Life cycle and ecological considerations on Osmilia violacea (Th.) (Acreiddae, Ommatolampinae)

Abstract

This paper deals with some biological considerations on Osmilia violacea, its preimaginal life and two characters which permit a clear and relatively easy separation of the different instars: the number of antennal segments of the basal group and the number of ocular bands. Furthermore, data on sexual maturity, copulation, oviposition, egg-pods and duration of the embryonal period are given.
