Resumen
Descripción
The nesting habits and life cycle of Penepodium goryanum (Lepeletier 1845) were studied in 1991 in a central Amazonian blackwater inundation-forest. Nests were obtained from artificial sites for nesting (trap-nests) and consisted of a single cell per cavity, provisioned with cockroaches of the genus Eunyctibora. The characteristics of the nest are given as well as information on the life cycle, seasonality, parasites and prey preferences of P. goryanum. The effects of the flood pulse on the seasonality of P. goryanum are discussed.
