Joanna drew my attention to this post. It is an anthomyiid and probably a female in the liturata subsection of Anthomyia. There are quite a lot of species in the punctipennis section (in which the punctipennis subsection is also included), (15 in total, 12 of them described recently in 2001 by Graham Griffiths in Nearctic Flies. These new species were mainly characterized by the genitalia in the males, and most of the females were unrecognised. It will be a question of finding pairs in cop, and catching them!
An excellent photo by the way.
