Hi,

I saw this fly this summer (22/08/2011) in Alps (Chamrousse 1650m, France)
I didn't catch it. Some told me it could be Empis tesselata, but august seams to be late for this specie, no? And it was smaller thant the one i usually see in april

Empis tessellata

Thank for your answer.

How do you exclude Polyblepharis subgenus? Is there no risk to be something else in the Alps?

This one is quite characteristic in appearance: large, darkish, covered with yellowish grey tomentum in various shades (depending on lighting) brownish yellow wings with distinct yellowish base and (as a rule) dark legs with reddish tibiae. I think the shape and curvature of the abdomen would also rule our many other species.

Thanks a lot for your help and the explications Paul :)
