Hi

I arrive at Rhamphomyia sulcatina when running this one through Collin (British flies, vol. VI). The genitalia seem to fit alright – especially in the caudal view. Lateral view is perhaps a bit more iffy...
Otherwise it appears to be a match with the abdomen shining black. Bodylength ~ 7 mm.
Are there any alternatives to consider or is Rh. sulcatina the only option?

The fly was caught on 27. iv 2009 at a small lake on the outskirts of a forest with lots of Betula and Salix some 10 km from Copenhagen.

Regards,
