Moscow region, 02 sept, 2-2,5mm.
Sept. as I red isn't good time for Empididae and I could not see triangles on eyes, but still it seems to me Empididae.
One more question about Empididae. In may-july there was Hilara sp. which hunted from my pond surface (ID by Paul Beuk). Than they wanished. In mid-aug it appeared new flies hunting from pond surface, about two times less size. It is another Hilara sp or whatever else?

You are correct, this fly is a
Platypalpus, which belongs to 'Empididae' in the broadest meaning. The empidids of old have since been split into two large families (Hybotidae & Empididae sensu strictu) and a few small ones.
Platypalpus is now in Hybotidae.
Hilara is very species-rich (hunders of species in European Russia alone) and many species, coming and going through the summer, dance over water. I think most species have only one generation per year in northern Europe, but some have a partial 2nd brood.

Of course Hybotidae instead of Empididae is much less shamefull than Ephydridae instead of Dolichopodidae:(.
Thank you, Kahis
