I first photographed this butterfly in a park across the road from the Cairns Botanic Gardens in October 2005. I admit I can't be 100% sure of the identification; I think it's T. augias, but as with so many skippers and darters it's hard to be certain.
I took more photos of it in April 2006, though I'm not 100% certain of the identification here either....
