:38,480 --> 00:30:42,600 Speaker 3: a moth spinning that cocoon or just the gradual transformation 594 00:30:42,960 --> 00:30:45,240 Speaker 3: of caterpillar into chrysalis. 595 00:30:45,720 --> 00:30:48,600 Speaker 1: Right. And then so once that happens, once the cocoon 596 00:30:48,760 --> 00:30:54,440 Speaker 1: is full or the crysalis is hardened, this and one 597 00:30:54,480 --> 00:30:57,720 Speaker 1: of the most amazing things that on Earth happens in there. 598 00:30:58,000 --> 00:31:00,600 Speaker 1: And it's neat because we've gotten to the point where 599 00:31:00,600 --> 00:31:05,200 Speaker 1: we have photography that can peer inside of this without 600 00:31:05,200 --> 00:31:09,840 Speaker 1: harming the caterpillar, and they have like time lapse videos 601 00:31:09,880 --> 00:31:12,960 Speaker 1: of this transformation. And as the thing turns more and 602 00:31:13,040 --> 00:31:16,760 Speaker 1: more into what's obviously like a butterfly or moth, and 603 00:31:16,800 --> 00:31:21,479 Speaker 1: you see it hanging upside down just forming it. It 604 00:31:21,520 --> 00:31:27,040 Speaker 1: looks like a cross between an hr Geiger painting and 605 00:31:27,720 --> 00:31:32,840 Speaker 1: Michael Crichton's Coma, the movie version. It's really neat, but 606 00:31:32,880 --> 00:31:35,400 Speaker 1: it also gives you this. It has this kind of 607 00:31:35,440 --> 00:31:39,600 Speaker 1: regal and majestic feel to it as well. I produced 608 00:31:39,600 --> 00:31:41,240 Speaker 1: a lot of emotions in me apparently. 609 00:31:42,040 --> 00:31:43,160 Speaker 2: Yeah, I mean it's. 610 00:31:45,360 --> 00:31:48,440 Speaker 3: This isn't the science y explanation, but it's almost as 611 00:31:48,520 --> 00:31:53,320 Speaker 3: if you can take a tray of put a bunch 612 00:31:53,360 --> 00:31:57,000 Speaker 3: of spaghetti and meatballs in a dish and cover it 613 00:31:57,080 --> 00:32:01,360 Speaker 3: up and then when you open it up it's a lasagna. Yeah, 614 00:32:01,400 --> 00:32:03,000 Speaker 3: and you're like, how did that happen? 615 00:32:03,160 --> 00:32:05,520 Speaker 2: Like how did that even happen? 616 00:32:05,760 --> 00:32:10,040 Speaker 1: So this is how it happens. The caterpillar breaks itself 617 00:32:10,080 --> 00:32:15,120 Speaker 1: down into a soup of cells, like it's basically like 618 00:32:15,160 --> 00:32:17,920 Speaker 1: a caterpillar soup for a while, and some of the 619 00:32:18,040 --> 00:32:22,640 Speaker 1: cells keep their form generally, or at least stay attached 620 00:32:22,680 --> 00:32:26,440 Speaker 1: to one another. So those leg cells, yeah, they change. 621 00:32:26,560 --> 00:32:29,800 Speaker 1: They look different, like a caterpillar's actual true legs look 622 00:32:29,840 --> 00:32:32,040 Speaker 1: different from the butterfly's true legs, but they're still the 623 00:32:32,040 --> 00:32:35,280 Speaker 1: same cells. They're just they rearrange themselves a little bit. 624 00:32:36,040 --> 00:32:40,000 Speaker 1: Most of the other cells just completely come apart, turn 625 00:32:40,080 --> 00:32:43,880 Speaker 1: into imaginal cells, which are analogous to our stem cells, 626 00:32:44,360 --> 00:32:46,360 Speaker 1: and that they can turn into any kind of cell. 627 00:32:46,760 --> 00:32:51,360 Speaker 1: And then it reconfigures itself using the same cells, same amount, 628 00:32:51,480 --> 00:32:57,240 Speaker 1: same everything into a butterfly. It reconfigures itself over the 629 00:32:57,280 --> 00:32:58,560 Speaker 1: course of about two weeks. 