EXTRA - Photo Specific Information:
Most insects have 2 pairs of wings, but flies only have one pair. The Halteres are what's left over from the hind pair of wings. They are still used to help balance the fly in flight.
You can just see them here, the 2 white "balls" on the end of curved "sticks" on the side of the body, in front of the middle legs.

Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
