Sciomyzidae, Limnia unguicornis?

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 CerambyX attached the following image: [72.99Kb] Edited by CerambyX on 29-12-2007 23:35

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... 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 Edited by CerambyX on 29-12-2007 23:34

SEE HERE - http://diptera.in...ad_id=8803 FOR anepisternum - NUMBER 21 anepimeron - NUMBER 4 FOR Microtrichia and setulae (small setae) you can find an explanation here in the 7th post --> http://diptera.in...ad_id=8790 mesonotum vitta (plural: vittae) Edited by jorgemotalmeida on 30-12-2007 00:14
