The second and last segments bear each a pair of spiracles, and the fifth and following segments have each a spiny pad below. The pupa case is formed from the last larval skin. The imago emerges a fortnight after laying, becomes sexually mature in a week, and lays its first batch of eggs four days after mating. It may deposit half a dozen.
