The butterfly is locally not rare in montane forests at low elevations (Alt. 30 - 450m).
The nominotypical subspecies is found from Yala to Narathiwat in the southernmost part of Thailand, though individuals intermediate between ssp.dama and ssp.elopura are more frequently observed. Males have a narrower black marginal border on the UpF that is less than 0.5 mm wide or a thread, and the ground colour on the underside of both wings is brownish-grey, as in ssp.elopura. However, it is half fuscous in space 6 on the UpH. This area is considered to be a transition zone between the two subspecies.
