Geographical Range
Oriental Region, Moluccas (Holloway, 1998); including India, Thailand, Malay peninsula, Singapore, Borneo, Taiwan, Hong Kong.
In Hong Kong
Distribution: widespread in the New Territories, a single record from Lantau Island; found in secondary forest, plantation woodlands, fung shui woods and shrubland up to 550m elevation.
Status: frequent.
Adult Phenology: on the wing from late February through early December, with most observations from mid May through early September.
Larval Host: Holloway (1998) cites an unpublished IIE report that gives Pteridium (bracken) as the host in Hong Kong. Whilst Pteridium is known from Hong Kong, it is not at all common, and there is a high possibility that another similar looking fern was the actual host.
Notes: This species is predominantly crepuscular (active at dusk and dawn), though it can be seen flying during the day if there is heavy cloud cover. It also has been recorded at mercury vapour light traps. When at rest, the posture of the adults resembles lycaenid butterflies. The flight is usually slow and low, close to ground cover, and typically only for short distances.
