The butterfly is common in montane forest at low to moderate elevations (Alt.30m - 1600m) and is often found at secondary forest or garden trees in towns. Males are territorial on trees.
Some authors regard taxon apama to be a good subspecies, however the species is highly variable, with individual and seasonal variation seeming to be more pronounced than geographical variation in the continental region. It is also very variable within the same locality. Thus, I treat it as a synonym of garuda.
