Incredible series! What happens to the skin that the caterpillar sheds? Does it shrivel up and fall off or something else? I've never seen something like this, and haven't thought about how they go through their various stages - it's fun to watch.
It just kept squirming untilthe skin split all the way to the end and dropped off.
Thanks all for the complements it was a bit more of an effort than the usual posting. If we see it when it emerges, I will get some more pictures.
