description Melanoplus differentialis Overview

Melanoplus differentialis, or the differential grasshopper, is a sizable insect native to North America and a recognized pest of agricultural crops. The species is physically distinguished by its large size and the distinct black, herringbone chevron patterns marking its yellow hind femora. It is highly polyphagous and can consume a wide variety of plants, making it a significant threat to grain, corn, alfalfa, and vegetable crops across the Great Plains and other farming regions. While they are usually solitary, populations can occasionally build up to levels that cause severe economic damage to cultivated fields.
