WEBVTT 00:00:00.000 --> 00:00:02.779 So usually when you hear a job title, it's a 00:00:02.779 --> 00:00:04.919 guarantee, right? Like if you hire a plumber, 00:00:05.400 --> 00:00:08.419 you expect a human being with a certain set of 00:00:08.419 --> 00:00:11.019 tools, maybe some training, to show up at your 00:00:11.019 --> 00:00:14.720 front door. Right. A title implies a very specific 00:00:14.720 --> 00:00:17.480 singular identity. Exactly. You rely on that 00:00:17.480 --> 00:00:19.679 categorization to know exactly what you're dealing 00:00:19.679 --> 00:00:22.559 with. You wouldn't expect like a raccoon with 00:00:22.559 --> 00:00:25.000 a wrench to be the one fixing your sink. No. 00:00:25.100 --> 00:00:26.899 I mean, that would be terrifying. You expect 00:00:26.899 --> 00:00:28.679 to know their background and how they operate 00:00:28.679 --> 00:00:31.140 based on that one word. Right. OK, let's unpack 00:00:31.140 --> 00:00:33.820 this because when you look at the natural world, 00:00:33.979 --> 00:00:35.840 specifically at certain types of agricultural 00:00:35.840 --> 00:00:38.920 pests, that logic just completely falls apart. 00:00:38.979 --> 00:00:41.119 It really does. We are looking at a biological 00:00:41.119 --> 00:00:43.439 job description today that is currently being 00:00:43.439 --> 00:00:47.140 filled by massive rival syndicates of entirely 00:00:47.140 --> 00:00:49.579 unrelated creatures. Yeah, we are basically looking 00:00:49.579 --> 00:00:52.679 at an index of animals with the exact same common 00:00:52.679 --> 00:00:56.549 name, which It forces us to play detective. For 00:00:56.549 --> 00:00:58.649 sure. We have this term that perfectly describes 00:00:58.649 --> 00:01:00.990 the crime scene, but it gives you absolutely 00:01:00.990 --> 00:01:04.469 zero clues about the actual identity of the criminal. 00:01:04.769 --> 00:01:06.810 And the term we're talking about today in this 00:01:06.810 --> 00:01:11.689 deep dive is twig borer. Yes, the twig borer. 00:01:12.010 --> 00:01:14.250 And you know, based on the Wikipedia excerpt 00:01:14.250 --> 00:01:16.790 we're diving into, this isn't an article about 00:01:16.790 --> 00:01:19.840 a single bug. Not at all. It's a directory, like 00:01:19.840 --> 00:01:22.180 a lineup of suspects that threaten literally 00:01:22.180 --> 00:01:24.939 everything from your morning coffee to your evening 00:01:24.939 --> 00:01:27.159 glass of wine. It's a very extensive list, yeah. 00:01:27.319 --> 00:01:29.680 But before we start, you know, pulling up mugshots, 00:01:29.799 --> 00:01:32.319 we really need to establish the actual modus 00:01:32.319 --> 00:01:35.579 operandi. Like, what actually makes an insect 00:01:35.579 --> 00:01:38.060 a twig borer? And what does this crime scene 00:01:38.060 --> 00:01:40.540 look like? Well, the baseline definition across 00:01:40.540 --> 00:01:43.239 all these different species is that they are 00:01:43.239 --> 00:01:47.299 insects. Specifically, certain beetles and moths. 00:01:47.519 --> 00:01:49.939 OK, beetles and moths. Right. And they chew holes 00:01:49.939 --> 00:01:51.859 into the small branches of trees and shrubs. 00:01:52.500 --> 00:01:54.299 But to really understand the crime scene, you 00:01:54.299 --> 00:01:56.579 have to understand their motive. OK, what's the 00:01:56.579 --> 00:01:58.739 motive? Just food. See, that's the thing. They 00:01:58.739 --> 00:02:00.659 aren't just eating the wood out of hunger and 00:02:00.659 --> 00:02:02.560 moving on. Wait. If they aren't just eating the 00:02:02.560 --> 00:02:04.400 wood, what are they doing inside the branch? 00:02:04.480 --> 00:02:07.060 They are excavating a nursery. Oh, wow. Yeah. 00:02:07.519 --> 00:02:12.240 The adult insect, it bores into the twig. to 00:02:12.240 --> 00:02:14.620 create this safe climate -controlled gallery 00:02:14.620 --> 00:02:17.360 to lay its eggs. OK, so it's moving in. Exactly. 