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

Thanks

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.?
