Reproductive behaviour and larval development of Prionyx thomae (Fabricius) from Brazil (Hymenoptera: Sphecidae).

Abstract

The nesting behaviour and larval development of the solitary wasp Prionyx thomae (Fabricius) are described. Observations on male behaviour are also provided. The study is based on observations carried out in four places of the Rio de Janeiro State (southeastern Brazil). The following species of grasshoppers (Orthoptera: Acrididae) are reported as prey: Orphulella punctata (De Geer), Rhammatocerus pseudocyanipes Assis-Pujol, Abracris flavolineata (De Geer) and Ronderosia bergi (Stål).
