Blissus leucopterus, also known as the true[clarification needed] chinch bug, is a small North American insect in the order Hemiptera and family Blissidae.

Due to their small size, chinch bugs are hardly noticeable, so they become problems, since they are considered pests that feed on stems of turfgrass [4][5] and grain crops.

[7] Chinch bugs feed on plants, both wild and cultivated, belonging to the grass family, such as wheat, rye, barley, oats, and corn.

The adults overwinter in any type of shelters they can find, including in hedgerows, road sides, bushy fence rows, edges of woodlands, and soybean stubble, under tree barks and bunch grass, and inside field mice nests.

Their natural predators include the big-eye bug (Geocoris bullatis), and the tiny wasp (Eumicrosoma beneficum), which feed on or parasitize them.

Throughout the 20th century, the chinch bug was a major pest to farmers, as it quickly decimated corn or wheat fields.
