This butterfly's wings show fine black lines on a white background that resemble cracks running through a stone wall, with soft orange-brown spots along the margins. It flies with a light, gliding motion low over vegetation.

Caterpillars feed on fig and other Moraceae leaves, and adults commonly gather at damp ground or puddles to draw up minerals. It ranges from hill forests of the Indian subcontinent and Southeast Asia through southern China, Taiwan and Japan's southern islands.
