The museum has plenty of the tropical pipevine so obtaining it would not be a problem. They're always down for some caterpillar experimentation. They've been feeding various pipevines to the Pipevine ST cats to see what they survive best on. I guess I also have to take into account that I did not find these guys as eggs, but as (probably) second instar caterpillars. So who knows what they were exposed to before I found them. Still, it's a bummer when you lose a caterpillar. But like the link I posted said, you can't blame yourself when nature is working toward caterpillar control. After all, if every egg made it to adulthood, they would have already eaten all the host plants, thereby making themselves extinct.
