Notes

The butterfly is locally common in montane forests at low to moderate elevations (Alt. 100 - 1000m). Males are territorial on trees at hilltops and frequently come to the banks of streams and puddles to suck water.
Kimura et al. (2014) treated the population from peninsular Thailand as ssp.odon, but I could not find any differences from the continental population. Therefore, I consider all populations from Thailand to be ssp.continentalis.
