Wow! This is a great record, Sandra. The only other known location for this species in the region is at a few of the dams up from the woolshed in Mulligans Flat.
Tying into your fabulous sighting, I've now had the chance to process and submit a sighting of this at Molonglo Gorge (around 5-6 km away from my guesses) in the week before this. More evidence of this species in that area.
