WEBVTT - Shoo Fly Don't Bother Me 0:00:00.280 --> 0:00:02.840 Brought to you by the reinvented two thousand twelve camera. 0:00:03.160 --> 0:00:07.560 It's ready. Are you welcome to Stuff you should know 0:00:08.160 --> 0:00:23.560 from House Stuff Works dot com? Yeah, wait your house 0:00:24.760 --> 0:00:57.200 it's a good y Hey, and welcome to the podcast. 0:00:57.360 --> 0:01:00.160 This is Josh. That's Chuck. This is Stuffy should know. 0:01:00.640 --> 0:01:03.080 How do you smell? Chuck? Was that at the other 0:01:03.120 --> 0:01:07.640 room this morning? So? How how are you holding up? Well? 0:01:07.680 --> 0:01:10.080 This is we got a good three and a half 0:01:10.120 --> 0:01:15.160 beat between us. Fine, um, you heard this is a 0:01:15.920 --> 0:01:21.280 non usual opening for this podcast. You didn't hear, but 0:01:21.720 --> 0:01:25.880 I heard you did. Okay, Okay, So that's the that's 0:01:25.959 --> 0:01:30.600 the last few seconds. I guess of the Fly, the 0:01:30.640 --> 0:01:34.360 original nineteen fifty eight version starring Vincent Price, and that 0:01:34.640 --> 0:01:40.600 is the the inventor named Seth Brendle, who um brindle fly, Yeah, 0:01:40.880 --> 0:01:43.760 who has converted himself into a fly. Well switched heads 0:01:43.959 --> 0:01:47.960 with the fly, right, switched bodies, I guess. And now 0:01:47.960 --> 0:01:50.320 he's a tiny little fly man who's being attacked by 0:01:50.320 --> 0:01:52.440 a spider on the spider web. You know, I just 0:01:52.480 --> 0:01:55.960 saw the Cromeberg version a couple of months ago. I 0:01:56.000 --> 0:01:58.680 think I told you that. Yeah, it holds up the 0:01:58.680 --> 0:02:03.240 first time. Yeah, it's that I don't understand why um oh, 0:02:03.280 --> 0:02:07.840 what is his name, the main guy, gold bloom. I 0:02:07.880 --> 0:02:13.920 don't understand why Jeff Goldbloom um decided to add I 0:02:13.919 --> 0:02:17.280 guess it's a kind of like sexy arrogance to his 0:02:17.400 --> 0:02:20.840 character because it came off weird. That's just the gold 0:02:21.440 --> 0:02:24.440 he can do, I guess. So, man, the he brings 0:02:24.440 --> 0:02:28.080 that to everything he does. He's tripping with it. So chuck, 0:02:28.120 --> 0:02:31.000 we uh. We played that part of the fly not 0:02:31.120 --> 0:02:33.480 so much because we could, although that was a large 0:02:33.520 --> 0:02:38.560 part of it, but because we can explain what is 0:02:38.600 --> 0:02:41.600 on that little fly body. Now, that's right. We've read 0:02:41.680 --> 0:02:45.480 how flies work, and specifically how house flies work by 0:02:45.639 --> 0:02:49.120 stuff to blow your mind. Robert Lamb's been popping up 0:02:49.120 --> 0:02:52.359 a lot lately, hasn't he? Who Robert's work? Yeah? Yeah, 0:02:52.919 --> 0:02:55.920 good stuff, And he just kind of pops into the 0:02:55.960 --> 0:03:00.400 cubicles and says, hey, how's it going a lot lately? Yeah? Yeah. 0:03:00.480 --> 0:03:03.360 The housefly josh, um, if you're if you live in 0:03:03.360 --> 0:03:06.280 a house and you're flies flying around, you got about 0:03:06.280 --> 0:03:11.320 a nine chance that that is an actual Musca domestica. Yeah, 0:03:12.600 --> 0:03:14.919 that's the that's the houseflies name. That's right. There's not 0:03:15.040 --> 0:03:19.079 some other more exotic name. It is on all um 0:03:19.240 --> 0:03:22.800 initial appearances, one of the more mundane bugs ever. But 0:03:22.960 --> 0:03:26.359 it's actually pretty interesting if you ask me, and disgusting 0:03:26.400 --> 0:03:30.440 because they carry lots of diseases like typhoid, fever and 0:03:30.480 --> 0:03:34.040 sam and ella and leprosy and cholera. Isn't that crazy? 0:03:34.080 --> 0:03:38.280 They carry leprosy and testinal worms. Well, I knew that 0:03:38.400 --> 0:03:40.840 bacteria that can lead to dysentery. I didn't know that 0:03:40.880 --> 0:03:43.880 they could, Uh, they could carry leprosy, though I didn't either. 