Hi,

this was collecetd by my friend and at first I was thinking abouth Egle but after closer look; not any more. Is this Anthomyiidae at all ? April 7 2010 Vantaa, Finland.

What about...Lonchaeidae :)

Oh yes, that's what it is. So I will put it to the endless line of undetermined Lonchaeidae :| Thank's Joke, You were faster than ever :)

Do you have: Hackman, W. 1956. The Lonchaeidae (Dipt.) of Eastern Fennoscandia. — Notulae Entomologicae 36: 89–115
and
MacGowan, Iain, and Graham Rotheray 2008; British Lonchaeidae. Diptera, Cyclorrhapha, Acalyptratae., Handbooks for the Identification of British Insects, Volume 10(15).
?

I haven't ID'd too many Lonchaeids, but when I have, I have been using these and it's been great fun and quite easy.

I have the British book but too many Finnish species are missing. Nice book anyway. Hackman I don't have but must try to find it somewhere. Thank's for the hint Viktor :)

Its a Lonchaeid and a male, my first thoughts so early in the season are that it may be Earomyia lonchaeiodes the lunule looks bare but the genae dont look as wide as I might expect - that species is keyed out in Hackman - if its not that just send it to me and I will be happy to have a look? ...... best wishes .......

Generally the most common lonchaeid here in spring, as Iain wrote above, is definitely E. lonchaeioides, the only species in its genus with entirely dark legs.

But perhaps you should check the genus against Protearomyia nigra, which I think Kahis has caught already in April too. Protearomyia should have "margin of scutellum with only four bristles, no intermediate hairs", while Earomyia should have "hairs between the 4 strong scutellar bristles".

And as there are hairs between scutellar bristles I believe we hava a name :) Thank You so much ! Kahis has the Hackman papers, so in future I can study the fly with the key and be sure.