00:02:18.199 --> 00:02:21.080 Or, in some cases, it's the larva itself doing 00:02:21.080 --> 00:02:23.099 the boring so it can hide from predators while 00:02:23.099 --> 00:02:25.180 it feeds on the vascular tissue of the plant. 00:02:25.520 --> 00:02:28.539 The twig provides structural protection, insulation 00:02:28.539 --> 00:02:32.099 from the weather, and a built -in food source 00:02:32.099 --> 00:02:34.599 for the next generation. So it's less like a 00:02:34.599 --> 00:02:37.210 dine and dash and more like... I don't know, 00:02:37.250 --> 00:02:39.129 breaking into someone's house, eating all the 00:02:39.129 --> 00:02:41.110 food in their pantry, and then raising your kids 00:02:41.110 --> 00:02:43.770 in their living room walls. That is a highly 00:02:43.770 --> 00:02:47.650 accurate, if very disturbing way to picture it. 00:02:47.770 --> 00:02:50.490 I mean, it sounds awful. It is. And the tree 00:02:50.490 --> 00:02:52.250 doesn't just sit there and take it either. The 00:02:52.250 --> 00:02:54.370 source material specifically highlights the damage 00:02:54.370 --> 00:02:57.210 on the acer negindo, which that's the box elder 00:02:57.210 --> 00:02:59.090 tree. Right, the box elder. And it points out 00:02:59.090 --> 00:03:01.710 two key pieces of physical evidence left behind 00:03:01.710 --> 00:03:05.289 at the crime scene. Twig swelling and frass at 00:03:05.289 --> 00:03:07.780 the entrance hole. Okay, I need to stop you at 00:03:07.780 --> 00:03:10.060 frass because... A great word. It is one of those 00:03:10.060 --> 00:03:13.199 incredibly specific biology words that sounds 00:03:13.199 --> 00:03:16.060 polite, but is actually completely gross. It 00:03:16.060 --> 00:03:19.340 really is. Frass is basically insect poop mixed 00:03:19.340 --> 00:03:21.740 with wood shavings, right? I got it. It's the 00:03:21.740 --> 00:03:24.360 mechanical byproduct of the excavation. Grove. 00:03:24.419 --> 00:03:27.020 I mean, as the insect chews its way through the 00:03:27.020 --> 00:03:29.800 solid wood, it has to put that debris somewhere. 00:03:29.819 --> 00:03:32.259 Right. It can't just pile it up inside. Exactly. 00:03:32.360 --> 00:03:34.639 It can't just leave it in the tunnel or completely 00:03:34.639 --> 00:03:37.900 block itself in. So it pushes the digested and 00:03:37.900 --> 00:03:40.639 undigested sawdust back out the entrance hole. 00:03:41.360 --> 00:03:43.979 So you end up with this highly visible plugged 00:03:43.979 --> 00:03:46.879 up door wave debris right on the outside of the 00:03:46.879 --> 00:03:48.919 branch. And what about the swelling? Like, why 00:03:48.919 --> 00:03:51.199 does the branch swell up like a balloon? Is the 00:03:51.199 --> 00:03:53.319 mug injecting some kind of venom or something? 00:03:53.419 --> 00:03:55.639 No, no venom involved at all. The swelling is 00:03:55.639 --> 00:03:58.020 actually the tree's immune response. Wait, really? 00:03:58.030 --> 00:04:00.490 Maybe the tree does that to itself. Yeah. When 00:04:00.490 --> 00:04:02.949 the delicate inner plant tissue, which is called 00:04:02.949 --> 00:04:05.789 a cambium layer, when that is damaged by the 00:04:05.789 --> 00:04:08.849 boring, the tree attempts to compartmentalize 00:04:08.849 --> 00:04:12.530 the wound. It rapidly grows callus tissue, which 00:04:12.530 --> 00:04:16.490 is essentially plant scar tissue. Oh, wow. I 00:04:16.490 --> 00:04:18.290 didn't know plants got scar tissue. They do. 00:04:18.790 --> 00:04:21.009 It is desperately trying to wall off the invader 00:04:21.009 --> 00:04:24.329 and heal the structural breach. So this biological 00:04:24.329 --> 00:04:27.759 reaction creates a visible gall. or a swollen 00:04:27.759 --> 00:04:30.740 lump on the branch. That makes total sense. So 00:04:30.740 --> 00:04:32.480 if someone comes up to you and says, hey, I have 00:04:32.480 --> 00:04:35.420 a twig borer, it's basically like saying, I