The butterfly is locally common in montane forests at low to moderate elevations (Alt. 350 - 1000m). Males are territorial on trees at hilltops.
Some specimens from northern Thailand show a slightly transition to ssp.ephebus. Curiously, with the exception of Pattani and southwards, it has not been found in peninsular Thailand. Further distributional research is needed.
