I grew rather fond of this species when I was first in Cairns. Every now and then one of these butterflies would appear out of nowhere and fly past me. Often they would land close to me even if I had inadvertently disturbed them - I wish more butterflies did that. When they feel threatened they can really disappear at a rate of knots, but most of the time they seem happy to just zoom away a short distance and then come back to the same area.
I did see this species on my return to Cairns in April 2006, but only the occasional specimen.