have 00:04:35.420 --> 00:04:38.300 a burglar. Yes, exactly. It tells you the exact 00:04:38.300 --> 00:04:41.500 crime like someone is chewing holes in your shrubs 00:04:41.500 --> 00:04:44.259 to build a nursery, triggering this massive swelling 00:04:44.259 --> 00:04:47.439 response, leaving gross frass behind. But it 00:04:47.439 --> 00:04:49.500 doesn't tell you who broke in. Not at all. You 00:04:49.500 --> 00:04:51.910 just know the strategy they used. Right. And 00:04:51.910 --> 00:04:54.069 the stakes for figuring out exactly who broke 00:04:54.069 --> 00:04:58.110 in are incredibly high. The text explicitly flags 00:04:58.110 --> 00:05:00.769 that many of these insects are major agricultural 00:05:00.769 --> 00:05:03.009 pests. Yeah, that stood out to me. These aren't 00:05:03.009 --> 00:05:04.850 just, you know, nuisance bugs hanging out in 00:05:04.850 --> 00:05:06.930 the deep forest somewhere. They are actively 00:05:06.930 --> 00:05:09.189 disrupting human agriculture on a global scale. 00:05:09.290 --> 00:05:11.769 Which means we need to look at the first major 00:05:11.769 --> 00:05:14.069 biological faction committing this crime, like 00:05:14.069 --> 00:05:16.750 the first syndicate. The beetles. The beetles. 00:05:16.850 --> 00:05:19.290 And I'm looking at this taxonomy list from the 00:05:19.290 --> 00:05:21.050 source right now. And I'm going to need you to 00:05:20.970 --> 00:05:23.009 to translate because I can't even pronounce half 00:05:23.009 --> 00:05:25.350 of these words. I can help with that. We've got 00:05:25.350 --> 00:05:30.850 the family, Bostrichidae. What am I even looking 00:05:30.850 --> 00:05:34.009 at here? Close. Bostrickidae. But don't worry 00:05:34.009 --> 00:05:36.110 too much about the Latin pronunciation. OK, good. 00:05:36.290 --> 00:05:38.949 Think of the Bostrickidae family as like the 00:05:38.949 --> 00:05:40.730 orchard syndicate. The orchard syndicate, got 00:05:40.730 --> 00:05:43.550 it. This group includes the apple twig borer, 00:05:43.790 --> 00:05:46.290 the branch and twig borer, and the great cane 00:05:46.290 --> 00:05:49.069 borer, which specifically targets vineyards. 00:05:49.310 --> 00:05:52.709 So they are going after very specific, high -value 00:05:52.709 --> 00:05:55.310 fruits. Apples, grapes. Yes. But then there's 00:05:55.310 --> 00:05:57.050 a totally different family listed right below 00:05:57.050 --> 00:06:00.990 it. The, uh, curculionidae. Right, the curculionidae. 00:06:01.170 --> 00:06:04.029 Those are the true weevils. Okay. This family 00:06:04.029 --> 00:06:07.149 is home to the black twig borer, which is actually 00:06:07.149 --> 00:06:09.449 more famously known by its other common name, 00:06:09.850 --> 00:06:12.689 the coffee twig borer. Okay, I'm genuinely confused 00:06:12.689 --> 00:06:15.980 now. Why is that? If a beetle boring into a grapevine 00:06:15.980 --> 00:06:18.939 and a beetle boring into a coffee plant are doing 00:06:18.939 --> 00:06:22.600 the exact same thing, like drilling a hole, leaving 00:06:22.600 --> 00:06:25.639 frass, making a nurse, why classify them differently? 00:06:26.000 --> 00:06:28.759 Aren't we just splitting hairs here? Like, why 00:06:28.759 --> 00:06:32.759 isn't there just one massive twig bore beetle 00:06:32.759 --> 00:06:34.620 family? I mean, it definitely looks like splitting 00:06:34.620 --> 00:06:36.660 hairs from the outside. Right. But then you look 00:06:36.660 --> 00:06:39.199 at their internal biology and their evolutionary 00:06:39.199 --> 00:06:42.000 history. OK. What's fascinating here is the concept 00:06:42.000 --> 00:06:45.470 of convergent evolution. Virgin evolution. Yes. 00:06:45.949 --> 00:06:50.089 These beetle families are not close cousins at 00:06:50.089 --> 00:06:52.970 all. They split off from each other millions 00:06:52.970 --> 00:06:55.569 of years ago on the evolutionary tree. Oh, wow. 00:06:55.689 --> 00:06:57.910 So their internal anatomy, their mating habits, 00:06:57.970 --> 00:07:00.170 their larval development, it's all completely 00:07:00.170 --> 00:07:02.589 different. So it's not that one granddaddy twig 00:07:02.589 --> 00:07:04.550 borer beetle figured this out and passed the 00:07:04.550 --> 00:07:06.670 skill down to all its kids. No, not at all. It's 00:07:06.670 --> 00:07:09.250 that completely unrelated bugs looked at a twig 00:07:09.250 --> 00:07:11.709 and independently thought, hey, free real estate. 