0:03:44.240 --> 0:03:48.320 You know, I always equate leprosy with nudism because they 0:03:48.360 --> 0:03:52.560 both they both live in colonies. Yeah, I always think 0:03:52.600 --> 0:03:54.480 of leprosy when I think of lepricy. I think of 0:03:54.520 --> 0:03:57.160 the Bible, because growing up in churches where I heard 0:03:57.160 --> 0:04:00.680 about lepro colonies and leprosy and leprity being healed and 0:04:00.720 --> 0:04:03.480 all that. Exactly have you ever seen the fog the 0:04:03.560 --> 0:04:10.040 second one? I guess for the fog too? Was there 0:04:10.040 --> 0:04:12.120 a fog too? I don't know. I mean John Carpenter 0:04:12.240 --> 0:04:14.560 the original fog, I think, right, this is the remake 0:04:15.320 --> 0:04:18.920 where the people attacking were lepers who were turned away 0:04:19.240 --> 0:04:21.520 and now their ghosts have come back for Vengeance. I 0:04:21.600 --> 0:04:23.440 think that was the original as well. It wasn't. I 0:04:23.480 --> 0:04:25.200 didn't realize there were lepers. I thought they were like 0:04:25.240 --> 0:04:27.760 pirates that have been across or something. Cheez. We need 0:04:27.800 --> 0:04:29.720 to get her act together. And that's such a good movie, 0:04:29.800 --> 0:04:31.680 the first one. Yeah, I'll check it out. I just 0:04:31.680 --> 0:04:34.719 watched the thing last night. Oh that's a great one too. Yeah. 0:04:35.400 --> 0:04:38.880 And I had a fairly voracious Alien versus the Thing 0:04:39.920 --> 0:04:44.160 comments on I saw people get into that. I definitely 0:04:44.240 --> 0:04:48.680 say Alien is bad or but the thing is more disgusting, 0:04:48.800 --> 0:04:51.520 a little more twisted. Yeah, alright, this has been a 0:04:51.560 --> 0:04:55.279 long setup. Flies huh so chuck, um, We've we've got 0:04:55.400 --> 0:05:01.480 down that they spread disease, right potentially. Um. One of 0:05:01.520 --> 0:05:03.520 the things that kind of cropped up while I was 0:05:03.560 --> 0:05:07.279 reading this is it was kind of an expansion of 0:05:07.320 --> 0:05:10.599 everything I'd always knew about flies. Yeah, we all know 0:05:10.600 --> 0:05:13.120 a little bit, which I find very reassuring. You know, 0:05:13.240 --> 0:05:16.520 it's not like quantum suicide, where it's like everything you 0:05:16.560 --> 0:05:19.480 think you know is just completely unreal and just go 0:05:19.520 --> 0:05:22.760 ahead and stop thinking. Now. This is like, yes, you 0:05:22.839 --> 0:05:26.760 understand house flies, and here is some more information about them. 0:05:26.880 --> 0:05:29.440 So I guess kind of this is almost like an 0:05:29.440 --> 0:05:34.080 elementary school episode, which I find I find comforting and 0:05:34.080 --> 0:05:37.960 reassuring to let's talk about fly anatomy, house fly anatomy, 0:05:38.000 --> 0:05:40.880 and if I accidentally say fly, if you accidentally say fly, 0:05:41.200 --> 0:05:43.800 we mean house fly specifically, right, that's right, Oh, And 0:05:43.880 --> 0:05:47.320 dispersed throughout the podcast, we'll have fly facts that sounds 0:05:47.360 --> 0:05:51.200 like this, So when you hear that, it's gonna be 0:05:51.240 --> 0:05:53.800 a new fly fact. So, Josh, if you're talking a 0:05:53.800 --> 0:05:58.000 housefly body, it's like a lot of insects. It's got 0:05:58.040 --> 0:06:01.280 an exo skeleton made of kitan, and it's got three 0:06:01.320 --> 0:06:03.560 sections to the body. You got the head, you got 0:06:03.560 --> 0:06:07.240 the thorax, you got the abdomen. And as everyone knows, 0:06:08.200 --> 0:06:10.320 this is the this is actually isn't a fly fact, 0:06:10.400 --> 0:06:13.760 so no buzz, but it is effect, but it's not 0:06:13.800 --> 0:06:16.480 one of our fly facts. So every jingle, no jingle. 