... #4 was found in a dark forest in the Eifel mountains. Is it the common species as labeled? Thanks for any comment in advance. Frank

Hi Frank.
I guess this fly was 1,5-2 times smaller that your ScioV?
I think it is Trypetoptera punctulata.

As for your second question, Frank.
In Sciomyzidae key for Europe part of Russia, both Euthycera and Trypetoptera called "common".
My short (one year) experience in Diptera tell me so far "not at all as common or I don't know right places to search".
In fact during last summer I have seen Euthycera only once, and only once I have seen Trypetoptera collected by my friend and this site member Dima (Black). And this two imeges (Black's and mine) was the only images of Euthycera and Trypetoptera which ever appeared on this site from Europe (one more Euthycera from US was photographed by Stephen as far as I remember).

I'd call Trypetoptera widespread and quite common, at least in wet boreal forests. Unlike most other sciomyzids it is not exclusively a shore species, although it can be found on shores. It is perhaps seldom photographed because it lives on shaded habitats and it is seldom seen on flowers or upper leaves of plants.

E. chaerophylli is in my experience very local, but once you find it you'll see more than one specimen.

Thank you very much, Nikita. And thank you very much for your other Sciomycidae identifications too! This small fly seems to be common in forests here too. @Kahis: I suppose, I have captured this species with my beetle net many times.

Maybe the series of the right Euthycera will be completed by more photos. There are some more Sciomycidae and I would be glad to get some more names.
Best regards
Frank

The family name is correctly SciomyZidae, not Sciomycidae. It is quite important not to miss the names, because later visitors will not find your threads with the search option.
