Quick question: I found a caterpillar on the street. I don't know if it's still hungry or whether it's ready to pupate. I want to rear it until hit hatches. Should I just give it a container with some leaf mulch at the bottom and some leaves above that?

Any idea how they hiss? I get the impression the sound comes from the anus, thus making the hissing sounds farts, but I can't really tell.

Nice job!
