I only saw these butterflies in a few places at Iron Range. The best spot seemed to be around the second Gordon Creek crossing, on the road out from Lockhart River. I also saw a few near the start of the Old Coen Road near the Rainforest campsite, and the occasional one or two showed up in other rainforest areas.
I was surprised to see that the males looked significantly larger than the females, as according to my books they're supposed to be the same size.
