Other than in Wilpattu I have seen this beautiful species at Arippu, Mannar, Murunkan, Giant’s Tank, Haputale, Sigiriya and Bandarawela.
This butterfly will often settle on foot-paths and other open areas during late morning to early evening with their wings spread open. When you get close enough to get a photograph it would instantly fly a little further and drop down to the ground again enticing you to follow as if it’s a game. I remember photographing one close to giants tank in the mid day heat where I had to kneel down, get up and walk a few yards on twelve occasion before the teasing Blue pansy permitted me to get some worth while photographs. One has to practice great patience and perseverance in photographing this butterfly.
The female of this species is known to lay their eggs on two species of wild flowers referred to in Sinhala as Dutu Sathutu Centranthera indica and Tiny Slitwort Lindernia pusilla both of which are commonly found in Wilpattu.
Other than at Eluwankulam I have seen this butterfly in Wilpattu at Periya Villu and Kollan Kanattha.
