Found this little one (while at work a couple of weeks ago),hunting Collembola at 3am :|. It was lit by security lights, on a metal bar laying on the ground.
This should test the experts....was a very dark specimen. Tibia 2 might give a clue, as seen on the photo of it in flight.. Any ideas???
More in hope....Roger

Thanks Igor
That was unexpected..:)..from the quality of the photo's.
Give yourself a large pat on the back from me. Don't think I've had this one before, although it is on my Checklist for Shetland.
Regards Roger

The second row of images made the ID easy because with the mid legs well visible it is unmistakably that species.

Maybe easy for you guys. Normally I would have binned images like these, but as you say, the mid leg tibia were so odd that I thought I would give it a try.

Dear Roger,
I agree with Dr Grichanov that the male belongs to Campsicnemus scambus, a very common species near open water and mud in usually canopied sites. However, the identity of the females cannot be deduced from the pictures, as the colour of the face is decisive here. C. scambus often occurs together with C. curvipes, but the females of the former species have a face that is entirely yellowish grey, whereas the face in C. curvipes is greyish white (upper part = epistoma) and coppery brown (lower part = clypeus). It might be worthwhile to check that out to ... double your species list.
I am happy to help with any questions concerning Palaearctic and New World dolichopodidae.
Cheers,
Marc
