Submitted by: David Thompson
Taxon: Megastrophia concavus
Submit date: 2014-10-02
Location (approximate): Milan, Washtenaw, MI

Submitter notes: These inarticulates, the largest being Petrocrania hamiltonae, and 1.5 cm, are out of the way at the back of the big Megastrophia. The tiny ones are .76 mm and are in the Philhedra family but they may be stewerti or crenistriata sp., it is hard to tell.