00:07:11.970 --> 00:07:14.610 Precisely. They encountered the exact same environmental 00:07:14.610 --> 00:07:17.129 pressures. Like what? Like the need to hide from 00:07:17.129 --> 00:07:20.550 predators, survive harsh winters. their young 00:07:20.550 --> 00:07:23.850 and they just arrived at the exact same biological 00:07:23.850 --> 00:07:26.689 job description because it works so incredibly 00:07:26.689 --> 00:07:30.019 well. That's crazy. The Cerambicide family. The 00:07:30.019 --> 00:07:32.259 longhorn beetles is a great example of this. 00:07:32.600 --> 00:07:35.379 The source lists them targeting a huge variety 00:07:35.379 --> 00:07:38.399 of plants from dogwood to poplar trees. Wait, 00:07:38.399 --> 00:07:40.300 I'm looking at the list for that family and it 00:07:40.300 --> 00:07:43.399 includes the blue pear twig borer and the grape 00:07:43.399 --> 00:07:46.839 wood borer. Yep. So we have multiple completely 00:07:46.839 --> 00:07:49.879 unrelated families of beetles attacking the exact 00:07:49.879 --> 00:07:53.220 same crops. We do. They're hitting apples, pears, 00:07:53.459 --> 00:07:55.959 grapes and coffee. I mean, it feels like a coordinated 00:07:55.959 --> 00:07:58.279 strike on the best parts of the human diet. Like 00:07:58.279 --> 00:08:00.230 they're hitting our breakfast in our happy hour. 00:08:00.529 --> 00:08:02.769 It really does feel that way. But the taxonomy 00:08:02.769 --> 00:08:05.490 reveals highly specialized warfare. What do you 00:08:05.490 --> 00:08:08.410 mean by specialized? Well, they aren't generalists 00:08:08.410 --> 00:08:10.649 casually munching on whatever leaf or branch 00:08:10.649 --> 00:08:12.430 happens to be nearby. Oh, so they don't just 00:08:12.430 --> 00:08:15.470 land on a random tree. Right. A grape wood borer 00:08:15.470 --> 00:08:18.029 has adapted specifically to the chemical defenses, 00:08:18.689 --> 00:08:21.370 the nutrient profile and the wood density of 00:08:21.370 --> 00:08:25.009 a grapevine. While a coffee twig borer has spent 00:08:25.009 --> 00:08:28.240 millennia cracking the biological code of the 00:08:28.240 --> 00:08:31.600 coffee plant. They are masters of their specific 00:08:31.600 --> 00:08:34.460 niches. Okay, so the beetles have basically franchised 00:08:34.460 --> 00:08:37.700 this whole wood boring operation across all our 00:08:37.700 --> 00:08:39.659 orchards and vineyards. Essentially, yes. And 00:08:39.659 --> 00:08:42.059 with their hard shells and strong mandibles, 00:08:42.200 --> 00:08:44.360 I mean, chewing wood makes total sense for a 00:08:44.360 --> 00:08:46.539 beetle. It does if it's the profile. But here's 00:08:46.539 --> 00:08:49.740 where it gets really interesting, because the 00:08:49.740 --> 00:08:52.779 source reveals an entirely different order of 00:08:52.779 --> 00:08:55.870 insects doing the exact same damage. The moths. 