Platystomatidae? Or something similar like Otitidae? I had thought too of Pyrgotidae, but apparently this family is not found in the western United States.

Location: Chihuahuan desert, on dry mammal scat containing many seeds. New Mexico USA.

Behavior: Several flies were present and they were waving their wings.

Date: 3 October 2007.

ID help appreciated!

Here is a second view with the wings closed, but most of the time the wings were held open.

i mean: i would go more for Ulidiidae - there are no preapical bristle on tibiae. ;)

Stephen, Otididae is no more a valid name for family. Now it is Ulidiidae. ;)

Ulidiidae: Acrosticta sp., pretty sure I just uploaded a similar fly to Bugguide, identified by E. Kameneva.

Acrosticta cf. rubida (Loew). Again, ID by Elena Kameneva. Some characters, however, seem disagreeing with the type of the latter species.
