Found crawling out of mud under a log. Looked too small for an annual cicada to me, so I'm thinking it's periodical. Couldn't remember if they were identifiable at this stage or what to look for, so I tried to take a bunch of photos.

Polyphemus Moth is a tentative identification. Cocoon was found attached to a Maple leaf under a Maple tree. Cocoon was badly dented and guessing that it was not viable, I cut it open. The inner cocoon is apparently intact - no holes, dents or cuts, and it seems solid and appropriately heavy. I have it in an outdoor rearing cage and if it ecloses I will post it with a link to this post. The other object is a completely dessicated grub/larva/caterpillar that was inside the outer cocoon and right next to the inner cocoon. I'd love to know what it is and how it got there. There were no visible holes in the outer cocoon.
