Habitat: Primarily sandy areas.
Host: Forbs, grasses.
Adults Present: July-September.
Notes: Male cerci narrow at middle, somewhat bone-shaped; pronotum with a distinct pale stripe on each side; hind tibiae green or red; tegmina long; distinguished from M. packardii by details of male aedeagus. Not economically important. A possibly distinct species closely related to foedus is Melanoplus fluviatilis Bruner. Specimens from the Rio Grande bottoms near Albuquerque may belong to this species. Fluviatilis keys to foedus but may differ in being rougher and smaller and by its riparian habitat. The status of fluviatilis is uncertain.
Reference: Helfer 1953, Capinera and Sechrist 1982.
