Short Stuff: Roly Poly...Bugs?

Episode Summary

In the episode titled "Short Stuff: Roly Poly...Bugs," hosts Josh, Chuck, and Jerry delve into the fascinating world of pill bugs, also known as potato bugs, wood lice, or more affectionately in the American South, roly-polies. These creatures, despite often being mistaken for insects, are actually crustaceans, closely related to crabs, lobsters, and shrimp. Originating from the Mediterranean, roly-polies have spread globally, largely due to the international plant trade, and have adapted to live entirely on land, a unique trait among crustaceans. Roly-polies breathe through gills and have developed a remarkable evolutionary response to predators and the need to keep their gills moist by curling up into a tight ball, a behavior known as conglobation. They possess a high tolerance for ammonia, allowing them to excrete waste through their shells without the need to urinate. Additionally, these creatures practice self-caprophagy, eating their own feces to extract any remaining nutrients. Roly-polies can also absorb moisture through both their mouth and a tube-shaped structure at their rear, showcasing their adaptability. The episode highlights the beneficial role roly-polies play in gardens. They are detritivores, feeding on decomposing plant matter, dead animals, and feces, which makes them excellent for composting. Furthermore, roly-polies have the unique ability to ingest and crystallize heavy metals like zinc, lead, and copper in their guts, potentially aiding in the remediation of polluted areas. Despite their potential to slightly damage garden plants by seeking moisture, the hosts argue that the benefits roly-polies bring to soil health and composting efforts far outweigh any minor harm, making a strong case for their presence in gardens. In summary, "Short Stuff: Roly Poly...Bugs" sheds light on the misunderstood world of roly-polies, revealing their crucial ecological roles and fascinating biological traits. The hosts encourage listeners to appreciate these little crustaceans for their contributions to our gardens and the environment at large.

