Immature stages and biology of Posttaygetis penelea Cramer (Lepidoptera : Nymphalidae : Satyrinae)

Posttaygetis penelea Cramer larvae are common in bamboo understory, present year round, and can be found in a wide variety of habitats. Larvae specialize on woody bamboos within the genus Guadua (Poaceae), and adults are highly associated with bamboo groves. The presence of the host plant is the only important habitat requirement for this species, in that they can be found within bamboo groves in forest habitats, forest edges, and pastures. The immature stages of P. penelea are described and head capsules and chaetotaxy are illustrated. Both larvae and pupae possess distinct features which separate this monotypic genus from the closely related genera Taygetis Hubner and Pseudodebis Forster.
