Chinch Bugs

Chinch Blissus leucopterus also known as the true Chinch Bug is a small (about 1/8th inch (3-4 mm)) North American insect in the order Hemiptera and family Lygaeidae.Adult Chinch Bugs are black with opaque wings; wing length varies from as long as body to only one-third length of body, and each wing bears a distinctive, triangular, black mark. Nymph are wingless and smaller than adult but similar shape; head and thorax brown; eyes dark red; abdomen pale yellow or light red with black tip. They feed on forage, lawn, and wild grasses plus crop plants, including wheat, corn, sorghum, oats. Chinch bugs pierce the plant with their mouth parts and suck out the plant sap. This feeding prevents normal growth and results in dwarfing, lodging, and yield reduction. Severe infestations during early development may cause plants to wilt and die prematurely.
