A Package!

I found this wonderfully wrapped 'package' on my white baneberry/doll's eyes plant (Actaea pachypoda). 

I'm not sure who or what made this cocoon, but they've done a very neat and thorough job of wrapping it up, so much so that I can't peek inside to find out.

I kept my eyes peeled for the opening (or is that what the doll's eyes are for?). Here is the cocoon, with the dolls' eyes developing on the upper left of the photo.

I found a hole in it 3 days later, but still don't know who the occupant was ... I don't know if the cocooned critter ate its way out, or if a predator ate its way in! The leaf is now discolored:
