RECOGNITION
Recognition
"Its body is darkish brown with orange yellow patches on the sides and upper surface, and it is covered with short fine hairs. It looks remarkably like a honeybee (Apis mellifera). The different species of Eristalis are very difficult to distinguish, but Eristalis tenax is one of the commonest of these honeybee mimics."
Description
Its body is darkish brown with orange yellow patches on the sides and upper surface, and it is covered with short fine hairs. It looks remarkably like a honeybee (Apis mellifera). The different species of Eristalis are very difficult to distinguish, but Eristalis tenax is one of the commonest of these honeybee mimics.
Body Length
10-15 mm.

BIOLOGY
Habitat
The adults feed on nectar from flowers and are often seen hovering in front of flower blooms in gardens in both urban and rural areas. The larvae feed on rotting organic material in stagnant water in a variety of locations.
Active Period
Late March to early December; most common in September and October.
Development
The larva of the Drone-Fly feeds on decaying organic material in stagnant water in small ponds, ditches and drains. Such water usually contains little or no oxygen and the larva breathes through the long thin tube that extends from its rear end to the surface of the water and that gives it its common name of "rat-tailed maggot".
