General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
Small light brown & white fly regularly seen floating on water. They float there lapping up water with their elongated mouths at a very rapid rate; so getting 2 drinking at once was pure luck. Took so many photo's to get one with the mouth actually touching the water and in reasonable focus. They are so light they can float on 4 legs while using the front, or rear, pair to clean themselves.
