Taken on the 18th in my garden. On coastal shingle, but there are plenty of freshwater habitats close by.

No, not Tetanocera. I think this is Coremacera marginata.

Thanks Jan. Could you (or anybody else for that matter) suggest a reasonably up to date key for this family?

I use:
Rozkosny, R. 1984. The Sciomyzidae (Diptera) of Fennoscandia and Denmark. Fauna Entomologica Scandinavica Vol. 14. E.J. Brill/Scandinavian Science Press Ltd.

Covers nearly all the British species Smile, and is on Amazon for not too huge a price.

Why not Euthycera?

Coremacera has hairy apex of antennae.
Really, Coremacera and Euthycera are very related genuses in all other characters...

Thanks for that Martin - I'll have to do some e-shopping I think! I must admit I have looked at similar species in the past and wondered whether they were Coremacera or Euthycera and couldn't work out the difference between the genera. Thanks for that little discussion Nikita and Rui!
