The butterfly is locally not rare in montane forest at low to moderate elevations (Alt. 300 - 800m). Males form flight paths along streams or forest edges, and frequently come to the banks of streams and puddles to suck water. They often rest on the underside of leaves.
Ek-Amnuay,[2007],2012 recorded it from Trang, but I have not seen any specimens except from Yala. Therefore, these records are not to be adopted until a reliable specimen is confirmed. Further distributional research is needed.
