Hi,
This is another one of the flies that I found on the seaweeds washed ashore by the Baltic. The legs are more bristly.

Dear Nikita, you are the
Fucellia expert. How many species are found at the Baltic shore? I thought the flies below belonged to that genus, but I am uncertain whether the pics in the upper row show the same species as the pics in the lower row (the upper fly has brown tibiae and the lower one has grey ones.) In any case, they differ from the fly of my original thread that has a brown frons and much more bristles on the legs.
So I suppose that the pics of this thread show two or three species, and there is another one here (
www.diptera.info/...ad_id=9600) that has not yet got an expert opinion. Its legs are rather smooth, the frons is brown. Is
Fucellia thus variable? And are leg and head colours useful to discriminate between species? Please teach me...
Sundew
PS. Other
Fucellia experts should not feel excluded, of course - every advice is gratefully accepted!

Dear Sundew, unfortunely I'm not expert.
Fucellia is rather easy ID Anthomyiidae on genus level, but species level isn't easy even with speciemen under microscop. So either Fucellia sp., or start to collect ;)

I agree with Nikita that the lower five pictues are
Fucellia sp., but the top 5 are all Scathophaginae. There are a few species that are regularly found on the sea shore (and look superficially like
Fucellia)