630 00:32:59,480 --> 00:33:03,400 Speaker 3: It's un Yeah, it really is, Like my brain breaks 631 00:33:03,880 --> 00:33:05,760 Speaker 3: every time I try to make sense, especially when you 632 00:33:05,760 --> 00:33:08,200 Speaker 3: see what comes out, you know, And I mean if 633 00:33:08,240 --> 00:33:11,840 Speaker 3: it came out looking like a dung beetle like that 634 00:33:11,880 --> 00:33:14,640 Speaker 3: would still be awesome. But to come out looking like 635 00:33:14,640 --> 00:33:17,760 Speaker 3: a butterfly with those iridescent wings, yeah, and the little 636 00:33:17,760 --> 00:33:20,440 Speaker 3: faces on those wings, it's just unbelievable. And I guess 637 00:33:21,120 --> 00:33:24,520 Speaker 3: I mean, evolutionarily speaking, this is all to eventually get 638 00:33:24,560 --> 00:33:25,680 Speaker 3: to like a pollinator. 639 00:33:26,720 --> 00:33:29,360 Speaker 1: I don't understand it. This is where I think they 640 00:33:29,480 --> 00:33:32,440 Speaker 1: that science has kind of thrown off. They're like, the 641 00:33:32,440 --> 00:33:35,479 Speaker 1: best explanation I saw is that it's better than having 642 00:33:36,840 --> 00:33:40,160 Speaker 1: two things compete for the same food source, but that 643 00:33:40,160 --> 00:33:43,959 Speaker 1: that doesn't really make any sense, you know, because that 644 00:33:44,000 --> 00:33:46,080 Speaker 1: doesn't make any sense to me at all. I don't 645 00:33:46,160 --> 00:33:48,560 Speaker 1: understand that. But that was the best explanation I saw, 646 00:33:48,600 --> 00:33:49,920 Speaker 1: and I didn't even understand it. 647 00:33:50,000 --> 00:33:53,680 Speaker 2: So as to the why, yeah, yeah, Like. 648 00:33:53,800 --> 00:33:58,640 Speaker 1: It's just so strange. It's I just don't understand it. 649 00:33:58,800 --> 00:34:02,200 Speaker 1: And everything goes through life like stages. We go through puberty, 650 00:34:02,520 --> 00:34:07,200 Speaker 1: we become adults, we go from infant babies to grown adults. 651 00:34:07,520 --> 00:34:10,680 Speaker 1: But there's not a period where we stop and over 652 00:34:10,719 --> 00:34:13,960 Speaker 1: the course of two weeks to completely reconfigure ourselves into 653 00:34:14,000 --> 00:34:16,520 Speaker 1: a new form. There's not that many things out there 654 00:34:16,520 --> 00:34:19,640 Speaker 1: that do do that, and we just don't fully understand 655 00:34:19,680 --> 00:34:22,239 Speaker 1: why it happens, and maybe we never will, and I 656 00:34:22,280 --> 00:34:23,800 Speaker 1: think that'd be just fine. 657 00:34:24,160 --> 00:34:26,640 Speaker 3: Although I would argue that the Josh Clark I knew 658 00:34:27,040 --> 00:34:30,359 Speaker 3: fifteen years ago his caterpillar like has now emerged as 659 00:34:30,400 --> 00:34:31,680 Speaker 3: a beautiful butterfly. 