These grasshoppers are named for their striking, red hind tibiae. In much of North America, especially across the northern half of the US and in southern Canada, this is one of the most commonly encountered species of grasshoppers. They are at home in grassy and weedy places, particularly sunny, moist, low areas like meadows and prairies, vacant lots, yards, along roadsides, in river floodplains, and in cultivated fields, old fields, and crop borders. They feed on a wide range of plants and are sometimes in such high numbers that they can become a garden or crop pest. Before the females die off, they will deposit several egg masses that contain up to 20 eggs each in the soil. The eggs overwinter and hatch in the spring. The nymphs will reach adult size by August or early September.
