Helophilus hybridus (f)
A female woolly-tailed marsh fly (iNat) or marsh tiger hoverfly (Falk) on knapweed in Chester Zoo Nature Reserve. One of three Helophilus species seen in the reserve that day.
Females are tricky to distinguish from the more common sun fly. This shot shows the two distinguishing features - a hind tibia that is mostly dark and a dusting that extends right the way up the frons.
