Clusiodes ID?

Submitted by ewanparry on

Hi, 

Complete beginner here but I was hoping to get an ID for these flies I found on an old tree stump in a marshy area in York. The best I can do is that they are Clusiodes but beyond that I am a bit stuck. It may be that without specimens that's the best I can do. Following Mike's insect keys I get Clusiodes albimanus due to the three orbital bristles but I'm not entirely convinced. Any ideas welcome!

Very nice photos! I'd agree with Clusiodes, and I suspect that you are probably correct with albimanus (which is the one I see most often), but as far as I'm aware these are best confirmed by dissection of the males, and I'm not sure how reliable the orbital bristle character is.
