A teacher at my daughters school brought this in as a big green caterpillar that she saw crossing the sidewalk. Next day went to school and it was in this cocoon. I should have put something there for size, it is about 2" long and about 1" in diameter.

Any ideas of where I should start looking to be able to ID.

I did not get a chance to see it as the caterpillar. They just said big and neon green. They dont remember seeing a horn. It pupated on the side of a glass jar and attached the other side to a papertowel that they had on top. I pulled off all the paper towel to get the picture.

So far I am thinking it might be a silkworm cocoon, anyone have any knowledge of these to know for sure?
