Immature stages of Adelpha malea goyama Schaus (Lepidoptera: Nymphalidae, Limenitidinae)

Abstract

The immature stages of Adelpha malea goyama Schaus are described from the Estação Ecológica do Caiuá, Paraná State, Brazil. The species uses the native liana Arrabidaea mutabilis Bur. & K. Schum. (Bignoniaceae) as larval hostplant in the study site. Isolated eggs are laid on leaf tips, and are similar in shape to those described for other species of Adelpha Hübner. Larvae pass through five stadia during 21 days, and first to third instars construct frass chains. Later instars rest on the upper leaf surface, and their body is covered by rigid branched scoli. The general profile of the pupa is elongated, with short head horns projecting laterally and with segment A2 projecting and curved anteriorly. Comparisons with closely related species of Adelpha are not conclusive, and more species in the genus need to be reared before a clear pattern of the variation in immature morphology becomes evident.
