Comparative morphology of the last instar and pupa of Scolecocampa medara (Schaus) (Lepidoptera, Erebidae), with redescription of the adult

Larvae and pupae of Scolecocampa medara (Schaus) were collected in galleries inside decaying tree trunk where larvae were found feeding. Descriptions and illustrations of the last instar and pupa, as well as information on the natural history of S. medara are here provided. The larval chaetotaxy is compared with two closely related species, Scolecocampa mochisa (Schaus) (Scolecocampinae) and Hyponeuma taltula (Schaus) (Herminiinae). In addition, we provide a redescription of the adults, including the morphology of the male and female genitalia, with a brief taxonomic history of Scolecocampa Guenée and related genera.
