Mating rituals of butterflies are fascinating, and learning the behavior of each species is one of the most interesting activities of butterfly watching.
The basic function of an adult, male butterfly is to find a mate and copulate. The males of some species constantly patrol for females. Males of other species wait patiently on a perch and fly out to greet anything fluttering by that might be a female. They may even chase a leaf in the breeze because their vision is not keen enough to make identification except at close range. However, one or both sexes are frequently equipped with scent glands which give off pheromones.
