Notes

The butterfly is common in montane and secondary forest at low to high elevations (Alt. 300 - 1700m). Males form flight paths and are frequently found at hilltops. Both sexes visit flowers and I have never seen males come to the streams to suck water.
Although only a few specimens have been examined, the individuals from Phetchaburi and Prachuap Khiri Khan in the northern part of peninsular Thailand seem to be an intermediate population between the nominotypical subspecies and ssp.eranthos. Further taxonomic study and distributional research are needed.
