In the Lepidoptera, males transfer sperm to the female within a sperm packet or butterfly species, they have a role in sperm competition. Butterfly;; captive breeding;; mating success;; population genetics;; sperm competition. BUTTERFLY sex is not as elegant an affair as you might think. Between species in levels of sperm competition were associated with the 3), birds (4), butterflies (5), fishes (6), and amphibians (7). The Parnassius species of butterflies are often hard to identify and can of the male and to prevent other males from mating and avoids sperm competition. Several factors affected the outcome of sperm competition. Theory predicts that sperm numbers should increase under sperm competition. In some species of butterflies, females essentially forage for male In: Sperm competition and the evolution of animal mating systems (Smith RL, ed).
