A note on unsuccessful overwintering of larvae of Danaus plexippus (L.) (Lepidoptera: Nymphalidae) in the Blue Mountains, New South Wales

摘要

Fortnightly observations were made on a larval population of Danaus plexippus (L.) at Hazelbrook, New South Wales to provide information on winter survival in the Blue Mountains. The population was decimated in July and August apparently by strong, cold winds. Only small numbers of larvae and pupae survived until September and none produced adult butterflies.
