Cave-dwelling fly - Amoebaleria defessa

Cave-dwelling fly - Amoebaleria defessa
Tawney's Cave, Giles County, Virginia, USA
February 5, 2018
These flies were common throughout Tawney's Cave. I never observed them flying, always just scuttling around on the cave ceiling.

Moved tentatively. Thanks, Steve.
Moved from ID Request.

looks like a heleomyzid
hard to say from the photo but this one is "Usually collected in or near caves"
