Newly hatched Polyphemus moth caterpillars. I raise these guys every year, but this group is heterozygous for melanism. If I can keep this line going, I should have some melanistic adults in 2020. Top pic is the melanistic form and one from the line I'm raising. Bottom is a typically colored polyphemus.
Not sure how you ended up with the black one, but It is beautiful. Your language is going to require a little work from me. You're too amazing to complain about!
Thats really cool. Beautiful creatures.
