Two houseflies (Musca domestica) mating. One of the most widely distributed insects all over the world, females are ready to mate some 36 hours after emerging from the pupal stage. Normally the female mates only once, and will lay approximately 500 eggs in several batches of about 75 to 150 each.Photo credit: Muhammad Mahdi Karim
