Courtship is more or less the same in all butterflies. Once a female enters the visual field of a male, the male moves quickly to hover over her so that his wings beat rapidly. The female is then induced to land so that the male can attempt to mate with her. There are various ways in which the male entices the female, including visual, olfactory, tactile, and auditory cues. Of particular interest is the use of olfactory cues. Male butterflies produce pheromones from different structures, such as that of the anal fold of the hind wing, that cause the females to perform the appropriate response. Sometimes, however, females choose to reject a male’s attempt at mating, usually due to the fact that she has already mated with a different male. She can do so by either avoiding his approach or, if she lands, she will flap her wings quickly and deliberately all while raising her abdomen until the male flies away. In this way, courtship is primarily a female’s choice. Furthermore, it has been observed that females also produce a pheromone that aids males in determining whether a female has already mated or not.