660 00:34:31,440 --> 00:34:36,879 Speaker 1: Thank you. I remember reading when Christopher Hitchins became a conservative, 661 00:34:37,520 --> 00:34:40,920 Speaker 1: one of the Liberal members of parliament said that this 662 00:34:41,000 --> 00:34:43,320 Speaker 1: is one of the rare instances where the butterfly turns 663 00:34:43,320 --> 00:34:46,480 Speaker 1: back on lug Oh no, yeah. 664 00:34:46,520 --> 00:34:48,080 Speaker 2: Wow, I'd like to hear what that exit. 665 00:34:48,400 --> 00:34:50,040 Speaker 1: I think I read that in two thousand and seven 666 00:34:50,080 --> 00:34:51,279 Speaker 1: and it still stuck with me. 667 00:34:51,719 --> 00:34:54,359 Speaker 2: Yeah, that's a good one. We didn't take our second break, 668 00:34:54,360 --> 00:34:54,640 Speaker 2: did we. 669 00:34:54,840 --> 00:34:55,520 Speaker 1: Nope, it's time. 670 00:34:55,640 --> 00:34:57,360 Speaker 2: All right, Well let's take our second break. 671 00:34:57,600 --> 00:35:00,480 Speaker 3: We'll probably still be talking about this metamorphosis, you know, 672 00:35:00,560 --> 00:35:01,839 Speaker 3: when we come back, So just be. 673 00:35:01,840 --> 00:35:14,880 Speaker 4: Prepared softly, jaws. 674 00:35:18,640 --> 00:35:24,200 Speaker 2: Soft all right. 675 00:35:24,960 --> 00:35:28,480 Speaker 3: I mean, I guess we're done talking about metamorphosis. It's 676 00:35:28,520 --> 00:35:33,680 Speaker 3: called holo metabolism. Yeah, that full transformation. And I don't 677 00:35:33,760 --> 00:35:36,120 Speaker 3: think he said it takes a couple of weeks generally. 678 00:35:36,239 --> 00:35:39,520 Speaker 1: Yeah, I saw about two weeks something like that on average. 679 00:35:39,640 --> 00:35:41,479 Speaker 1: It can be more or less depending on the weather 680 00:35:41,560 --> 00:35:41,960 Speaker 1: and stuff. 681 00:35:42,200 --> 00:35:44,600 Speaker 3: Yeah, and I took it as depending on the weather. 682 00:35:44,760 --> 00:35:46,840 Speaker 3: Meaning is that they don't want to do this in 683 00:35:46,920 --> 00:35:50,080 Speaker 3: the middle of winter. So if they get started and 684 00:35:50,239 --> 00:35:53,200 Speaker 3: like winter comes early, maybe it'll they'll just stay in 685 00:35:53,280 --> 00:35:53,960 Speaker 3: there for a few months. 686 00:35:54,000 --> 00:35:56,359 Speaker 1: Is that right? There are some species that over winter 687 00:35:56,719 --> 00:36:00,200 Speaker 1: in their cocoon or in their chrysalis, and that's part 688 00:36:00,239 --> 00:36:02,239 Speaker 1: of their thing. But I saw that there's that the 689 00:36:02,400 --> 00:36:04,800 Speaker 1: ideal there's an ideal temperature. That's what I took it 690 00:36:04,880 --> 00:36:07,200 Speaker 1: to mean, oh, okay, and that the ideal temperature is 691 00:36:07,239 --> 00:36:10,240 Speaker 1: twenty one degrees celsius. And get this, buddy, I converted 692 00:36:10,280 --> 00:36:13,040 Speaker 1: to farent height. You s we talked about the other day. 693 00:36:13,120 --> 00:36:13,920 Speaker 2: So you did it yourself. 694 00:36:14,480 --> 00:36:17,480 Speaker 1: Yeah, it's like, uh, I love it down. I could 695 00:36:17,520 --> 00:36:19,239 Speaker 1: do it again if I wanted to. But I'm just 696 00:36:19,320 --> 00:36:20,960 Speaker 1: gonna find what I wrote down. I think it's like 697 00:36:21,040 --> 00:36:22,879 Speaker 1: eighty eight eighty nine degrees. 698 00:36:22,880 --> 00:36:27,040 Speaker 3: Fahrenheits all right, I love it when after all these 699 00:36:27,120 --> 00:36:29,759 Speaker 3: eighty one it's eighty one, you're still brave enough to 700 00:36:29,760 --> 00:36:31,040 Speaker 3: put yourself out there with math. 701 00:36:31,400 --> 00:36:33,919 Speaker 1: Here, I'll just do this, okay. So here we find 702 00:36:34,000 --> 00:36:37,000 Speaker 1: fahrenheit from twenty one degree celsius. So it's twenty one 703 00:36:37,400 --> 00:36:40,919 Speaker 1: plus thirty two. Okay, we're getting everything back equal again. 