Males of the barred sulphur, Eurema daira, perform a unique 'wing-waving' display in courtship. This display and its significance are described in detail from motion picture records of successful and unsuccessful courtships. Wing-waving is done in bouts and is a requisite part of successful courtship. The display appears to have evolved in response to female choice for males that clearly announce their species identity; there are two other pierid species of very similar size and colour pattern that occur sympatrically with E. daira.
