There are approximately 1000 species of grasshoppers in North America. The common types found in the United States are the differential grasshopper, the redlegged grasshopper, and the twostriped grasshopper.
Full grown grasshoppers range from 3/4" to 1 1/2" long and vary slightly in color depending on species. The differential grasshopper is brownish-yellow or olive green color with black markings. The redlegged grasshopper has a reddish-brown back, a yellow belly, and bright red hind legs – hence the name. The twostriped grasshopper looks similar to the differential grasshopper with greenish-yellow overall coloring and brown/black markings.
Grasshoppers live throughout the continental United States. However, they are concentrated in areas of the country like Montana and Minnesota and south into New Mexico and Texas.
Grasshoppers nest in several different types of grasses including bahia grass, Bermuda grass, crab grass, nut grass and wood grass. They also feed on dogwood, hickory, citrus and palm trees.
Plant flowers such as marigolds, calendula, sunflower, daisy, alyssum, or dill nearby to attract beneficial insects. A number of insecticides also effectively kill grasshoppers. Look for products containing carbaryl or permethrin.
No, grasshoppers are not harmful to humans. However, they can be harmful to crops. Consult a pest control specialist if you spot a grasshopper population that needs to be controlled.