704 00:36:41,200 --> 00:36:45,040 Speaker 1: So what is that fifty six times one point eight 705 00:36:45,239 --> 00:36:46,960 Speaker 1: I believe comes to eighty one. 706 00:36:48,160 --> 00:36:52,560 Speaker 3: When was the last time you did sort of written 707 00:36:52,640 --> 00:36:54,719 Speaker 3: down long division or something like that. 708 00:36:55,800 --> 00:36:57,359 Speaker 1: Oh it's been a long time. By the way, it's 709 00:36:57,400 --> 00:36:58,200 Speaker 1: eighty four point. 710 00:36:58,040 --> 00:37:00,600 Speaker 2: Six eighty four point six. Can you still do that stuff? 711 00:37:02,160 --> 00:37:05,160 Speaker 1: I don't know. Probably if I gave enough time to it. Sure, 712 00:37:05,480 --> 00:37:07,840 Speaker 1: I just did just it's not a part of my life. 713 00:37:08,320 --> 00:37:09,120 Speaker 1: Yeah anymore. 714 00:37:09,440 --> 00:37:11,800 Speaker 3: I actually don't know if I remember how to do 715 00:37:11,920 --> 00:37:16,640 Speaker 3: long division. I recently because Ruby is starting, you know, 716 00:37:16,840 --> 00:37:20,680 Speaker 3: like this past year started like multiplication and stuff and 717 00:37:21,360 --> 00:37:23,719 Speaker 3: came at me with like three digit times of two 718 00:37:23,800 --> 00:37:26,440 Speaker 3: digit and I was like, oh, you know what it was. 719 00:37:26,440 --> 00:37:27,360 Speaker 2: Like, I got it. I got it. 720 00:37:27,480 --> 00:37:29,520 Speaker 3: I remember, and I remember how to do that and 721 00:37:29,560 --> 00:37:34,000 Speaker 3: to carry the stuff. But I definitely don't think I 722 00:37:34,000 --> 00:37:35,240 Speaker 3: could do long division anymore. 723 00:37:35,239 --> 00:37:35,480 Speaker 2: I don't. 724 00:37:35,760 --> 00:37:37,680 Speaker 3: I sort of remember, but I don't think I would 725 00:37:38,200 --> 00:37:40,120 Speaker 3: fully be able to complete a problem. 726 00:37:40,400 --> 00:37:42,600 Speaker 1: By the way. I I know, I brushed past it 727 00:37:42,719 --> 00:37:44,719 Speaker 1: because I don't handle compliments that well. But I do 728 00:37:44,840 --> 00:37:48,400 Speaker 1: appreciate the comment about me metamorphosizing into a butterfly. 729 00:37:49,040 --> 00:37:51,880 Speaker 2: That was a joke. I'm just kidding. 730 00:37:51,880 --> 00:37:53,120 Speaker 1: Well, definitely edit this part. 731 00:37:53,480 --> 00:37:56,080 Speaker 2: No, it was for sure true. I appreciate you appreciating that. 732 00:37:56,680 --> 00:37:59,560 Speaker 1: So did we just come back from from a break? 733 00:37:59,640 --> 00:38:01,359 Speaker 1: Is that here? 734 00:38:01,560 --> 00:38:02,440 Speaker 2: Yeah, that's what's going on. 735 00:38:02,960 --> 00:38:06,160 Speaker 3: But we can wrap it up and talk about caterpillar management, 736 00:38:06,320 --> 00:38:13,040 Speaker 3: because here's the deal. Caterpillars eat leaves, and you know 737 00:38:13,239 --> 00:38:16,080 Speaker 3: they can they can eat garden stuff. If you have 738 00:38:16,160 --> 00:38:19,160 Speaker 3: a garden that you're planting, but it's not that big 739 00:38:19,239 --> 00:38:23,239 Speaker 3: a deal. Like, individual caterpillars are not gonna ravage your 740 00:38:23,280 --> 00:38:27,600 Speaker 3: garden and spoil your garden. If you have big groups 741 00:38:27,719 --> 00:38:33,239 Speaker 3: of those gregarious caterpillars, they can cause problems. But you know, 742 00:38:33,280 --> 00:38:36,759 Speaker 3: if you see caterpillars in your garden, don't like, don't 743 00:38:36,800 --> 00:38:38,919 Speaker 3: overreact and be like, I gotta, I gotta start killing 744 00:38:38,960 --> 00:38:43,840 Speaker 3: all these caterpillars. You know, take a breath, assess your problem. 745 00:38:44,239 --> 00:38:46,200 Speaker 3: Are they ravaging your garden or do you just have 746 00:38:46,320 --> 00:38:48,640 Speaker 3: some caterpillars here and there, like because you want those 747 00:38:48,680 --> 00:38:49,800 Speaker 3: butterflies later on, don't you. 748 00:38:50,719 --> 00:38:53,080 Speaker 1: Right, Yeah, definitely, that's a big part. And it's not 749 00:38:53,239 --> 00:38:56,719 Speaker 1: just for their beauty either. Caterpillars and butterflies alike are 750 00:38:56,840 --> 00:39:00,359 Speaker 1: food source for birds, which is sad, but it's part 751 00:39:00,400 --> 00:39:03,040 Speaker 1: of the circle of life, I guess. So that's one 752 00:39:03,120 --> 00:39:08,200 Speaker 1: reason alone. They're also probably even more important for your garden. Pollinators, yeah, 753 00:39:08,920 --> 00:39:12,799 Speaker 1: big time pollinators. There was a dead milkman joke in there. 754 00:39:12,840 --> 00:39:16,640 Speaker 1: I couldn't quite I couldn't quite make it. But so 755 00:39:16,719 --> 00:39:21,520 Speaker 1: they pollinate their food source, and most caterpillars, although all 756 00:39:21,600 --> 00:39:23,480 Speaker 1: of them eat leaves and again like we said they're 757 00:39:23,480 --> 00:39:27,600 Speaker 1: eating machines. The amount of damage they're doing is really 758 00:39:27,680 --> 00:39:30,960 Speaker 1: kind of pales in comparison to the benefits you get 759 00:39:31,000 --> 00:39:33,239 Speaker 1: from having them in your ecosystem. So for the most part, 760 00:39:33,280 --> 00:39:34,400 Speaker 1: you want to just leave them alone. 761 00:39:34,800 --> 00:39:35,000 Speaker 2: Yeah. 762 00:39:35,040 --> 00:39:37,120 Speaker 3: I mean, there's a whole section if you're interested on 763 00:39:37,400 --> 00:39:41,239 Speaker 3: how to kill and get rid of caterpillars at HowStuffWorks 764 00:39:41,239 --> 00:39:43,560 Speaker 3: dot com in this article, but I don't even feel 765 00:39:43,600 --> 00:39:45,720 Speaker 3: like talking about it, to be honest. 766 00:39:46,200 --> 00:39:49,000 Speaker 1: Well, let's talk about gregarious caterpillars, because those are the 767 00:39:49,040 --> 00:39:53,000 Speaker 1: ones that really are problematic. They can on a bad 768 00:39:53,120 --> 00:39:56,560 Speaker 1: year or a good year for the gregarious caterpillars, they 769 00:39:56,640 --> 00:40:00,800 Speaker 1: can consume up to a quarter of the leaves in 770 00:40:00,880 --> 00:40:04,879 Speaker 1: a forest. Yeah, and they if they attack the same 771 00:40:05,000 --> 00:40:08,319 Speaker 1: tree enough times, they'll kill a tree. So gypsy moth 772 00:40:08,480 --> 00:40:11,520 Speaker 1: caterpillars are gregarious, and they're well known for killing trees 773 00:40:11,640 --> 00:40:13,880 Speaker 1: just from eating the leaves off of it. That's how 774 00:40:13,960 --> 00:40:16,600 