Mating and young

After mating, the male Parnassines produce a glue-like substance that is used to seal the female genital opening and prevent other males from mating. They lay individual eggs on the underside of the leaves of their food plants. There is no parental investment once the eggs have been laid.

The pupae are typically attached to the substrate by the cremaster but with head up held by a silk girdle. The Apollos, however, pupate in debris on the ground and also build a loose cocoon. In the temperate regions, the winters are passed in a pupal diapause stage.
