Abstract

Life history data for the cyrtacanthacrid locust Austracris guttulosa in Queensland were compiled from field observations over the period 1971-1976. Nymphs were present from November to April inclusive and adults throughout the year, with adults from overlapping generations present in January and February. A. gurtulosa was univoltine, adults remaining sexually immature throughout the dry season (April to October). Sexual maturation was related to the higher temperatures, humidities and day lengths from September/October onwards and resulted in depletion of fat body. Sexually mature adults died out by February.
