Similar species
Chestnut Streaked Sailor
It is a common butterfly that occurs from sea level to about 3000 feet elevation. It prefers lightly wooded areas with scrub jungle, but is seen everywhere. It inhabits much drier areas than the Chestnut Streaked Sailor.
Its flight pattern is very distinctive – a few wing beats followed by a spell of sailing with its wings held horizontally. It stops the power stroke of its wings abruptly when the wings reach the horizontal plane and keeps them locked in that position for the rest of the glide before it flicks them once again. It usually flies low to the ground and is fond of bright sun. In dappled shade, its pied markings conceal it quite well and may confer some advantage to escape predators. In the early morning hours, it often basks in the sun with its open wings, and after warming up, flies about a great deal in search of nectar, ripe or spoiled fruits, fermenting juices or exudates from trees. While feeding, it rhythmically opens and closes its wings. When it roosts, it does so with its wings held above its back, making it less conspicuous to predators. It is occasionally attracted to damp soil.