00:08:56.110 --> 00:08:59.389 Ah, yes. Second syndicate. Yeah. And arguably 00:08:59.389 --> 00:09:01.509 the more surprising one. It completely shatters 00:09:01.509 --> 00:09:03.929 my mental image. Like, when I picture a moth, 00:09:04.029 --> 00:09:06.710 I picture this delicate, dusty creature just 00:09:06.710 --> 00:09:08.690 fluttering around a porch light at night. Right, 00:09:08.730 --> 00:09:11.409 right. How is a moth chewing through solid wood 00:09:11.409 --> 00:09:13.590 and causing that intense swelling and frass we 00:09:13.590 --> 00:09:16.169 talked about earlier? It just doesn't seem physically 00:09:16.169 --> 00:09:18.789 possible. Well, that is the cognitive dissonance 00:09:18.789 --> 00:09:21.929 caused by the common name. Oh, OK. Explain that. 00:09:22.029 --> 00:09:25.179 When you hear moth, your brain immediately jumps 00:09:25.179 --> 00:09:28.500 to the adult stage. The thing with wings? But 00:09:28.500 --> 00:09:32.000 the damage, the actual physical boring into the 00:09:32.000 --> 00:09:35.500 wood, is almost exclusively done during the larval 00:09:35.500 --> 00:09:38.259 stage. Wait. We are talking about caterpillars. 00:09:38.559 --> 00:09:41.639 Oh, okay, so it's not the dusty moth with wings 00:09:41.639 --> 00:09:43.600 dive bombing a tree branch and trying to chew 00:09:43.600 --> 00:09:46.279 on it. No, no, not at all. It's the caterpillar 00:09:46.279 --> 00:09:48.799 chewing its way inside to safely hide while it 00:09:48.799 --> 00:09:51.470 transforms. Exactly. The adult moth just lays 00:09:51.470 --> 00:09:53.750 an egg on the bark. Makes sense. Then the larva 00:09:53.750 --> 00:09:57.009 hatches and immediately uses its highly specialized 00:09:57.009 --> 00:09:59.889 mouth parts to chew its way inside the vascular 00:09:59.889 --> 00:10:02.509 tissue. Oh, wow. It spends its vulnerable developmental 00:10:02.509 --> 00:10:05.070 months hidden safely inside the wood, pushing 00:10:05.070 --> 00:10:07.970 out frass and pupating in complete safety. That 00:10:07.970 --> 00:10:11.409 is so smart. It is. But the moth taxonomy provided 00:10:11.409 --> 00:10:14.190 in the source is just as extensive and just as 00:10:14.190 --> 00:10:16.690 complex as the beetles. And just as hard to pronounce. 00:10:16.730 --> 00:10:18.389 Yeah. Let's break down these moth families because 00:10:18.389 --> 00:10:20.720 they seem incredibly organized. Let's do it. 00:10:20.879 --> 00:10:23.679 First we have the family jilikeidae. Yes. This 00:10:23.679 --> 00:10:26.980 includes the coyote brush twig boar moth and 00:10:26.980 --> 00:10:29.820 significantly the peach twig borer. So there 00:10:29.820 --> 00:10:32.519 goes another breakfast fruit. Yep, the peaches 00:10:32.519 --> 00:10:34.580 are compromised too. And then we move to the 00:10:34.580 --> 00:10:37.580 family crambidae. Okay. Which features the erythrina 00:10:37.580 --> 00:10:40.519 twig borer. Followed by the family tortricidae, 00:10:40.519 --> 00:10:42.980 which seems to cover a lot of ground. It includes 00:10:42.980 --> 00:10:45.679 the cottonwood twig borer, the indigo bush twig 00:10:45.679 --> 00:10:48.279 borer, and the locust twig borer. It's a very 00:10:48.279 --> 00:10:51.179 busy family. But the source carves out a very 00:10:51.179 --> 00:10:53.600 specific genus under this family that really 00:10:53.600 --> 00:10:57.159 caught my eye. The genus Proteoterus. Ah, yes. 00:10:57.399 --> 00:10:59.580 This is where the biological mapping becomes 00:10:59.580 --> 00:11:02.360 incredibly granular. It really does. Because 00:11:02.360 --> 00:11:05.179 this single genus, Proteoterus, seems to have 00:11:05.179 --> 00:11:07.360 an absolute obsession with the boxelder tree 00:11:07.360 --> 00:11:09.879 we mentioned earlier. They do love the Acer Nagundo. 00:11:09.980 --> 00:11:11.879 But they divide it up geographically in a way 00:11:11.879 --> 00:11:15.019 that just blows my mind. How so? You have Proteoterus 00:11:15.019 --> 00:11:17.500 Willingana, which is the eastern boxelder twig 00:11:17.500 --> 00:11:21.149 borer moth. then Protearis crescentana, the northern 00:11:21.149 --> 00:11:24.669 boxelder twig borer moth, and Proteodorus arizona, 00:11:24.950 --> 00:11:28.330 the western boxelder twig borer moth. Plus, just 00:11:28.330 --> 00:11:30.070 for good measure, they throw in the maple twig 00:11:30.070 --> 00:11:32.230 borer. Yeah, this raises a really important question 00:11:32.230 --> 