Speaker 1: much damage they can do. And they can also harm 775 00:40:16,680 --> 00:40:21,239 Speaker 1: crops too, So gregarious caterpillars you actually probably do want 776 00:40:21,280 --> 00:40:23,200 Speaker 1: to get rid of if you come across it. But 777 00:40:23,320 --> 00:40:25,760 Speaker 1: the key is prevention. Like you look for the eggs 778 00:40:25,920 --> 00:40:28,680 Speaker 1: which form a ring around like a tree branch and 779 00:40:29,000 --> 00:40:31,719 Speaker 1: take care of those then, like, don't try to deal 780 00:40:31,800 --> 00:40:33,680 Speaker 1: with them later, it's going to be too late. You 781 00:40:33,760 --> 00:40:37,480 Speaker 1: want to be proactive. They say the best defense is 782 00:40:38,560 --> 00:40:41,000 Speaker 1: shooting your poop five feet away from you. 783 00:40:41,160 --> 00:40:41,319 Speaker 2: Yeah. 784 00:40:41,360 --> 00:40:43,160 Speaker 3: I mean, I guess if you're in forest management or 785 00:40:43,160 --> 00:40:46,040 Speaker 3: if you're a farmer and it has like a literal 786 00:40:46,080 --> 00:40:48,440 Speaker 3: effect on your crops and your forests and stuff like that, 787 00:40:48,920 --> 00:40:52,400 Speaker 3: they're out there, you know, burning tents and nests and 788 00:40:52,480 --> 00:40:55,759 Speaker 3: things like that. But that's not something you should go 789 00:40:55,880 --> 00:40:57,839 Speaker 3: out and try to do because that's you don't want 790 00:40:57,880 --> 00:40:59,600 Speaker 3: to catch something on a tree on fire. 791 00:41:01,880 --> 00:41:02,600 Speaker 2: Just not a good idea. 792 00:41:02,600 --> 00:41:04,359 Speaker 1: But can you just see somebody trying to get rid 793 00:41:04,360 --> 00:41:06,640 Speaker 1: of caterpillars and be like, yeah, oh and you just 794 00:41:06,719 --> 00:41:07,839 Speaker 1: started a wildfire? 795 00:41:08,280 --> 00:41:10,879 Speaker 2: Yes I can't, I really can. 796 00:41:12,680 --> 00:41:15,239 Speaker 1: It's hilarious if you think about it. It's so doode 797 00:41:15,280 --> 00:41:15,440 Speaker 1: it is. 798 00:41:17,120 --> 00:41:19,280 Speaker 2: Should we finish up with the assassin caterpillar? 799 00:41:19,560 --> 00:41:19,680 Speaker 3: Well? 800 00:41:19,760 --> 00:41:21,359 Speaker 1: Can I talk about one more thing you don't want 801 00:41:21,400 --> 00:41:23,160 Speaker 1: to talk about just for a second, because I think 802 00:41:23,200 --> 00:41:26,560 Speaker 1: it's kind of nuts as well. Okay, there's a bacterium 803 00:41:26,680 --> 00:41:31,160 Speaker 1: called Basillis thrying inis. I believe et for short, this 804 00:41:31,320 --> 00:41:34,279 Speaker 1: is a bacteria that people purposely introduce as a as 805 00:41:34,360 --> 00:41:38,120 Speaker 1: a caterpillar control measure, and it goes in and created 806 00:41:38,920 --> 00:41:41,800 Speaker 1: produces holes in the caterpillars gut and leads to sepsis, 807 00:41:41,880 --> 00:41:43,759 Speaker 1: and it dies a painful death a few days after 808 00:41:43,960 --> 00:41:48,320 Speaker 1: being infected. This is considered organic gardening. The problem is 809 00:41:48,400 --> 00:41:51,719 Speaker 1: it doesn't just target caterpillars you don't want it. It 810 00:41:51,800 --> 00:41:55,000 Speaker 1: targets all caterpillars. And it's also a pretty terrible way 811 00:41:55,040 --> 00:41:58,319 Speaker 1: to die. So I'm I think I'm with you, Chuck Man. 812 00:41:58,360 --> 00:42:01,160 Speaker 1: I think you just you say the caterpillars are here 813 00:42:01,200 --> 00:42:02,920 Speaker 1: to stay as long as they're not gregarious. I'm just 814 00:42:03,000 --> 00:42:06,440 Speaker 1: gonna let them live and let live. Yeah, Okay, I 815 00:42:06,560 --> 00:42:08,440 Speaker 1: just wanted to get on that soapbox for a sing. 816 00:42:08,560 --> 00:42:11,680 Speaker 3: Yeah, I'm with you. So I mentioned the assassin caterpillar. 