Underbark fly pupa - Chalcosyrphus libo

Underbark fly pupa - Chalcosyrphus libo
Nashua, Hillsborough County, New Hampshire, USA
March 18, 2006
Size: about 12 mm
This is one of the pupae I gathered from under loose, moist deciduous bark. It's not the pupa this fly came from, but another that looked very similar did come out of it less than an hour after I photographed it.