00:11:34.590 about adaptation and territory. What you are 00:11:34.590 --> 00:11:37.309 looking at there is an ecological division of 00:11:37.309 --> 00:11:40.480 labor. It's like fast food franchises. Honestly, 00:11:40.620 --> 00:11:42.600 that's not a bad analogy. Like, the overarching 00:11:42.600 --> 00:11:44.799 corporation is the moth, but they've set up a 00:11:44.799 --> 00:11:47.919 specialized northern franchise, an eastern franchise, 00:11:48.100 --> 00:11:52.259 and a western franchise. But how does one genus 00:11:52.259 --> 00:11:54.980 end up dividing a single tree type across a whole 00:11:54.980 --> 00:11:57.360 continent like that? Well, it all comes down 00:11:57.360 --> 00:12:00.000 to the regional varieties of the host tree and 00:12:00.000 --> 00:12:03.220 the local climate. Okay. A box elder tree growing 00:12:03.220 --> 00:12:07.200 in the arid west. has different sap flows, different 00:12:07.200 --> 00:12:10.159 budding times, and different environmental stressors 00:12:10.159 --> 00:12:12.740 than a box elder growing in the humid east. Oh, 00:12:12.740 --> 00:12:15.120 sure. The tree behaves differently. Exactly. 00:12:15.480 --> 00:12:17.779 So the moths had to adapt their life cycles to 00:12:17.779 --> 00:12:20.299 sync perfectly with the tree's biology in that 00:12:20.299 --> 00:12:23.440 specific region. Oh. So the western moth caterpillar 00:12:23.440 --> 00:12:25.779 needs to hatch at the exact moment the western 00:12:25.779 --> 00:12:28.039 box elder is most vulnerable. Right. Which might 00:12:28.039 --> 00:12:29.580 be a totally different month than the eastern 00:12:29.580 --> 00:12:32.179 box elder. You hit the nail on the head. Nature 00:12:32.179 --> 00:12:34.940 produced entirely different species of moths 00:12:34.940 --> 00:12:37.860 just to tackle those regional nuances. That is 00:12:37.860 --> 00:12:40.559 wild. The eastern moth doesn't need to compete 00:12:40.559 --> 00:12:42.840 with the western moth because they have specialized 00:12:42.840 --> 00:12:45.139 their geographical reach. They just stay in their 00:12:45.139 --> 00:12:48.220 land. Pretty much. They are all attacking the 00:12:48.220 --> 00:12:50.960 same type of tree, utilizing the exact same boring 00:12:50.960 --> 00:12:54.240 behavior, but their timing and regional adaptations 00:12:54.240 --> 00:12:57.820 are so specialized that they require completely 00:12:57.820 --> 00:13:00.850 separate scientific classifications. Okay. So, 00:13:01.330 --> 00:13:03.269 what does this all actually mean for the person 00:13:03.269 --> 00:13:05.669 dealing with these bugs? We've explored the Beatles, 00:13:05.929 --> 00:13:08.169 we've explored the moth caterpillars, the northern 00:13:08.169 --> 00:13:11.070 franchises, the eastern franchises. We have this 00:13:11.070 --> 00:13:14.590 massive, confusing roster of suspects. And this 00:13:14.590 --> 00:13:16.669 brings us to the fundamental problem that this 00:13:16.669 --> 00:13:18.809 Wikipedia source is actually trying to solve. 00:13:18.990 --> 00:13:21.549 The danger of relying on human language to describe 00:13:21.549 --> 00:13:24.360 the natural world. Exactly. At the very bottom 00:13:24.360 --> 00:13:27.059 of the page, the text explicitly notes that this 00:13:27.059 --> 00:13:30.039 is an index of articles on animal species with 00:13:30.039 --> 00:13:32.740 the same common name. Right. A disambiguation 00:13:32.740 --> 00:13:35.720 page. It's basically acting as a biological traffic 00:13:35.720 --> 00:13:39.440 cop. It even warms the reader, saying, if an 00:13:39.440 --> 00:13:42.039 internal link led you here, you may wish to edit 00:13:42.039 --> 00:13:44.279 the linking article so that it links directly 00:13:44.279 --> 00:13:46.820 to the intended article. If we connect this to 00:13:46.820 --> 00:13:49.799 the bigger picture, This page illustrates why 00:13:49.799 --> 00:13:52.179 strict scientific