The butterfly is uncommon in montane forest at moderate elevations (Alt.400m - 1200m).
In Ranong, both ssp.arata and individuals that very similar to ssp.ace are found sympatrically, but the upper surface coloration is close to that of arata. This area is considered to be a transition zone for both subspecies.
