Notes

The butterfly is not uncommon in lowland forests (30–300 m a.s.l.). Both sexes visit flowers. Males are occasionally observed mud-puddling along stream banks and at puddles.
According to Burg et al. (2014), this species was introduced to Thailand by the Phuket Butterfly Garden. It has rapidly expanded its distribution and is now found as far as the Malay Peninsula.
