The butterfly is locally common in montane forest at low to moderate elevations (Alt.10m - 1600m).
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.
