The brown locust is a small species relative to most other plague locusts, but it has a very pronounced phase polymorphism and presents a serious economic problem. In its solitarious phase it occurs over an area of about 100,000 square miles of desert and semi-desert steppe country. This comprises parts of the Cape Province, the Western Orange Free State and the southern parts of South West Africa with an annual summer rainfall of between 5 and 15 inches. During uncontrolled plagues swarms are known to have emigrated and bred at one time or another over most of Southern Africa to as far north as the Zambezi river (Faure, 1932; Lea, 1968).
