Any one of numerous species of long-winged, migratory, orthopterous insects, of the family {Acridid[ae]}, allied to the grasshoppers; esp., ({Edipoda migratoria}, syn. {Pachytylus migratoria}, and {Acridium perigrinum}, of Southern Europe, Asia, and Africa. In the United States the related species with similar habits are usually called {grasshoppers}. See {Grasshopper}. [1913 Webster]

Note: These insects are at times so numerous in Africa and the south of Asia as to devour every green thing; and when they migrate, they fly in an immense cloud. In the United States the harvest flies are improperly called locusts. See {Cicada}. [1913 Webster]
