The butterfly is not rare in montane forest at moderate to high elevations (Alt. 500 - 1800m) and is frequently found on the hilltops. Male makes a territory on the trees.
The population in W.Thailand tends to have whiter and larger white markings on the UpF, especially subapical white spots. Further taxonomic study is needed.
