I was amazed to find 3 large Imperial moth caterpillars got fooled by my earth pupator trap. These pupae are kind of interesting, they have little spines on their surface. When you hold them in your hand, they almost feel like sandpaper. They’re kind of spiky. On some moths you can tell their sex by the size of their antenna and/or the 4th segment down from their wings. From what I’ve read, I think I have my photo marked properly. I got a 50:50 chance of being right…..or wrong :)
I trapped these imperial moths caterpillars in a trap I set under the tree they were on. Here’s a photo of a trap under a little walnut tree.
The traps worked surprisingly well. This one is just a plant pot that was sliced down a side, slipped around the walnut tree and about 1/3 filled with sawdust. It turns out that most of the caterpillars’ have legs that are designed to grip tree stems, but not plastic container walls. So they end up crawling down the tree, into the plastic container and since they can’t climb the container walls they give up and decide to pupate inside the container. I then pull the bucket and collect the pupae.
