Extract

Published records and recent unpublished field observations on Trox procerus Har. in Asia and Africa are assembled. All stages of the life-cycle are figured, and brief descriptive notes on the egg, larval and pupal stages, are given. It is pointed out that the egg and larval stages have only been recorded from egg-fields of the Desert Locust, Schistocerca gregaria (Forsk.), and that the larvae feed on the eggs of the locust, sometimes causing considerable mortality. In contrast, the adults appear to survive independently of the locust, and it is suggested that the apparent concentration of adults of T. procerus in areas where Desert Locusts are ovipositing is due to their being attracted to the numerous dead locusts that are present in such areas.
