Notes

The butterfly is locally not rare in montane forests at low to high elevations (Alt. 300 - 1800m). Males frequently come to the banks of streams and puddles to suck water.
Pinratana, 1985 recorded this taxon from Nakhon Ratchasima, but this needs to be confirmed by examination of the genitalia This species can be distinguished from allied species, particularly xanthopogon and furcatus, by examination of the male genitalia.
