Sawfly cocoon.
Reasonably sure this is an empty sawfly cocoon.

Parasitized?
I agree it's a sawfly cocoon, but as for what might have emerged: the ragged, irregular opening shown in these photos is not typical for an emerging sawfly, in my experience, so I suspect an ichneumonid or some other parasitoid is what actually emerged from this cocoon.

Wow!
Thanks for the info! There are lots of parasitic wasp species in my area as well.

Thanks Eric!
I wish I could've seen the fly emerge, what a nice series of pics that would be!

More images to come, hope you'll stay tuned :^)