817 00:42:12,280 --> 00:42:17,160 Speaker 3: This is the Linomia obliqua, or the giant silkworm moth, 818 00:42:18,200 --> 00:42:21,759 Speaker 3: or the assassin caterpillar. It is the deadliest caterpillar in 819 00:42:21,800 --> 00:42:26,880 Speaker 3: the world and there have been supposedly several hundred people 820 00:42:27,239 --> 00:42:31,600 Speaker 3: in South America that have died from the toxin injected 821 00:42:32,239 --> 00:42:33,440 Speaker 3: from this caterpillar. 822 00:42:33,560 --> 00:42:34,760 Speaker 1: Quills from the sette. 823 00:42:35,280 --> 00:42:38,600 Speaker 3: Yeah, I think it takes a lot, like even if 824 00:42:38,680 --> 00:42:42,320 Speaker 3: one of them, you know, injected some toxin into you, 825 00:42:42,400 --> 00:42:44,560 Speaker 3: you're going to be uncomfortable and it probably won't feel great. 826 00:42:44,600 --> 00:42:46,800 Speaker 3: But I think you need to get like, you know, 827 00:42:48,200 --> 00:42:50,920 Speaker 3: twenty to one hundred times that to actually kill you. 828 00:42:51,200 --> 00:42:52,799 Speaker 3: Yet it still happens, Yeah, it does. 829 00:42:52,920 --> 00:42:57,000 Speaker 1: Apparently it's responsible for five hundred deaths around South America 830 00:42:57,080 --> 00:43:00,000 Speaker 1: I think total, like in all time as far as 831 00:43:00,200 --> 00:43:03,160 Speaker 1: documented goes. Yeah, it takes a lot, like I think 832 00:43:03,239 --> 00:43:05,960 Speaker 1: twenty to one hundred times to kill you. But the 833 00:43:06,040 --> 00:43:08,560 Speaker 1: way that it kills you is it's an anticoagulant, a 834 00:43:08,719 --> 00:43:12,400 Speaker 1: very powerful one, and you die of internal bleeding essentially. 835 00:43:12,719 --> 00:43:14,320 Speaker 2: Yeah, it's it's a blood thinner. 836 00:43:15,120 --> 00:43:19,280 Speaker 1: Yeah, and that's that actually is being studied, the toxins 837 00:43:19,360 --> 00:43:24,160 Speaker 1: in that particular caterpillar being studied for its usefulness in biomedicine. 838 00:43:24,320 --> 00:43:26,480 Speaker 3: Yeah, I think they're only what is it, there's like 839 00:43:26,600 --> 00:43:31,680 Speaker 3: thirty two species of Linomia, but only two of those 840 00:43:32,400 --> 00:43:37,040 Speaker 3: have that blood thinner venom, the obliqua and then the achillis. 841 00:43:37,400 --> 00:43:39,279 Speaker 1: But the rest will still sting you. It's just not 842 00:43:39,360 --> 00:43:42,400 Speaker 1: going to kill you. It'll still hurt that's South America. 843 00:43:42,600 --> 00:43:44,719 Speaker 1: In North America, the biggest one we have is the 844 00:43:44,840 --> 00:43:53,080 Speaker 1: puss caterpillar. Puss megalopige upper cularis the southern flannel moth, 845 00:43:53,800 --> 00:43:57,879 Speaker 1: and just accidentally brushing it can cause excruciating pain I've seen. 846 00:43:58,000 --> 00:44:01,960 Speaker 1: So just be careful. Admire caterpillars with your eyes, not 847 00:44:02,120 --> 00:44:02,760 Speaker 1: with your hands. 