Saturniid moth?
Would be my guess. These moths include luna moths, polyphemus moths, and many other giants. ^_^

Thank you for your swift reply.

This is a Polyphemus moth- Antheraea polyphemus cocoon

Polyphemus Moth
Thank you for your reply, I have never seen such a large cocoon, what would be the best way to overwinter this so it will emerge in spring? I would like to see what it looks like in its mature state.

hope this helps
If you can keep it outside in a secure container (so mice and such don't get at it) or in a container in a garage or shed that would be most natural. You can also keep it in a small container and keep it in the fridge crisper compartment.

I've been looking for these...
I've been trying my best to find & collect (empty) Saturniid cocoons to give to my mother (who is interested in see if she can spin the silk). Unfortunately I haven't been having much luck though I know that they live in the area (there a lot of woodlands around campus that I've seen the larvae & cocoons in previously, not to mention the adults of at least three species here on campus). Any ideas on where I should be looking? :(
