Eristalis tenax (Linnaeus, 1758)
Diptera : Syrphidae
Common name: drone fly

Eristalis tenax is a European hoverfly, also known as the drone fly (or "dronefly"). The larva of E. tenax is a rat-tailed maggot. It lives in drainage ditches, pools around manure piles, sewage, and similar places containing water badly polluted with organic matter. The larva likely feeds on the abundant bacteria living in these places.

When fully grown, the larva creeps out into drier habitats and seeks a suitable place to pupate. In doing so it sometimes enters buildings, especially barns and basements on farms. The pupa is 1012 mm long, grey-brown, oval, and retains the long tail; it looks like a tiny mouse.

The adult fly that emerges from the pupa is harmless. It looks somewhat like a drone honey bee, and likely gains some degree of protection from this resemblance to a stinging insect. The adults are called drone flies because of this resemblance. In its natural habitat, E. tenax is more of a curiosity than a problem. Like other hover flies, they are common visitors to flowers,and can be significant pollinators.
Like many other fly species, males can easily be distinguished from females because they have larger eyes that almost touch, while females have smaller eyes that are spaced further apart. That in picture is a female.
Their larvae occasionally are pests around livestock and cause accidental myiasis in humans. Myiasis occurs when fly larvae infest humans and other vertebrate animals and feed on the host's living tissue and is a common occurrence in certain other Dipteran species, such as bot flies (human bot fly, horse bot fly) and screwworms.
