May. 16, 2008 - Does Anyone Know What This Is??

The kids found this in the yard.  They say it was in the dirt from a clump of grass they pulled up.  Since I wasn't there, I don't know.  I thought perhaps it was a cocoon or chrysalis.  At first I thought it might be a wasp or a hornet and then I moved on to the other ideas.

If anyone has any ideas as to what it is, I'd love to know!  When gently squeezed the "tail" moved... (yes, it was creepy)
