Hello!

A fly from tonight at 0 ?C at our house (Ostwestfalen/Germany). Length about 10 mm. Phaonia sp. again? Thanks!

P.S.: I was wondering, that the Nematocera this night were not presented by Trichoceridae or Mycetophilidae, but mostly Limoniidae: http://insektenfo...ntid=29583

Kahis, can you suggest a species? Since this species occurs in winter, it is most likely present in the Finnish fauna.

The hairy eyes, the reddish tip of the scutellum and the dark legs with the slightly lighter femora should narrow it down to a handful of species.

Thanks, Kahis!

These flies are present here for a few weeks and often resting at night at the gutter of our winter garden.

I tried to read the key for females.

The best match seems to be Ph. zugmayeriae.

Interesting! Haven't even heard of that species, yet... ;)

Wing cross-veins seems strongly infuscated, fore tibia with post. setae, no strong pre ac, I think it is a female P. tuguriorum.
P. zugmayeriae usualy has 3 post dc, more yellow on thorax (humeri, scutellum, wing base), 1 pre ac etc.

Thanks, Stephane! P. tuguriorum I already had here at the house:
