Melanoplus flavidus is found in weedy areas of the sagebrush
prairies in Wyoming. It is often associated with sandy soils. The species
is very similar to M. bowditchi in appearance. Eggs overwinter in
the soil and hatch in June. Adults are present from late July to September.
It is a forb feeder with a preference for wild sunflower and ragweed. When
native plant food is scarce it will feed on alfalfa.