Hey, and welcome to the short stuff.I'm Josh and there's Chuck and Jerry's here too. And it's short stuff.Cute, cute little bug edition. SPEAKER_01: That's right.We're talking about pill bugs or potato bugs or wood lice.What?Or for our English friends, cheeky pigs, penny sows or cheesy bugs. SPEAKER_02: I have no idea what we're talking about, Chuck. SPEAKER_01: We're talking about here in the American South, at least, roly polies. SPEAKER_02: Oh, roly polies. SPEAKER_01: Is that what you call them? SPEAKER_02: Yeah, that's what I've always called them.It's funny.I was trying to look up a map of their range in the United States, and all I could find was dialect maps of what people called them around the United States.So I have no idea what their actual range is, but I can tell you in the South, everybody calls them roly polies. SPEAKER_01: Well, if they call them something, that probably means they have them, right?Yeah. SPEAKER_02: Yeah, for sure.I mean, we have them.I've seen them before with my own two eyes. SPEAKER_01: That kind of shows you the range if it's named. SPEAKER_02: Boy, Chuck, I think I'm getting dumber by the month. SPEAKER_01: Oh, but you never know.They might be like, hey, they don't exist in Washington state, but we still call them grungers. SPEAKER_02: Yeah, we like to say the word chiggy pigs. SPEAKER_01: But we're talking about the little round, well, not round, round if they're threatened.We'll get to that.But the little thing that you probably think is an insect that looks like a little prawn or an armadillo with legs.And in fact, the scientific name is armadillium, arma, no, armadillidium. Yeah.Bulgari. SPEAKER_02: Very nice. SPEAKER_01: Jeez. SPEAKER_02: That's why people shortened it to Chiggy Pigs. SPEAKER_01: Yeah.And that's a roly poly. SPEAKER_02: Yeah.And actually, strangely enough, even though, like I said, I've seen them with my own two eyes in Georgia, they are from the Mediterranean initially, but they spread all over the world.You can find them all over the place because they were basically carried over through the plant trade, the international plant trade. SPEAKER_01: That's right.You want some plants?They're going to come with some, well, they're going to come with insects, but I keep saying insect.They're not insects.Should we go ahead and spoil what these things are? SPEAKER_02: Yeah, totally.It's one of the facts of the short stuff. SPEAKER_01: You take it. SPEAKER_02: Oh, thank you.So they're not insects, Chuck.They're not mammals.They're not birds.They're crustaceans.Yeah, I mentioned shrimp.Cousins to crabs and lobsters and shrimp.Yeah. SPEAKER_01: That's right.And there are 12 species in the United States alone.It says northern and central parts of the country, but maybe they don't dwell in like the deep deserts.Who knows?But I know I see them all over the place here.They're the only crustacean that has adapted to live entirely on land.And they breathe through gills, which is remarkable.Right. SPEAKER_02: Yeah, so the fact that they have adapted to live on land, the only crustaceans that did, that's another fact of the podcast.Just amazing stuff, right?But technically, it's a sub-fact of the fact that they're crustaceans, I guess.Another fact of the podcast, though, is there's a word for them turning into roly-polies, a tight little ball, which, well, I guess... marine biologists have determined was an evolutionary response to predators or to keep their gills moist.They curl up in a little ball, hence the name roly-poly.But there's a term for that.And I think you should tell everybody what that is. SPEAKER_01: All right.It is conglobation.Yeah. SPEAKER_02: Now, had I said it, I would have said conglobulation, but that's not correct.It's the better way to say it, but it's just not right.Yeah, you love adding things.Conglobation. SPEAKER_01: Fancying up a word.That's the Josh Clark way.For sure. So there's a lot of remarkable things here.We're going to tick off a couple of them and then take a break.But one of them is they do not urinate.They have a very high tolerance for ammonia.So they don't urinate.They excrete waste through the shells.They eat all kinds of things in the garden. But one thing that they eat... is their own poo-poo, which is a practice called self-carpropagy.Caprophagy.Self-caprophagy.Caprophagy.Yeah, I threw an R in there, didn't I?Yeah.They're poop eaters. SPEAKER_02: Yeah, they eat their own poop.And it's like, yeah, that's gross, but it also makes sense because you don't necessarily get all the nutrients out of your poop.So if you eat your poop, you have another shot at extracting more of the nutrients that were left over. SPEAKER_01: Yeah, like you missed something.Try again. SPEAKER_02: Yeah, there's a piece of shrimp in there, ironically. SPEAKER_01: They can drink from their mouth or they can drink from their hind end.They have a little tube-shaped structure in the back.And so it doesn't matter if the party's in the front or in the rear, they can still get their drink on. SPEAKER_02: That's funny.The joke I came up with is that they could use them both at the same time and share a milkshake with themselves. SPEAKER_01: Oh, that's even better.I think they're equally good.Well, I just thought of mine.It's not as good. SPEAKER_02: Well, mine's written down, so technically yours is better because it's off the cuff. SPEAKER_01: Well, you just made yours up, too.You just wrote it down. SPEAKER_02: True that. SPEAKER_01: Unless, did you workshop it over a couple of days? SPEAKER_02: Yeah.You'd be so tired of hearing that joke. SPEAKER_01: You're like, which one, Yumi?Shut up!Should I say milkshake or shake?How about one more factoid, and then we'll take a break. SPEAKER_02: Okay, yeah.They're crustaceans, but they also have a marsupial pouch, essentially. SPEAKER_01: Yeah, those mamas carry their little eggs around for two to three months in their marsupium.They hatch, and then sometimes even those little young'uns will go back in that pouch and say, Mama, I still want to stick around for a little while until I'm ready.Hey, Mama.Like Elvis. SPEAKER_02: Okay, now it's time for a break because the facts are coming so fast and hard that I'm crying tears out of my eyes right now of joy.All right, we'll be right back. Bye.

SPEAKER_01: Maybe you've stayed in an Airbnb before and thought to yourself, this actually seems pretty doable.Maybe my place could be an Airbnb.It could be as simple as starting with a spare room or your whole place when you're away.You could be sitting on an Airbnb and not even know it.Maybe there's a big tournament in town and lots of fans will be visiting.

