June 24 2007, New Brunswick, Canada, length 6mm.
Looks like Seioptera vibrans
SEE HERE.
Note: fly collected June 2007 and kept frozen, thawed and photographed 27 Jan 2008.
Seems a good way to preserve flies for photographing when insufficient time to photograph in the summer. Eye colour changes and arista shrivels, but otherwise seems OK.

Thanks Paul and Valery, I'll go with Seioptera vibrans and will submit it to the Gallery. Presumably a European species that somehow reached NA.

Tony, there are 2 species of Seioptera and 2 species of Pseudoseioptera in Canada/N of the USA. S. vibrans is the most common and transholarctic. A key has been published by G.C.Steyskal (Ann. Ent. Soc. Am., 1956, 49: 30-32)

Thanks again. I have a few books but no access to journals.
