This polyphemus moth gave us a surprise. We had the plump, green caterpillar for quite a while in our butterfly house waiting for it to come out of its cocoon and it never did so we took it out and left it on the counter. This week it hatched and we found the giant moth sitting on our stack of mail. It made for a great macro photography and fine art subject. The moth is about the width of a full size pencil with its wings open. It is an impressive and beautiful insect. Even our curious cat was interested in it.