0:06:16.560 --> 0:06:18.920 Everyone knows that the fly has all those tiny, little 0:06:18.920 --> 0:06:21.320 bitty eyes, and like you said, it's reassuring to know 0:06:21.400 --> 0:06:24.520 that's exactly what they are. There two common eyes divided 0:06:24.600 --> 0:06:28.599 up into three to six thousand simple eze yes, and 0:06:28.640 --> 0:06:30.640 it's like a bunch of little video monitors because they 0:06:30.640 --> 0:06:35.640 can't focus on one little thing in particular. It's like 0:06:35.640 --> 0:06:39.320 a mosaic, right, but I also got the impression that 0:06:39.680 --> 0:06:43.040 it's like a mosaic. But each little eye is kind 0:06:43.080 --> 0:06:47.039 of its own. It's representative of the physical grid. It 0:06:47.080 --> 0:06:50.480 makes a grid of its physical environment. Right. So I 0:06:51.040 --> 0:06:53.520 wonder if the flies like, oh, there's a movement in sector, 0:06:54.720 --> 0:06:56.520 what I wonder and like, I go focus on that 0:06:56.560 --> 0:06:59.640 one simple eye to see that, you know a piece 0:06:59.640 --> 0:07:01.240 of poo on the ground that I need to go, 0:07:01.520 --> 0:07:05.240 you know, wattle through, or there's a human um who's 0:07:05.440 --> 0:07:07.560 coming towards me or something. And of course by sector 0:07:07.640 --> 0:07:12.280 ninety G, I meant sector three thousand to six thousand G. Yeah. 0:07:12.600 --> 0:07:15.800 So those are the eyes, and they are also a 0:07:15.840 --> 0:07:20.720 couple of little um I think three ocel eyes or 0:07:20.840 --> 0:07:25.960 if you're in Itali in Italy, and they are between 0:07:26.000 --> 0:07:27.880 the two compound eyes. And that's sort of like a 0:07:27.880 --> 0:07:32.240 compass that keep the fly oriented and ideally flying towards 0:07:32.240 --> 0:07:35.480 the sun. Okay, So I think that this should be 0:07:35.520 --> 0:07:41.320 the first fly fact. All right, let's do it, okay, 0:07:41.440 --> 0:07:45.320 uh chuck. The reason house flies are commonly found kind 0:07:45.320 --> 0:07:50.119 of flittering against a window because they're stupid, No, that's 0:07:50.240 --> 0:07:54.280 a fly myth. The fly fact is that they're oh 0:07:54.560 --> 0:07:58.680 ocelli or ocelli. The to simplize the act as a 0:07:58.720 --> 0:08:02.760 compass orient themselves upward by finding the sunlight. They're all 0:08:02.840 --> 0:08:05.800 constantly searching for sunlight, which is why they always go 0:08:05.920 --> 0:08:08.800 to a window or a bugs ever. That was fly 0:08:08.960 --> 0:08:12.880 back number one, all right, I like it on the head, Josh, 0:08:12.920 --> 0:08:14.760 which is where a lot of the action takes place 0:08:14.760 --> 0:08:17.640 with a fly. Um. They get their sense of smell 0:08:17.800 --> 0:08:22.360 from their antennae right there. For tasting and eating. They 0:08:22.400 --> 0:08:26.200 have a probiscus, which is a little plunger like thing 0:08:26.280 --> 0:08:29.040 that sticks out from the bottom of its mouth and 0:08:29.200 --> 0:08:31.720 I'm sorry, the bottom of the head um. They have 0:08:31.760 --> 0:08:35.680 little feelers, two of these, and their max maxillary palps. 0:08:36.320 --> 0:08:40.040 Yeah yeah, and then they are the tasters. And at 0:08:40.040 --> 0:08:43.120 the end of the probiscus you have the labellum, which 0:08:43.200 --> 0:08:47.160 is um. Is that the mouth, the little spongey part. Yeah, 0:08:47.320 --> 0:08:50.480 it's it's like a sponge mouth like it's not like 0:08:50.520 --> 0:08:53.480 an open mouth that you think of. It's like a 0:08:53.559 --> 0:08:56.760 sponge on the end of the pro proboscis where you 0:08:56.880 --> 0:09:01.040 just suck. That's a probiscus didn't they it's close proboscus. 0:09:01.320 --> 0:09:03.920 Sorry about that. No, it goes either way, and that 0:09:04.000 --> 0:09:09.200 always makes me think of adaptation. Chris Cooper's character talks 0:09:09.240 --> 0:09:12.240 about the probiscus of the orchid. Oh yeah, Jerry's and 0:09:12.280 --> 0:09:16.480 they're just saying, yes, it's really weird. Apparently she's um 0:09:16.520 --> 0:09:19.880 guest starring in this episode. She's paying attention for the 0:09:19.920 --> 0:09:23.080 first time in weeks. So, um, chuck, there's a huge, 0:09:23.240 --> 0:09:27.480 huge little thing that you You pointed out that um uh, 0:09:27.880 --> 0:09:32.319 the labellum. Yes, the spongy mouth doesn't allow solid food 0:09:32.320 --> 0:09:34.160 in and we're gonna get to that