General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
The hairy eyes, very large feet pads & orange collar steered us away from Fleshflies when trying to id this fly.
It's parent parisitised a Clear Winged Snout Moth (Genduara subnotata) that we caught, which then cocooned.

The caterpillar seemed quite lethargic when we found it. Then realised it was damaged in the top/middle. Thought it was bruised.In these situations we keep them to stop the ants attacking them; let the ants have them once they've died. When photographing it, it exhibited strange behaviour, rearing up bending at the "bruised" area. To our surprise it started cocooning that afternoon. A couple of days later a different pupal case appeared in the insect box. It looked a little like a cockroach ootheca. 5 weeks after the caterpillar cocooned this fly emerged.
