These first instar caterpillars are so cute, just a little white thing with a big, black horn at the rear end. What the heck does that thing do? Speculation: When I disturbed the caterpillar at one point, it arched its body so the horn pointed up. Maybe it defends against predators or parasitoids.

I have a couple of viable caterpillars from freshly-laid eggs, and I'll see if I can rear them.
