Oh really... Cocoons are for moths? Chrysalids for butterflies?
I am amazed at what I learn on PBase.

There are some science teachchers out there who would love to have this iage to share with their kids. Interesting, thanks for the explanation.

I am so impressed, Pete. I didn't know about the darker ones, either. I have seen so few....and this year especially. Well done!

How very interesting. Now I know what to look for. They ate my maypop vine to pieces and we had giant caterpillers, but I have not seen anything since. Thank you, I shall look. V

Well this is a petesie proud photo if ever there was one. Thanks for the nature lesson... I did not know there was a way to judge the relative age of a chrysalis. This is wonderful. I am very jealous. As I tried to explain to Petesie, my caterpillar photos are always a disaster

Caterpillars are one of my weird fears! Imagine what this image is doing to me! I can barely type! ;o)
