subfamily - CHARAXINAE
Charaxes marmax, male, Chilapata, West Bengal, India   Adrian Hoskins
The Charaxinae are a group of large, robust Nymphalids characterised by their rapid and powerful flight, falcate apexes, and a habit of feeding at dung and carrion. They are represented in Africa by Charaxes, Euxanthe and Palla; in the neotropics by Consul, Memphis, Prepona and Agrias; and in the Oriental and Australian regions by Polyura and Charaxes.

Charaxes marmax is found in north-east India, Myanmar, Laos, Cambodia, Thailand and peninsular Malaysia.

This species is found in rainforest and humid deciduous forest at elevations between sea level and about 600m.

Adult behaviour
Males often gather in dozens to feed at mammalian dung, from which they obtain vital salts which are passed to the females during copulation. They also feed at urine, and less commonly at rotting fruit on the forest floor. During spells of hazy sunshine they commonly bask on boulders or large stones, with their wings almost fully outspread. If disturbed they fly up and settle on tree foliage, and rest with the wings erect or half open. Both sexes fly to the highest point in the vicinity, often a forested hilltop, where courtship and copulation take place.
