   1. (Zool.) 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

   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}.
