Melanoplus sanguinipes (Fabricius, 1798) - (devastating grasshopper)
This is one of the most damaging grasshopper species in western North America. It lives mainly in grasslands, but attacks various crops, like small grains, alfalfa or canola. Outbreaks where grasshoppers reach high densities and adults form swarms have been reported periodically. Eggs are laid in the soil during autumn and hatch the following spring when rains start. The 6 nymphal stages are completed within 6 weeks to 2 months. In warmer regions there may be 2 generations per year. The adults are up to 5 cm long. The structure of the male genitalia is diagnostic for distinguishing it from closely related species.
