Abstract

The butterfly Phyciodes phaon (Edwards), the Phaon crescent, was reared in the laboratory on its host plant, Phyla nodiflora (L.) Greene, at 27°C with 16:8 (L:D) photoperiod and fluorescent lighting. Eggs are laid in clusters on the underside of host leaves and hatch in about 5 days. Newly hatched larvae aggregate and feed on the underside of the leaf. Later instars disperse on the host plant and continue to feed on the leaves. Larvae develop through five instars based on head capsule, weight, and size measurements. The duration of each instar and the pupal stage were determined. Adults mate 2-3 days after emergence, and females begin laying eggs after 2 more days. The life cycle from egg to adult requires 23-31 days. The butterfly is easy to rear and mating occurs in laboratory cages under artificial lighting. The butterfly has been reared continuously in the laboratory for about 3 years with no evidence of disease in the colony.
