Mating of Flesh Flies

Sarcophagidae (from the Greek σάρξ sarx = flesh, φαγεῖν phagein = to eat) are a family of flies commonly known as flesh flies. They differ from most flies in that they are ovoviviparous, opportunistically depositing hatched or hatching maggots instead of eggs on carrion, dung, decaying material, or open wounds of mammals, hence their common name.

☮ Within two to nine days after adults emerge from the puparia, copulation occurs.
☮ There is no known courtship ritual for this species; males have no specialized ability to identify females of the species.
☮ In fact, it has been noted that males will copulate with other males and dead flies.
☮ Additionally, the same male has been observed mating with the same female multiple times suggesting that this species does not have a pheromone or other cues to detect previous insemination as has been observed for other Dipteran species.

P.S.: We've always known that the larger of the species was the female. We saw it all the time when we caught them mating. This is a first that the female (read: the submissive) is smaller.
