About the Two-Spotted Grass Bug

Stenotus binotatus is a species of plant bug, originally from Europe, but now also established across North America and New Zealand. It is 6–7 mm (0.24–0.28 in) long, yellowish, with darker markings on the pronotum and forewings. It feeds on various grasses, and can be a pest of crops such as wheat.
