Anybody know what kind of caterpillar this is? They're everywhere in central Virginia this week (mid-August, 2004). The body looks like a Pipevine Swallowtail Caterpillar, but the markings are a bit different. Ours has vertical stripes running the length of the body. We've had no luck keeping them in captivity; they're obviously interested in eating something other than the parsley we've been offering it. Any ideas? Thanks for any help anyone can offer!
