Eristalis pertinax Scopoli 1763 ♂
Common names: Tapered Drone Fly [En], Eristale opiniâtre [Fr], Kegelbijvlieg [Nl], Gemeine Keilfleck-Schwebfliege [De]
Meise, BRABANT ● Belgium
Description: Often confused with the Drone Fly, E. tenax and E. similis, but on closer examination, E. pertinax has an entirely orange front tarsus (unlike both of the other species) and the hind tibia is pale in the basal half (unlike E. tenax). E. tenax has also a broader facial stripe between the eyes. E. interruptus has black front tarsi.
Biology : Visits a wide range of flowers, very often in company with the very honey bees it mimics. The males commonly hover in woodland clearings, aggressively defending territories as small as a few metres square. Flight period: March to November, with peaks in May and August.
Habitat: Various flowers.