in a minute, 0:09:34.160 --> 0:09:36.760 but just keep that in mind. That's fly foreshadowing, not 0:09:36.840 --> 0:09:39.640 a fly fact. But we've come to what I think 0:09:39.760 --> 0:09:41.880 is fly fact number two. Don't you are you going 0:09:41.960 --> 0:09:45.240 with the biting? Yeah, the biting, Okay, fly fact number two. 0:09:48.200 --> 0:09:50.840 Houseflies do not bite. If you get bitten by a fly, 0:09:51.240 --> 0:09:53.240 it was not a houseflowd on housewives. Might be a 0:09:53.280 --> 0:09:55.400 horse fly, and you know those in the summertime when 0:09:55.400 --> 0:09:57.880 you're in the pool, the land on your head and 0:09:58.320 --> 0:10:00.360 bite the tar out of you. Or it might have 0:10:00.400 --> 0:10:03.440 been your little sibling, brothers, sister. That's true and what 0:10:03.480 --> 0:10:07.880 other list another one stable flies, which are yeah, yeah, 0:10:07.880 --> 0:10:11.360 horseflies there there. They kind of take care of all 0:10:11.400 --> 0:10:13.640 the horses at once, where a horse flies just like 0:10:13.679 --> 0:10:16.320 I just want this one horse. That's my take on it, 0:10:16.360 --> 0:10:19.880 all right, So that's fly fact too, So chuck, Um, 0:10:20.000 --> 0:10:22.520 we are onto wings now, which isn't necessarily a fly 0:10:22.600 --> 0:10:26.319 fact because it's so essential. Right back in ancient times, 0:10:26.760 --> 0:10:30.800 which was up to sixty million years ago, as I understand, Um, 0:10:30.800 --> 0:10:34.720 that's how long houseflies have been around. Um, they had 0:10:34.760 --> 0:10:38.240 two sets, two full sets of wings, and nowadays in 0:10:38.320 --> 0:10:41.240 our modern times, it looks like flies have houseflies have 0:10:41.360 --> 0:10:45.040 one set. That's not necessarily true. Yeah, if you're a 0:10:45.080 --> 0:10:47.880 little jerky kid, a little myoclonic jerk, and you pull 0:10:47.920 --> 0:10:50.920 the wings off of a fly, you probably think you're 0:10:50.920 --> 0:10:54.040 just pulling off too. Yeah, and you may be, because 0:10:54.040 --> 0:10:56.520 those are the large ones. But there's little tiny guys 0:10:56.600 --> 0:10:59.679 under there, and they're called halters, right, and the halters 0:11:00.000 --> 0:11:02.960 where actually if you if you pull the halter off, 0:11:03.280 --> 0:11:06.400 these little tiny wings um that are underneath or above 0:11:06.920 --> 0:11:09.559 I think they're underneath. They're underneath the big wings um. 0:11:09.640 --> 0:11:13.360 They allow they basically allow the fly to move quickly 0:11:13.480 --> 0:11:19.480 in the air right to um to maintain balance a 0:11:19.600 --> 0:11:23.600 direct direction hover, yes, um. And so if you remove 0:11:23.679 --> 0:11:25.400 one of these, it can only go in circles. If 0:11:25.440 --> 0:11:27.960 you remove both of the halters to fly, can't get 0:11:28.520 --> 0:11:30.839 is an airborne at all? Yeah, with those two big wings, 0:11:30.840 --> 0:11:33.640 it still can't fly without his little halters. Ye, it's 0:11:33.640 --> 0:11:37.720 pretty good, but not a fly fact. No, very interesting nonetheless, 0:11:37.760 --> 0:11:40.560 But the the big wings, the large wings that you 0:11:40.600 --> 0:11:42.400 see when you look at a fly, are the ones 0:11:42.440 --> 0:11:44.840 that do the real heavy lifting, right. Yeah, We're talking 0:11:44.880 --> 0:11:49.000 two hundred to three hundred flaps per second, and they 0:11:49.040 --> 0:11:50.560 can go about four and a half miles an hour, 0:11:51.400 --> 0:11:53.800 which I would have assumed they could go faster than 0:11:54.360 --> 0:11:56.160 I can run four and a half miles an hour. 0:11:56.240 --> 0:11:59.280 And it's and I've seen flies zipping by me when 0:11:59.320 --> 0:12:02.480 I'm running. So chuck first, I don't know if you 0:12:02.520 --> 0:12:05.280 said the all of the moving parts, the wings, the legs, 0:12:05.280 --> 0:12:08.120 all this stuff, um, are located in the thorax, right, 0:12:08.480 --> 0:12:10.360 So you get the two sets of wings up top, 0:12:10.360 --> 0:12:14.120 and then below that you have the different legs. And 0:12:14.160 --> 0:12:17.960 the legs are well, they're they're standard legs. They're segmented 0:12:18.000 --> 0:12:21.200 and joined. But the most interesting part for me about 0:12:21.240 --> 0:12:25.559 the fly legs the house fly legs are the tarsi, right, yes, 0:12:25.679 --> 0:12:27.640 which are little tiny hairs on the end of the 0:12:27.720 --> 0:12:31.400 legs that act as pretty much the same thing as 0:12:31.679 --> 0:12:36.079 taste buds do for us. So that's why a fly um, 0:12:36.320 --> 0:12:39.160 that's why it'll land on food. It's not just landing, 0:12:39.679 --> 0:12:42.760 it's tasting to say do I want some of this? 0:12:43.720 --> 0:12:45.760 And most of the time the answers yes yes. And 0:12:45.760 --> 0:12:48.320 we'll get to the gruesome truth of that in a 0:12:48.360 --> 0:12:50.679 moment as well. Right, My favorite part of the legs 0:12:50.679 --> 0:12:53.800 is the pole vili. They are a little moist suction 0:12:53.840 --> 0:12:56.560 pads and they are the little grippers. So that's why 0:12:56.640 --> 0:13:00.440 when you see a fly, uh, jump on a wall, 0:13:00.760 --> 0:13:02.559 fly into a wall, and just all of a sudden 0:13:02.600 --> 0:13:06.520 they're like Spider Man right walking up the wall, little grippers. 0:13:06.880 --> 0:13:11.079 Or that's how Jeff Goldblum did it, with some swad 0:13:11.120 --> 0:13:13.959 of viv as well thrown in there. Uh. And then 0:13:14.000 --> 0:13:17.439 the abdomen they have the key organs which are the 0:13:17.440 --> 0:13:21.600 reproductive organs, and the female the oviposter, and the male 0:13:21.760 --> 0:13:25.360 has the ideas and I actually look at that one 0:13:25.440 --> 0:13:28.840 up nice and that's not how it would have pronounced it. 0:13:28.920 --> 0:13:32.240 But these little uh, little things retract when they're not 0:13:32.240 --> 0:13:33.680 in use, on both the male and the female, so 0:13:33.679 --> 0:13:36.719 they'll stay protected there. That's very aerodynamic. It would be 0:13:36.800 --> 0:13:40.360 very unerodynamic to have the adegus just kind of laughing 0:13:40.360 --> 0:13:43.559 in the wind flies a thing around the house. It's 0:13:43.559 --> 0:13:45.400 like putting the landing gear down a little too soon. 0:13:45.600 --> 0:13:51.000 Write exactly, um, so chuck you you we already foreshadowed 0:13:51.160 --> 0:13:55.199 what's going on with them. The mouth, the sponge mouth, 0:13:55.720 --> 0:14:01.280 the labellum. Yes, um, that it can only up liquids. Well, 0:14:01.400 --> 0:14:04.800 not everything a fly eats is liquid, right, No, not 0:14:04.880 --> 0:14:07.160 if they want to jump on that steak or that 0:14:07.400 --> 0:14:11.600 dog crap or dry blood yea. Um. When a fly 0:14:11.760 --> 0:14:14.640 encounters something, well, first of all, part when when the 0:14:14.800 --> 0:14:18.040 it accepts food into the bellum, it basically sucks it 0:14:18.120 --> 0:14:20.480 straight into the stomach. If it's liquid, it's good to go. 0:14:20.920 --> 0:14:23.480 So when it lands on the food and it finds 0:14:23.520 --> 0:14:27.560 that it can't um, it can't just suck it up, um, 0:14:28.040 --> 0:14:31.320 it basically tries to crumble it with the end of 0:14:31.360 --> 0:14:35.040 its proboscus. Right at that point, it's got tiny little 0:14:35.520 --> 0:14:39.040 it's it's smaller, it's more manageable, and then it pukes 0:14:39.040 --> 0:14:42.880 on it. Yea, that's step two. Everything you've ever heard 0:14:42.880 --> 0:14:46.040 about flies vomiting on you um or your food or 0:14:46.040 --> 0:14:48.480 whatever when they land is absolutely true. Yeah. I thought 0:14:48.480 --> 0:14:50.200 I might have thought that was an old wives talle 0:14:50.240 --> 0:14:52.640 in this article. No, it is true. Um. What the 0:14:52.680 --> 0:14:55.960 fly does is basically spit up saliva and digestive juice 0:14:55.960 --> 0:14:59.680 is onto the little crumbs that it's made using its proboscus, right, um, 0:15:00.040 --> 0:15:06.920 and it sits there for a couple of seconds thinking, 0:15:07.000 --> 0:15:09.680 and then it it tries to slurp it up. Um. 0:15:09.760 --> 0:15:12.440 And Robert makes a really good point in the article 0:15:12.840 --> 0:15:16.400 this sounds extremely disgusting to us, right, sure, but the 0:15:16.400 --> 0:15:20.480 fly isn't doing anything we don't do. When we take 0:15:20.560 --> 0:15:23.680 food into our mouth, we chew it, we masticate it. Right. 