classification isn't just, 00:13:52.179 --> 00:13:54.379 you know, academic snobbery. Right, it's not 00:13:54.379 --> 00:13:56.919 just scientists being pretentious. Exactly. It's 00:13:56.919 --> 00:14:00.519 a crucial disambiguation tool in a world of information 00:14:00.519 --> 00:14:03.919 overload. We often complain that scientific names 00:14:03.919 --> 00:14:05.860 are too hard to pronounce. Which I definitely 00:14:05.860 --> 00:14:08.919 did earlier. Which is fair. But they prevent 00:14:08.919 --> 00:14:12.080 a cascading series of errors. Let's put this 00:14:12.080 --> 00:14:14.419 into a practical scenario for you listening to 00:14:14.419 --> 00:14:17.519 really see why that matters. Say you are a farmer. 00:14:18.080 --> 00:14:20.620 You are trying to protect your peach trees or 00:14:20.620 --> 00:14:23.100 maybe your grapevines. You see the swelling on 00:14:23.100 --> 00:14:24.740 the branch. You see the frass pushing out of 00:14:24.740 --> 00:14:27.899 the entrance hole. You pull out your phone and 00:14:27.899 --> 00:14:31.279 you search for how to stop a twig borer. Because 00:14:31.279 --> 00:14:33.519 that's what everyone calls it. Right. And based 00:14:33.519 --> 00:14:36.139 on the source, you might end up reading an article 00:14:36.139 --> 00:14:39.720 about a moth, say, the peach twig borer. But 00:14:39.720 --> 00:14:42.559 what if your actual problem is a beetle? Right. 00:14:43.419 --> 00:14:47.500 Say the grape wood borer. The common name traps 00:14:47.500 --> 00:14:49.500 you into thinking they are the exact same pest. 00:14:49.899 --> 00:14:52.740 And why is that a trap? Like if they both bore 00:14:52.740 --> 00:14:55.120 into wood, can I just spray the same stuff or 00:14:55.120 --> 00:14:57.460 use the same traps? Does it really matter if 00:14:57.460 --> 00:14:59.639 it's a moth or a beetle if the end result is 00:14:59.639 --> 00:15:02.980 a dead branch? It matters immensely. Oh. Yes. 00:15:03.039 --> 00:15:05.659 The treatment for a beetle infestation is radically 00:15:05.659 --> 00:15:07.909 different from treating a moth caterpillar. Oh, 00:15:07.950 --> 00:15:09.970 I guess that makes sense. A farmer might use 00:15:09.970 --> 00:15:14.409 a specific biological control like a pheromone 00:15:14.409 --> 00:15:18.429 trap designed to confuse mating adult moths or 00:15:18.429 --> 00:15:20.710 maybe a targeted bacterium that only affects 00:15:20.710 --> 00:15:23.669 caterpillars. If you apply that to your orchard, 00:15:23.929 --> 00:15:25.850 it will completely bounce off a hard -shelled 00:15:25.850 --> 00:15:27.710 beetle. It won't do anything. Not to mention 00:15:27.710 --> 00:15:29.490 the timing. Like we talked about with the fast 00:15:29.490 --> 00:15:32.230 food franchises, a moth might be vulnerable as 00:15:32.230 --> 00:15:35.259 a caterpillar in early spring. But a beetle might 00:15:35.259 --> 00:15:37.580 be actively boring into the wood in midsummer. 00:15:37.840 --> 00:15:40.139 Exactly. The life cycles and vulnerabilities 00:15:40.139 --> 00:15:43.059 are entirely different. If you time your agricultural 00:15:43.059 --> 00:15:45.360 intervention for a moths mating season, but you 00:15:45.360 --> 00:15:47.799 actually have a beetle problem, you have wasted 00:15:47.799 --> 00:15:50.919 thousands of dollars, dumped chemicals for no 00:15:50.919 --> 00:15:53.379 reason, and your crop is still going to be destroyed. 00:15:53.500 --> 00:15:56.740 That is brutal. It is. The vernacular name, the 00:15:56.740 --> 00:15:59.519 common name, is convenient for casual conversation 00:15:59.519 --> 00:16:01.899 over the fence with your neighbor. Sure. But 00:16:01.899 --> 00:16:04.220 when it comes to biology and pest management, 00:16:04.659 --> 00:16:07.399 precision is literally the difference between 00:16:07.399 --> 00:16:10.019 saving a harvest and losing your livelihood. 