Distribution and habitat

This species is present in Southeast Asia (Borneo, Peninsular Malaya, Singapore, Sumatra, Bangka Island, Sulu Islands, Belitung).^[2] These butterflies inhabit tropical forests among undergrowth and on shaded trails.

Description

Lexias canescens has a wingspan of about 10 cm (3.9 in). These butterflies have dark brown and whitish or yellow-spotted upper surface of the wings, which is an efficient camouflage against predators. Caterpillars are pale green with long spinous bristles.

The male of Lexias canescens pardalina is rather similar to a small female of Lexias pardalis but the underside of its hindwings shows a yellow-washed color.^[3]

Biology

Adults can be found year-round, with a peak from June to September.^[4] They mainly feed on organic matter and rotting fruit.