848 00:44:03,400 --> 00:44:05,839 Speaker 2: Yeah. I guess I got lucky as a kid by 849 00:44:06,040 --> 00:44:08,080 Speaker 2: just letting them crawl on me for a minute. But yeah, 850 00:44:08,320 --> 00:44:09,799 Speaker 2: I I never felt that sting. 851 00:44:11,160 --> 00:44:14,799 Speaker 1: There's one other thing too, The eastern tent caterpillars are problematic, 852 00:44:14,960 --> 00:44:18,399 Speaker 1: especially in places like Kentucky, because they cause what's called 853 00:44:18,480 --> 00:44:23,800 Speaker 1: mayor reproductive loss syndrome, where just I think fifty grams 854 00:44:23,800 --> 00:44:26,759 Speaker 1: which is a tenth of a pound of these caterpillars 855 00:44:27,200 --> 00:44:29,840 Speaker 1: ingested by a horse while it's foraging can cause it 856 00:44:29,960 --> 00:44:36,040 Speaker 1: to lose its fetus, have a stillborn berth, all sorts 857 00:44:36,080 --> 00:44:37,840 Speaker 1: of crazy stuff, so much so that it has a 858 00:44:37,880 --> 00:44:40,839 Speaker 1: whole syndrome named after and it's just for eating these caterpillars. 859 00:44:41,520 --> 00:44:43,040 Speaker 1: Oh wow, isn't that crazy? 860 00:44:43,520 --> 00:44:44,799 Speaker 2: That is this is a good one. 861 00:44:44,960 --> 00:44:47,600 Speaker 1: I thought you'd like that. Yeah, caterpillars are great. I 862 00:44:47,600 --> 00:44:49,759 Speaker 1: think we should do a two parter with butterflies. 863 00:44:50,280 --> 00:44:54,359 Speaker 2: Oh should we sure? I think Tracy wrote that one too. 864 00:44:55,520 --> 00:44:57,040 Speaker 1: Okay, I say we get on a bench. 865 00:44:57,320 --> 00:44:59,080 Speaker 2: I was going to suggest that, but then I thought, 866 00:44:59,239 --> 00:44:59,799 Speaker 2: is that too much? 867 00:45:00,280 --> 00:45:03,160 Speaker 1: I don't know, I don't know. I guess they don't 868 00:45:03,200 --> 00:45:04,520 Speaker 1: have to come out back to back. They can be 869 00:45:04,600 --> 00:45:05,520 Speaker 1: companion pieces. 870 00:45:05,560 --> 00:45:07,120 Speaker 3: How about that we're back to back and then we 871 00:45:07,160 --> 00:45:09,160 Speaker 3: can skip the metamorphosis marsa. 872 00:45:10,560 --> 00:45:13,480 Speaker 1: Well, while we're figuring that out, I say, everybody, it's 873 00:45:13,520 --> 00:45:14,480 Speaker 1: time for listener mail. 874 00:45:16,360 --> 00:45:18,440 Speaker 3: I'm going to call this stuff you should know acrossy. 875 00:45:19,239 --> 00:45:22,839 Speaker 3: I was very excited because one of our listeners, well, 876 00:45:22,880 --> 00:45:23,480 Speaker 3: I'll just read it. 877 00:45:23,760 --> 00:45:24,680 Speaker 2: I'll let you hang on that. 878 00:45:24,680 --> 00:45:25,200 Speaker 1: For a second. 879 00:45:25,640 --> 00:45:28,799 Speaker 3: Hey, guys, When my wife Katie and I were dating, 880 00:45:28,880 --> 00:45:31,080 Speaker 3: we would meet up at lunch to do the daily 881 00:45:31,160 --> 00:45:31,920 Speaker 3: crossword together. 882 00:45:32,320 --> 00:45:34,160 Speaker 2: I proposed to her twenty years ago using a. 883 00:45:34,160 --> 00:45:38,400 Speaker 3: Crossword I constructed myself, and years later, it's not only crosswords, 884 00:45:38,400 --> 00:45:41,560 Speaker 3: but stuff you should know.
