The Eastern Tiger Swallowtail (Papilio glaucus) is a species of swallowtail butterfly native to North America. The wingspan ranges from 7.9 to 14 cm (3.1 to 5.5 in) with females being the larger sex. Eastern Tiger Swallowtails are diurnal, and are usually solitary. Adults are known to fly high above the ground, usually seen above the tree canopy.Males seek females by patrolling habitats containing the larval host plants. During courtship, the male and female fly about each other prior to landing and mating. The male releases perfume-like pheromones during courtship to entice the female into mating. The first three instars of the caterpillar are bird dropping mimics, coloration that helps protect it from predators. In later instars, the eyespots on the thorax serve to deter birds. (Wiki.)
