Migratory Grasshopper
Melanoplus sanguinipesAlso known as Lesser Migratory Grasshopper, Red-legged Grasshopper
Migratory grasshoppers are highly adaptable herbivores capable of forming extensive, localized aggregations when population density spikes. Adults undertake sustained low-altitude flights spanning dozens of kilometers to seek out fresh forage across rangelands and croplands. Females deposit tough, soil-bound egg pods in late summer that overwinter safely under the snow, ensuring synchronous emergence the following spring.
