 Hello,

I photographed this fly in the Pyrenees, France. He looks like a Cylindromyia, but has no strong erect setae on the abdomen, and the vein m is very straight after its curvature.
Is it genus Cylindromyia or another ?

 Yes, a female C. pusilla.

 Ok, thank you very much !

Is she the only one not to have long erect bristles on the abdomen? Is that enough to recognize her?
