Neoascia podagrica has darkened cross veins that form a right angle (see
https://www.flick...638744863/ and compare with a
Sphegina in
http://syrphidae..../file/3049). I think we can see three straight dark lines here, so I would prefer that species. Labeling the pics "
Neoascia cf.
podagrica" should not be too wrong!
