Moscow region, july, 3-4mm.
My work with identification key lead me to superfamily Opomyzoidae.
Am I right, please.

The top one is a member of the Lauxaniidae, but I am at the moment hesitant to put a name on it.
The bottom one, I think, is
Clusia flava of the Clusiidae.

1. Thank you Paul.
2. My message with two "long-snout" Syrphidae disappeared from forum sooner than I write in my notebook the name of second fly genus identified by Mr.Kahis

If I had to guess I would also have called the top one a lauxaniid. However I disagree on the second one. In the
Clusia flava specimens I have studied I remember seeing dark spots at the back of the head which are missing in you specimen. More important your specimen has post-ventral bristles, which should be absent in
Clusia flava. It does remind me of a member of the Scatophagidae, more specifically
Norellia spinipes! Maybe Herman de Jong can confirm this.

You got a point. However, as far as I know the
Norellia species are active much earlier in the year as the adults have to oviposit on daffodils. Maybe another scathophagid?
And Herman is still no member of this group...

How about
Norellisoma spinimana (also Scatophagidae)? In my notes I have collecting data of this species (all identified by Herman de Jong) from April, May, June, July, August, and September. This species also fits better considering the orbital bristles!
The larvae of
Norellisoma spinimana are stem-borers in various
Rumex species.
