The butterfly is locally common in montane forests at low to moderate elevations (Alt.10 - 1600m). Males frequently come to the banks of streams and puddles to suck water.
The photo example from Nakhon Si Thammarat appears to be an individual that is starting to approach ssp.semanga. I provisionally treat it as the nominotypical subspecies, however, further taxonomic studies with many specimens from Nakhon Si Thammarat to Pattani are needed.
