Title :

Adult behaviour of Orachrysops niobe (Trimen) (Lepidoptera: Lycaenidae)

Abstract :

Observations have been conducted over several years at the Brenton Blue butterfly reserve (BBBR) on the adult behavior of O. niobe, as part of a larger study of the ecology of the species.  The nectar sources of both sexes are recorded, and assessed not to be a limiting factor for population size.  The patrolling behavior of males and the courtship and mating behavior of both sexes are described.  Observations of female oviposition behavior and preferences are combined with data on egg densities to conclude that neither ants nor previous oviposition history influence female choice of host plants, which appear to be detected by visual rather than olfactory cues.  The incidence of adult dwarfism is recorded and the low natural occurrence compared with results of captive breeding.  The annual phenology of the development stages of O. niobe is recorded and unusual features such as an occasional third brood discussed.
