This bug was found on a oak leaf in Knob Noster MO in Aug. It had parasitic wasp eggs laid on its back. I think it may be a species of the tomato hornworm. The color is similar but it’s shaped different. It’s almost oval but, flat on the bottom. One end of it had a little bit of a caterpillar body that would come in and out. It was stuck to the leaf. when I got it off and looked at the under belly it had many legs. almost centipede like.
Signature: I’m just interested in the bug. Whatever is easier
Your caterpillar is most likely a Yellow Shouldered Slug Moth Caterpillar, Lithacodes fasciola, and we agree that the parasites are Braconids. We found a photo on BugGuide of a similar parasite/host relationship.
