Grasshopper \Grass"hop`per\, n.
   1. (Zo["o]l.) Any jumping, orthopterous insect, of the
      families {Acridid[ae]} and {Locustid[ae]}. The species and
      genera are very numerous. The former family includes the
      Western grasshopper or locust ({Caloptenus spretus}),
      noted for the great extent of its ravages in the region
      beyond the Mississippi. In the Eastern United States the
      red-legged ({Caloptenus femurrubrum} and {C. atlanis}) are
      closely related species, but their ravages are less
      important. They are closely related to the migratory
      locusts of the Old World. See {Locust}.
