Drone fly, Rat-tailed Maggot
Eristalis tenax, subfamily Eristalinae.
It has dark colour wings, yellow and black bands body and large eyes, the warning colours just good enough to mimic a wasp. But it has short antenna, one pair of wings and those tell it is a fly.
The Drone fly in appearance bears a close resemblance to a honeybee. The larva has a long thin tail, thus, called a Rat-tailed Maggot. The rat-tailed maggot usually breeds in drains, sewage pools, and other stagnant water. This Drone fly is believed an introduced species to Australia.
