QUESTION: It is a little bigger than dime but oval in shape.  Looks like it is in some type of insulation or nesting. Here are some additional photos. Thanks again.

Answer
They do look like some sort of cocoon, possibly a large fly or small moth. I can't see enough detail on the pupal case however to id much further. If you keep these in a covered container something may emerge eventually then you'll know for sure! Sorry I can't be more specific.
