Thread subject: Diptera.info :: Calyptrate Fly At Maple Sap

As far as I can see, the arista of this fly is bare (maybe some tiny, tiny hairs, but it is not plumose). It was not especially large, measuring only 6.4 mm from the front of the eyes to the rear of the wings.

Based mostly on the bare arista, I am guessing Tachinidae? Not very confident, though!

With that plump abdomen and small, separated eyes, a female?

ID help will be appreciated.

West Virginia USA, woodlands at maple sap, 6 November 2006.

Vein M is straight, and anal vein appears to reach wing margin, so I'd say Anthomyiidae
