General Species Information:
Found in the Adelaide Hills and possibly elsewhere
Male ~40mm long, while the female was a little shorter at ~35mm.
The male is easy to identify based on size & wing shape. The female doesn't have the bulbous mid wing of the male, but we assume it's the same species based on other features & the fact this male is the only robberfly that comes to this size in the area.
Usually the mouth part/proboscis looks thick and we couldn't understand how it pierced it's prey. But here you can see it's somewhat telescopic. It retracts the sharpest point most of the time, but it's extended here.
We've found 4 males in Nov, Jan & Feb. One female in Jan.
