I'd forgotten about this gift from my good neighbor. I set it aside - planning to shoot it later and now it's much later. I think he gave it to me back in January. From what I could find out with a little research, this is a type of moth cocoon. As to a specific moth - maybe someone here will know. It almost feels a little spongey like latex and it seems to be woven in places with silky threads.
@rhoing I've narrowed it down to about three moths, but can't get it down any further than that. One was the Polyphemus Moth. Can't remember what the others were.
@rhoing The cocoon in the first link looks rougher compared to the one I shot which is smoother. I thought it might be the giant silk moth too, but I'm inclined to think it's this one.
A very interesting find. It kind of reminds me of a wasp spider cocoon. The female creates it in the autumn and then this cocoon is soft. Over time it dries, shrinks and becomes very hard.

You're definitely in the range of that moth; see the map:

@haskar Thank you very much, Haskar. This one is still pretty spongey feeling like a rubber glove.
