 The species operates on a polygynous system in which one male has the ability to mate with several females in one breeding season.In "Papilio glaucus", that which is of the same genus of this species, the lack of male-male competition, strong rapid flight, dispersed abundant food, and oviposition sights helped to support the idea of mating system based on polygyny.The females are prevented from mating with other males when the male emits a sphragis, which prevents other males from mating with the female, ensuring that only the sperm from this male fertilizes the eggs.
