description: 31. Locusta migratoria (Linnaeus, 1758)   
(Migratory Locust)  
 Diagnosis: It occurs in green and brown forms in the solitary phase. Adults in gregarious phase were also collected which can easily be distinguished by their yellow colour with dark black marking. The species can easily be identified from other locusts by the absence of prostemal process, the slight yellow tinting of the wings and the black anal veins are distinctive features of the species.   
 Habitats: Though quite strict gramimvorous and capable of causing considerable damage to grain crops, very many plants belonging to different families have been recorded as food. It was collected mainly from millet and maize in large numbers and was observed as being serious pest of millet. It is reported as permanent resident in the solitaria phase on the shores of Chad. Joyce (1952) records this species as eating millet in Sudan. It occurs in wetter areas as nymphs. Under favourable codition, becomes a menace to millet.
