Hi,
Today the flowers of
Geranium pyrenaicum were quite crowded. Beside
Oedemera beetles there were small flies that, according to wing venation, should be Muscidae. Can we get closer?
Many thanks, Sundew

small, grey ... Tachinid ;)
Siphona, I think

I had Tachinidae in mind, too, but I expected a bristlier habit in this case... Okay, I'll change the title, but
Siphona would be a dead end in any case, I'm afraid! (There are still lots of pics from all possible angles though, so if morphology could lead to a name, I might find the decisive bristle...)

Siphona for sure (long, angled proboscis on a small grey.brown fly) ... and maybe
geniculata, if it has marginals in T1+2 - but I'm not sure how that rule-of-thumb stacks up outside the UK. :) Probably best to just put "
Siphona sp." :D

It is a Siphona with central marginals on syntergite 1&2, however, it's not geniculata, given the clear contrast between yellow vertex and white face. And the epaulette are reddish, so best suggestion would be S. cristata.