All right.We're back with some more amazing facts. These little guys are arthropods, so they're going to molt.And if you ever see a little cheesy bog, what do they call them in England?Cheesy wig?Cheeky pigs?Cheeky pig?Or cheesy bugs. SPEAKER_02: Yeah, you're close. SPEAKER_01: Cheesy bug? Uh, and if you find one that's like, Hey, that thing looks funny.It looks like it's got half a shell.It's because their shells are in two pieces.There's a front and a back.They drop that back one first.So you may see one missing its back and you just gotta be, just leave that little, little fellow alone. SPEAKER_02: Yeah.He's porky pigging it.Yeah, that's exactly.Um, there's some other things you should know about them.Another reason to leave them alone and even to invite them into your garden, as you'll see, um, they don't sting.They don't bite.Um, They don't carry diseases.And not only do they not mess up your plants, they actually help your garden grow even better because these guys are soil maniacs. SPEAKER_01: Yeah.They are champions of your composting efforts because they get in there.They have what's called a detritivorous diet.Is that how you would say it? SPEAKER_02: Well, I would say detritivorous diet.Yeah. SPEAKER_01: That it means that they basically take anything that's from a decomposing plant or if there's a dead animal or other poop, they can absorb all those nutrients, poop it out themselves.And they're just little composting machines, which is pretty amazing.But to me, one of the most amazing facts is that they are into heavy metal. SPEAKER_02: Yeah.Like big time. SPEAKER_01: Crocus. SPEAKER_02: Sabbath. SPEAKER_01: Dio. SPEAKER_02: Dokken. SPEAKER_01: Maiden. SPEAKER_02: White Lion. SPEAKER_01: Oh, boo.God, what if we just name metal bands for the next six minutes? SPEAKER_02: Quiet Riot.Oh, man.Bang Your Head. SPEAKER_01: That's hair metal. SPEAKER_02: It's still metal.All right.It's the most metal of hair metal, I would say, Quiet Riot is.At least some of their songs. SPEAKER_01: Yeah, I like Quiet Riot.Yeah, they're great.That's good stuff. SPEAKER_02: What about Testament, the other Christian metal band? I don't think I knew about them. SPEAKER_01: Yeah, there's Testament.That sounds familiar, though. SPEAKER_02: I'm pretty sure they were Christian.They talked a lot about Christianity. SPEAKER_01: Did they rock hard for Jesus? SPEAKER_02: Oh, dude, they rocked super hard.They were like the kind where you could be like, I'm not at all religious, but I still like Testament. SPEAKER_01: Yeah, kind of like my boys in Striper. SPEAKER_02: Queensryche?They were weird, but they were still metal. SPEAKER_01: All right, so they love heavy metal.They love all those bands, except for White Lion.But what we really mean is they have a very unique ability to eat zinc and lead and copper and any other kind of awful heavy metal that might be out in the wild and crystallize it in their bodies and thrive in these heavily polluted, awful areas.They crystallize it in their guts and can remediate it, essentially.Wow. SPEAKER_02: Yeah, if you crystallize something, you're essentially encasing it in glass and it becomes inert as far as I can tell.So I don't know if they poop it out afterward and it's inert because it's been encased.But whatever they're doing there, they're remediating essentially superfund sites of heavy metals.If you just got a handful of them and said, I'll see you in 50 years. SPEAKER_01: Yeah, absolutely.So, like you mentioned, they're great for your garden.They may, I mean, the damage that they might be doing is pretty minimal.They might try and drink and get moisture from your plants and things, but they're not the kind of land crustacean that's just going to eat through all of your garden vegetables. SPEAKER_02: Right.They're no land crabs. SPEAKER_01: No, not a land crab at all. SPEAKER_02: You got anything else about roly-polies? SPEAKER_01: No, this is short and sweet. SPEAKER_02: Well, I'm glad that we did a pretty good PSA to let everybody know, leave the roly polies alone.And short stuff is out.
