Variation and infraspecific taxa: Little variation known.

Similar species: Unmistakable species.

Habitat: Forest - Subtropical/Tropical Moist Lowland
This species inhabits both primary and secondary rainforest. Males are most commonly seen on hilltops late in the afternoon, where they defend territories from perches a few metres above the ground. Both sexes frequent flowers, usually high in the forest canopy. Adults are extremely rapid flyers. Larvae feed on the fruits and flower buds of Gardenia , Randia (Rubiaceae) and other species, where they may cause significant damage.
(IUCN 2020)

Population: This species appears very local, but is occasionally fairly common.
Range: This butterfly species is distributed widely in South East Asia, where it ranges from northern India, through Indo-China, Hong Kong, Taiwan, Okinawa (Japan), peninsular Thailand/Malaysia to Sulawesi and possibly Borneo (see Taxonomic Notes). Although the species has been recorded from Thailand , Monastyrskii and Devyatkin (2003) did not include the species in their checklist of the butterflies of Viet Nam . Nonetheless, the species has a very large extent of occurrence and, as inhabitants of primary and secondary forest which is still fairly abundant across its distribution, the area of occupancy is also quite large.
