Hello everybodies,

I need your help to identify this small fly found among the dunes of the south coast of French Brittany next to a pond with reed.

Approximately 2mm, seen on September 05, 2018 in Palud Gourinet, 29710 Pouldreuzic (France)

The base of the wing is white and the crossveins are black. I did not find anything in Ephydridae... may be a Canacidae ?

thank you in advance.

Pierre-Yves

Thanck you very much Tony, I was totaly lost. After some research, I found Trixoscelis marginella (I had collected a specimen).

References :

thank you again,

Pierre-Yves

This female specimen is rather similar to T. obscurella by the lacking of dark long marginal stripe along the costal and subcostal wing veins section.

Where are the meaning abbreviations of Lindner's series Die Fliegen der Palaearktischen Region, ie. f1: anterior femur, ...and what about "p"? (I don't possess volume I)

17.07.19 19:37
Yup, you can view the wing from above (dorsal side) and from beneath (ventral side).

Hey Dipterists! Quick Question: Vein r2+3 bare beneath. I've always assumed that this is below as in when you look at the wing flat. Am I right? Thank youuuuu! Pfft
