Has yellow stripes on head but not very clear probably due to fading or still being soaked in alcohol?

Species interactions

Perhaps pendulus, as hind tibia appears quite pale, but I don't think it is a certain ID, bearing in mind the poor condition of the specimen. Yellow stripes on head are not a specific ID criterion.

ID best done dry

Dry the specimen out for a few minutes and stripes, etc, will re-appear. It is very difficult to ID hoverflies when wet (ground beetles, etc too) as many identification characters disappear (colour patterns, shimmer stripes, setae positions, etc). With pitfall or Malaise trap material I always dry out certain invert groups (briefly) before identification. Otherwise very dubious dets!