0:15:23.960 --> 0:15:26.680 Saliva is attacking it, starting to break it down, and 0:15:26.680 --> 0:15:30.160 then it goes through our esophagus into our stomachs and 0:15:30.560 --> 0:15:34.280 it becomes digested by juices. The flyes just doing the 0:15:34.320 --> 0:15:37.120 same thing, but on the outside of its body because 0:15:37.120 --> 0:15:39.000 it doesn't have teeth, and we have the decency to 0:15:39.080 --> 0:15:41.760 keep it all internal. Right, We don't go into restaurants 0:15:41.760 --> 0:15:44.680 and puke up onto our plate. That just would that 0:15:44.720 --> 0:15:48.640 would be untoward. So if there if the um, if 0:15:48.640 --> 0:15:53.000 this food is kind of in an in between state, um, 0:15:53.080 --> 0:15:55.400 and it's been spent on, vomited on left and it's 0:15:55.440 --> 0:15:58.880 still not quite right, it gets moved to the crop. Right, Yeah, 0:15:59.080 --> 0:16:02.720 I see the what should we call this fly fact? Okay? 0:16:02.760 --> 0:16:08.760 Fly fact? Was this three? Yeah, there's a crop, like 0:16:08.800 --> 0:16:12.040 you said, and instead of just um saying, oh, well 0:16:12.120 --> 0:16:15.840 this this little bit of crumb isn't quite liquid enough, 0:16:15.920 --> 0:16:17.920 let me just go fly to another one, the fly 0:16:18.040 --> 0:16:19.920 is pretty efficient, so they say, actually, let me save 0:16:19.960 --> 0:16:23.720 this for later, stick it down another hole into the crop, 0:16:23.880 --> 0:16:27.680 and in the crop it waits, and then they'll pass 0:16:27.720 --> 0:16:31.120 it back and forth, maybe add a little more digestive juices, 0:16:31.160 --> 0:16:33.160 throw up on it a bit more, and they do 0:16:33.240 --> 0:16:35.960 this until it's ready to be you know, until it's 0:16:36.040 --> 0:16:38.280 liquid ready to go down the shoot. It doesn't waste 0:16:38.320 --> 0:16:41.800 its food. That was fly fact three. Right, Yes, there 0:16:41.880 --> 0:16:44.760 is one thing you know we said that the fly 0:16:45.000 --> 0:16:47.640 is not really doing anything differently than we do to 0:16:47.680 --> 0:16:50.480 our food, is just doing it on the outside. That's 0:16:50.520 --> 0:16:56.040 still horrific and disgusting, because um, not only is the 0:16:56.040 --> 0:17:01.360 the fly carrying possibly leprosy to your sandwich. When it 0:17:01.440 --> 0:17:04.719 throws up on it, it's probably throwing up something at 0:17:04.760 --> 0:17:07.480 just eight which, as you pointed out, could be dog poop, 0:17:07.600 --> 0:17:11.919 could be blood. Uh, could be the you know, poop 0:17:11.960 --> 0:17:15.840 from a leprous dog, something like that. So when you 0:17:15.840 --> 0:17:18.080 you're at a picnic or something and you see that 0:17:18.119 --> 0:17:21.800 fly on your sandy, it's probably and if you see 0:17:21.800 --> 0:17:24.960 it moving his little hands around, it's vomiting disease on 0:17:25.000 --> 0:17:27.919 your food. It's what it's doing, right, exactly, Potentially disease, 0:17:28.160 --> 0:17:32.440 not always no. And plus you don't underestimate the human 0:17:32.440 --> 0:17:34.639 immune system. I mean, we all have white blood cells, 0:17:34.680 --> 0:17:36.520 you know, we all, we all can mount a pretty 0:17:36.560 --> 0:17:39.359 decent defense unless we have some sort of immuno deficiency. 