Small Spotty-eyed Drone Fly
Eristalinus sepulchralis · Order: Diptera · Family: Syrphidae
The small spotty-eyed drone fly is about 6.5 to 8 mm long and looks wasp-like up close but resembles a bumble-bee from a distance. It lives near wetlands, river and pond edges and is also found where livestock graze, especially near polluted ditches and slurry pits. Adults visit many flowers for nectar, while the larvae develop in nutrient-rich, rotting vegetation in small water bodies; they fly from mid-April to September.
