As with the previous, apologies if I've already asked about this one. They do photograph very nicely sometimes though - and such beautiful flies.

Sorry, it is
Dolichopus ungulatus (Linnaeus, 1758):
bristles on hind and mid basitarsi and femora are present.

Igor,
a purplish spot above notopleuron is only present in
Poecilobothrus (see Brooks 2005).
D. ungulatus has the costal vein swollen and long ventral hairs on femur II and III.

Yes, Stefan, some details are not distinct. But I think a spot above notopleuron is not a true purplish spot; it is a shady place surrounded with large copper halo because of sunshine.
Poecilobothrus has rather specific curvation of M vein, and I do not remember species with dorsal seta on mid metatarsus. So, it is certainly
Dolichopus, I think.

Thanks Stefan and Igor. So can I say certainly
Dolichopus ungulatus, certainly
Dolichopus sp. or probably
Dolichopus sp.?
