An uncommon butterfly occurs in lowland to mid hills of wet zone forests. It is a migratory species and Ormiston noted of ‘flights’ of Ceylon snow flats with Water snow flats together at Haldummulla toward west (Ormiston 1924). But usually it flies a short distance and settles with its wings expanded on the under side of a leaf. Its larva feeds on Heen Kabarossa (Smilax zeylanica) of family Smilacaceae. Female has more white on its hind wings than male(figured here).