0:17:39.760 --> 0:17:41.720 And if we do have that, then they were probably 0:17:41.720 --> 0:17:44.399 in some sort of treatment for it. So for the 0:17:44.400 --> 0:17:46.639 most part, I mean, it is gross. But you know, 0:17:47.040 --> 0:17:49.560 I think in in modern times where we got the 0:17:49.600 --> 0:17:53.480 flies under control at least you know here in the West. Yes, Um, 0:17:53.640 --> 0:17:57.000 for now, until the apocalypse comes the Rise of the 0:17:57.000 --> 0:18:00.760 fly right, Um, do you remember of that part in 0:18:00.960 --> 0:18:05.080 Amityville Horror The priest is like he's covered in flies 0:18:05.200 --> 0:18:09.400 and starts sweating and was that Rod Starker Huh yeah, 0:18:09.640 --> 0:18:12.840 nice good. I would have been so out of there, 0:18:13.280 --> 0:18:16.920 um chuck. Yes, we talked about their sexy bits already. 0:18:17.400 --> 0:18:19.400 What do they do with them? What's the fly family? 0:18:19.480 --> 0:18:23.880 Like a fly family? Josh is like many insect families. 0:18:23.920 --> 0:18:27.400 They man will chase down a female and impregnate her 0:18:27.840 --> 0:18:30.600 and it happens really quick. She's ready to lay her eggs. 0:18:31.280 --> 0:18:35.120 Toot sweet and uh, they don't stick together after they mate, 0:18:35.160 --> 0:18:38.439 they separate and the and the mother doesn't even guard 0:18:38.480 --> 0:18:42.440 the eggs like a lot of species do. One night 0:18:42.480 --> 0:18:44.879 love affair. Yeah, and she basically dumps the eggs and 0:18:44.920 --> 0:18:46.639 what she deems to be a safe place and she's like, 0:18:46.680 --> 0:18:49.040 I'm out of here. It's one night stand followed in 0:18:49.119 --> 0:18:51.520 child abandonment. And how many eggs is it? Later time? 0:18:51.560 --> 0:18:54.399 Did we get that up to nine? Over the life 0:18:54.400 --> 0:18:57.320 cycle of a fly? Okay, in a life cycle, I 0:18:57.359 --> 0:18:59.479 think they said the average lifesman is about three weeks, 0:18:59.560 --> 0:19:02.360 but it could be three months. Yeah. I don't think 0:19:02.359 --> 0:19:05.480 a fly can live physically beyond three months. But yeah, 0:19:05.480 --> 0:19:08.880 the average lifespan and reality because of fly swatters and 0:19:08.920 --> 0:19:12.040 things like that. Um is like twenty one days. I 0:19:12.119 --> 0:19:15.480 think he said. Yeah. So the life cycle um is 0:19:15.520 --> 0:19:18.240 a lot like most insects. It's got the egg and 0:19:18.280 --> 0:19:22.560 then the larva, then the pupa, then the adult. Warm 0:19:22.600 --> 0:19:25.080 summertime is optimal. It takes about seven to ten days 0:19:25.600 --> 0:19:28.400 to go from egg to adult. And they go through 0:19:28.520 --> 0:19:31.639 I think three molten stages. Uh, the little maggot student, 0:19:31.720 --> 0:19:33.679 they see, you know this, you know all this. You 0:19:33.800 --> 0:19:38.080 learn this in school. Didn't it nice to know this? Yeah? 0:19:38.359 --> 0:19:41.640 Very nice? So chuck um with the maggots. The first 0:19:41.680 --> 0:19:43.919 stage of the most interesting stage. We've arrived at a 0:19:43.960 --> 0:19:49.399 story that I have. Oh boy, when I was in college, Um, 0:19:49.600 --> 0:19:54.040 cooked steak through cooked steak and really actually, now they 0:19:54.040 --> 0:19:56.480 think about it, I guess I've probably trimmed some raw 0:19:56.800 --> 0:20:00.440 meat off and put it in the guard bridge can, 0:20:00.680 --> 0:20:03.800 as is normal, a garbage bag in a garbage can, 0:20:03.840 --> 0:20:06.320 the kitchen garbage can. Okay, And I get up the 0:20:06.359 --> 0:20:09.960 next so I'm a normal person. I'm not stick away 0:20:10.160 --> 0:20:15.000 exactly exactly. Um. So I get up the next morning 0:20:15.200 --> 0:20:17.360 and I go into the kitchen and I wonder, why 0:20:17.440 --> 0:20:21.040 is the kitchen floor moving like that? Oh man? And 0:20:21.200 --> 0:20:23.760 I kind of followed the floor as it went up 0:20:23.880 --> 0:20:27.400 the garbage can and into it, and I realized that 0:20:27.640 --> 0:20:30.240 my kitchen floor, it's a small kitchen, granted, but my 0:20:30.320 --> 0:20:34.240 kitchen floor was covered in a living layer of maggots 0:20:34.400 --> 0:20:38.040 the whole thing, the whole thing. So I'm like, I've 0:20:38.080 --> 0:20:39.479 got to get rid of these. What how do you 0:20:39.520 --> 0:20:45.119 take care of a maggot infestation? And I tried bleach first, 0:20:45.560 --> 0:20:49.280 did nothing to him, didn't even slow down one of them. Really, 0:20:49.720 --> 0:20:54.560 I ended up having to walk all over them. Well that, yeah, 0:20:54.680 --> 0:20:57.200 that's the old fashioned way. That's that's what I had 0:20:57.200 --> 0:20:59.720 to do. And for I did not actually have a 0:20:59.720 --> 0:21:03.520 floor infestation after that, so I guess I got them all. 0:21:03.840 --> 0:21:07.080 But they make a horrific little popping sound. Did you 0:21:07.119 --> 0:21:10.280 have have like snow shoes or something at least no, 0:21:10.440 --> 0:21:13.280 probably like hiking boots or something. It was an athen 0:21:13.480 --> 0:21:15.520 Why were they all over the floor? Was it from 0:21:15.560 --> 0:21:19.000 the steak it out of the garbage can overnight? Like 0:21:19.000 --> 0:21:22.160 like that? That's frightening, But that I mean that follows 0:21:22.200 --> 0:21:25.240 with um what we know about the housefly life cycle. 0:21:25.400 --> 0:21:29.719 That Larva's hatch um within a day, right, and and 0:21:29.720 --> 0:21:33.159 don't forget Larva and by Larva's I met larva with 0:21:33.200 --> 0:21:37.000 an E on the end um equals maggots breathe out 0:21:37.000 --> 0:21:38.920 of their butt, right, didn't we learn that somewhere else? 0:21:40.000 --> 0:21:42.320 So they never have to stop eating exactly. So they're 0:21:42.359 --> 0:21:46.800 just like this little fleshy worm like thing with the 0:21:46.880 --> 0:21:51.159 hooked mouth that just does nothing but eat. And yeah, 0:21:51.320 --> 0:21:54.000 because they breathe out of their butts and molt like 0:21:54.000 --> 0:21:56.760 I said, three stages, and then the third molten stage, 0:21:56.800 --> 0:21:59.359 you know, it goes uh, it gets a little darker 0:21:59.800 --> 0:22:03.240 and enters the pupa stage and that's the larger protective shell. 0:22:03.640 --> 0:22:07.960 Then it fully develops and outcomes a beautiful butterfly or 0:22:07.960 --> 0:22:12.520 a disgusting house fly like barton the Simpsons. Yeah, and 0:22:12.560 --> 0:22:15.280 how to like what Barton the senses. There's a treehouse 0:22:15.280 --> 0:22:18.520 of Horror where they redid the fly where he's like 0:22:18.560 --> 0:22:22.160 that mindless like the fly with Bart's bodies it's mindless eating. Yeah, 0:22:22.200 --> 0:22:24.600 that was one of the earlier ones. That's a good one. Uh. 0:22:24.640 --> 0:22:27.040 And then they get out of their little shell there 0:22:27.119 --> 0:22:31.440 with a temporary swollen bump because they can't chew to 0:22:31.520 --> 0:22:34.159 get out of an egg or the shell, so they 0:22:34.280 --> 0:22:37.160 they literally use this bump on their head to crack 0:22:37.200 --> 0:22:39.520 their way out, and then after they get out, that 0:22:39.600 --> 0:22:42.440 bump deflates and it just becomes part of the head again. 0:22:42.760 --> 0:22:45.360 I wonder if it's unique to each fly, like they 0:22:45.600 --> 0:22:48.520 can recognize one another from the bump on the head, Like, 0:22:48.680 --> 0:22:50.120 I don't know, and I didn't There wasn't a name 0:22:50.160 --> 0:22:52.560 for that in here either. No, it's just the swollen 0:22:52.600 --> 0:22:58.840 bump alright. Fly fact number four. Yes, so we talked 0:22:58.880 --> 0:23:02.760 about a fly. It can't live longer than three months, 0:23:02.840 --> 0:23:07.119 that's right, That is if it's existing outside of diapause, right, 0:23:07.920 --> 0:23:11.320 Totally fascinating to me. Yes, So diapause is basically like 0:23:11.880 --> 0:23:16.000 suspended animation or hibernation for the fly. Basically, if there's 0:23:16.160 --> 0:23:21.080 no food around um, and there's no predators either, and 0:23:21.080 --> 0:23:23.919 the flies like I'm gonna see what's going on a 0:23:23.960 --> 0:23:27.320 few months from now, the fly can basically shut down 0:23:27.520 --> 0:23:31.280 it's it's life processes to the state where it can 0:23:31.359 --> 0:23:34.880
