There were two or three males of this species at Fishery Falls, near Cairns, in December 2008/January 2009. They were generally perched high up, overlooking their territories and chasing away intruders. All of my shots of these butterflies were taken using my longest lens, and even with a 300mm lens and 1.4x teleconverter the butterflies still look very small.
