Hello
Found in my appartment in NE of France Florange 57190, the 2023/08/07.
Length body 5 mm, wing 4-5 mm.
with these characteristic veins, I think it is Dolichopus griseipennis a male ?

Hello
what difference with Dolichopus diadema, I had read that D. diadema had black metatarse, mine also has black metatarse ?
Thank you
Louis

In Grichanov's key, D. diadema has "Facial clypeus at apex convex, not adjacent to eyes and distinctly projecting below level of lower eye-margin" while D. griseipennis has "Facial clypeus at apex straight, adjacent to eyes and not projecting below level of lower eye-margin".
