I'd been trying for years to find this species. I'd been to Cairns many times, and Brisbane several times, and always I thought I'd have a good chance of seeing this butterfly. In April 2011 I found it in 3 different places, 2 spots at Cairns and then the following day at Atherton. Mostly they were found on or next to Alphitonia trees, which is one of their foodplants.
At Townsville in December 2017 I found this species to be common, especially at the Palmetum.
