Episode 187: The Praying Mantis and the Cockroach

We finish off Invertebrate August in style, with great suggestions from Rosy and Kim! Also, I was a guest on The Flopcast last week if you want to hear me talking about DragonCon and birding with my friend Kevin! Also, he actually has a few pictures of me if you want to know what I look like (I hate having my picture taken). Further Reading: Why Do Mantids Only Have One Ear?

I’m your host, Kate Shaw. It’s the last week of Invertebrate August, but what a wild ride it’s been. We’ll round out the month with a few more listener suggestions, so thanks to Kim and Rosy for some awesome topics! Before we get started, though, last week I was a guest on The Flopcast, a hilarious and family-friendly podcast about geeky stuff like old cartoons and TV shows and music from when you were a kid, unless you’re a kid now in which case music from before you were born. I talked with the host Kevin about DragonCon, so if you are interested in hearing me talk about something besides animals, I’ll put a link in the show notes so you can go listen! But now, on to the invertebrates! First, let’s learn about the mantis, also called the praying mantis, which is Rosy’s suggestion. If you play Animal Crossing you’ll be familiar with the orchid mantis, but there are lots of species. Lots. Like, almost 2,500 species. They live throughout much of the world but are most common in tropical areas. All mantises have elongated bodies, enlarged forelegs used for catching and holding prey, and a triangular head with big eyes. The mantis walks on its two rear pairs of legs but holds its big front legs up to use as weapons. Most species have wings and can fly, some don’t, but they are all predators. Most are ambush predators who wait for an insect or other small animal to come near, then grab it with their spiny front legs. Mantises have good vision since they primarily hunt by sight. They’re also most active during the day. The mantis will eat, in no particular order, insects, frogs and other amphibians, lizards, snakes, small turtles, mice, small birds, spiders, other mantises, and fish. That’s right, fish. In 2017 a team researching insects in India observed a mantis catching guppies in a rooftop garden pond. To reach the guppies, it walked across the water-lilies growing on the water. The scientists observed the mantis catch and eat nine guppies over the course of several nights, and surprisingly, it hunted them in the evening and night when mantises aren’t usually active. Mantises can and will catch and eat hummingbirds by climbing onto hummingbird feeders or into flowering bushes, and when a hummingbird comes to feed, chomp! So basically,
