General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
About 10mm long (excluding the ovipositor).
Had lots of them at the night light, along with many smaller beetles (assume scarab). You could well think that with the ovipositor it's a fruit fly. But no, a related family, Pyrgotidae, also called Light Flies as they come to night lights. Scarab flies because they parisitise scarab beetles. Very distinctive head shape, but couldn't get the wings veins very clearly. The body hair is diagnostic for this genus. Looking at Facilina sp, the hairs are tiny in comparison.
