Hi,
Was checking my Sciomyzidae gallery and comparing with gallery on this site, and got little bit confused, because for me this one looks like Limnia unguicornis, but at the same time Euthycera species (fumigata, for example) look very similar. So is this Limnia or Eythycera, and what is the key difference on what I should look to identify these two genus?

Picture taken in Latvia, 11th of July, 2006, in the grass near small lake. Size as far as I remember ~7mm.

Thanks!

Ugis Piterans,
Latvia

Ugis, this is certainly a female of Limnia unguicornis Scopoli, besides the presence of setulae on anepisternum and anepimeron, it has a peculiar wing pattern, rather pale compared to Euthycera, and a pair of gray microtrichichose vittae on mesonotum, which is the characyter of L. unguicornis.

Thank you Nosferatumyia, for your quick and very informative answer.
Don't have any Diptera identification keys available at the moment, so I can only try to compare photographs of different species, but it's quite a headache if you don't know where to look... Grin I had also idea about that darker wing patter for Euthycera, but definitely it isn't very precise method to judge only by coloring.
So thanks for giving some idea how to identify them. Thanks!
And a Happy New Year to everybody Wink

FOR Microtrichia and setulae (small setae) you can find an explanation here in the 7th post -->