00:16:10.519 --> 00:16:12.639 It is a phenomenal reminder that words matter, 00:16:12.840 --> 00:16:15.480 and sometimes a convenient label completely hides 00:16:15.480 --> 00:16:18.360 a complex, high -stakes reality. Nature doesn't 00:16:18.360 --> 00:16:21.179 care about our naming conventions. It only cares 00:16:21.179 --> 00:16:24.179 about what works. And boring into twigs clearly 00:16:24.179 --> 00:16:26.279 works for a vast array of completely different 00:16:26.279 --> 00:16:28.799 insects. Okay, let's do a quick recap of what 00:16:28.799 --> 00:16:30.879 we've uncovered in this deep dive. Let's do it. 00:16:30.909 --> 00:16:33.429 We started with what sounded like a single simple 00:16:33.429 --> 00:16:36.750 bug, but discovered that a twig borer is actually 00:16:36.750 --> 00:16:39.370 an entire index of completely different animals. 00:16:40.009 --> 00:16:41.870 We were talking about an incredible showcase 00:16:41.870 --> 00:16:45.659 of convergent evolution. Absolutely. multiple 00:16:45.659 --> 00:16:48.679 scientific families of both beetles and moths 00:16:48.679 --> 00:16:51.700 that all independently stumbled upon the same 00:16:51.700 --> 00:16:55.159 brilliant destructive survival strategy. Chewing 00:16:55.159 --> 00:16:57.759 holes into the branches of trees to build a hidden 00:16:57.759 --> 00:17:00.740 nursery. Right. And they leave behind undeniable 00:17:00.740 --> 00:17:03.080 physical evidence that defensive tree swelling 00:17:03.080 --> 00:17:05.339 in the frass packed at the entrance hole. The 00:17:05.339 --> 00:17:08.140 telltale signs. And they are absolute terrors 00:17:08.140 --> 00:17:11.019 for agricultural staples. They have specialized 00:17:11.019 --> 00:17:13.480 to attack everything from your morning coffee 00:17:13.480 --> 00:17:16.640 to peaches. grapes, apples, and pears. They've 00:17:16.640 --> 00:17:18.519 really cornered the market. They really have. 00:17:18.819 --> 00:17:21.680 They have even divided up the map with specific 00:17:21.680 --> 00:17:24.380 moths targeting eastern, northern, and western 00:17:24.380 --> 00:17:27.359 box elder trees based on local climates. And 00:17:27.359 --> 00:17:29.299 through it all, we see why we can't just rely 00:17:29.299 --> 00:17:32.299 on common names. The scientific taxonomy is the 00:17:32.299 --> 00:17:35.119 only reliable way to tell these criminal syndicates 00:17:35.119 --> 00:17:37.420 apart and actually protect the crops we rely 00:17:37.420 --> 00:17:40.450 on. So for you listening right now... The next 00:17:40.450 --> 00:17:43.089 time you are enjoying a hot cup of coffee, or 00:17:43.089 --> 00:17:45.589 you pour yourself a nice glass of wine, or even 00:17:45.589 --> 00:17:47.329 if you're just sitting under the shade of a maple 00:17:47.329 --> 00:17:49.970 tree in your backyard, take a second to appreciate 00:17:49.970 --> 00:17:53.410 it. That plant survived a gauntlet of highly 00:17:53.410 --> 00:17:56.569 specialized wood -chewing pests that have spent 00:17:56.569 --> 00:17:58.670 millions of years perfecting the art of the break 00:17:58.670 --> 00:18:00.950 -in. It certainly gives you a new respect for 00:18:00.950 --> 00:18:02.569 the resilience of agriculture, doesn't it? It 00:18:02.569 --> 00:18:05.470 really does. And it leaves us with something 00:18:05.470 --> 00:18:09.829 deeper to ponder, too. What's that? Well, if 00:18:09.829 --> 00:18:11.970 two completely different branches of the insect 00:18:11.970 --> 00:18:14.829 family, tree beetles on one side and moths on 00:18:14.829 --> 00:18:17.589 the other, both independently evolved to chew 00:18:17.589 --> 00:18:20.990 holes and twigs as a survival strategy, what 00:18:20.990 --> 00:18:23.470 other seemingly unrelated creatures out there 00:18:23.470 --> 00:18:26.170 might be secretly sharing the exact same biological 00:18:26.170 --> 00:18:28.789 job description, just waiting behind a confusing 00:18:28.789 --> 00:18:29.390 common name?
