Hi,
Can anybody help with determination of this fly?
I take the photo on 5 May 2013 Kokkola, Finland.
Regards Pentti.

Indeed Egle, probable one of the larger one's.
Egle ciliata, Egle brevicornis, Egle brevicornis ...and difficult to say from photos wich one it could be.
So I give you a short key from
Verner Michelsen:
3 Notopleuron around posterior seta with more than 3 accessory setulae. Hind tibia with apical pd-seta ..................... 4
4 Head about as long as high; parafacial widened downwards; haustellum and palp as long as largest diameter of eye(Fig. 28). Apical extension of cerci emarginate at tip (Fig. 59) .........................................
4. E. ciliata-
Head distinctly higher than long; parafacial widened upwards or parallel-sided; haustellum and palp shorter than largest diameter of eye (Figs. 29, 30). Apical extension of cerci pointed at tip (Figs. 65,71)..................... 5
5 Fronto-parafacial angle modest, lying well behind lower facial margin; parafacial parallel-sided, moderately broad;genal setae less abundant, standing in a narrow cluster (Fig. 29). Altogether less “hairy” species: proepisternals 1–2,proepimerals less than 10............................................................................5.
E. brevicornis-
Fronto-parafacial angle very prominent, reaching level of lower facial margin; parafacial strongly widened on upper part; genal setae very abundant, standing in a wide cluster (Fig. 30). Altogether more “hairy”: proepisternals 3–5, proepimerals more than15.................................................
6. E. anderssoni

Haustellum and palp very long and lower facial margin strong projecting....most change indeed it will be
E. ciliata(Walker), the most common one.
Next time you will pull out the genitals ? (I keep trying to confince you to prepare the genitals :P)
