oa Journal of the Entomological Society of Southern Africa - Notes on the biology and immature stages of Neolophonotus dichaetus Hull in South Africa (Diptera: Asilidae)

Volume 50, Issue 2
  • ISSN : 0013-8789



Observations on the oviposition behaviour of the southern African robber fly Neolophonotus dichaetus Hull are descriptionbed. Females lay their eggs in a frothy secretion between the leaves of certain legumes. This is a behaviour not previously recorded in the family Asilidae. The egg-masses and first-instar larvae, which lack tubercles or pseudopods on the first abdominal segment, are descriptionbed and illustrated. Data on the distribution, seasonal incidence and adult behaviour of the species are presented.
