I'm very impressed with your rearing and hope you'll take further observations on this extraordinary species...I'll email to you directly with more info

Moved from Lycus.

I was disappointed when first one, then another, and finally all three of these larvae died, or at least quit moving. I almost put them in alcohol, but decided to watch their little corpses decompose instead. Two days ago, without my eyeglasses, I peered at their bodies: one, two three, four! Now wait a minute!

I put on my glasses and poked at them with a camel-hair paintbrush. One appeared to be alive and another was splitting open with what I first thought was a fungal growth. The live one was definitely alive and the fungal growth turned out to be a pupa, whether alive or dead I can't tell since it wouldn't move like most pupae do. The third might actually be dead, but I'll wait and see. The fourth was the shed skin of the live larva, which, because it was tough and opaque, retained the shape and appearance it had while occupied.

The University of Arizona Cooperative Extension for Yavapai County offers an image of a lycid larva that looks very much like the upper larva in this photo.
