Notes

The butterfly is locally very common in montane forest at moderate elevations (alt.1200m - 1300m) and is frequently found on top of mountains. Males are territorial on trees at hilltops and fly in circles for long hours in their territorial space.
The populations from W.Thailand and Dawna range, S.Myanmar have similar shape of tail to those of ssp.nagamasai. Further taxonomic study is needed.
