From my usual walk along the edge of woodland by a beck. 8mm long.
I think it is Sphegina rather than Neoascia but I've no idea which species.
I still have it if any information is needed from microscopy.
Thanks
Peter

Hi Peter,

Surely it is Sphegina clunipes. The position of the r-m cross-vein is the crucial point, being clearly beyond the end of the sub-costal cell. Beautifully clear picture!

Cheers, Tony
