The Differential Grasshopper ranges widely in North America, where it is considered a severe pest of crops. A dense swarm of adults can destroy a young cornfield in just three or four days. Crops impacted by both nymphs and adults include grains, corn, alfalfa, soybeans, cotton, various vegetables, and deciduous fruit trees.

It can be found in low damp waste places such as borders of streams, and margins of lakes and ponds and also along fence rows and cultivated fields, especially in tall lush vegetation.
