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.
Stenotus binotatus is a fairly large plant bug (6–7 millimetres or 0.24–0.28 inches long), which is somewhat variable in appearance. The insect's sides are roughly parallel, and the colours depend on both the animal's sex and its age, the markings becoming darker and stronger with increasing age. Males are mostly yellow, with darker markings on the pronotum and forewings, which females are greenish-yellow with paler markings.
S. binotatus is native to Europe but has been introduced to temperate regions around the world. It is common "throughout the northern and central U.S. and southern Canada", and it has been introduced to New Zealand, where it now found almost throughout the country.
Both the nymphs and adults feed on the inflorescences of grasses, especially timothy-grass (Phleum pratense). In New Zealand, S. binotatus has been collected from a large variety of plants, including the grasses brown top, Yorkshire fog, cocksfoot, wheat, barley and maize, and many other plants (including rushes, Hypericum, mānuka, rātā, Nothofagus, Coriaria, Olearia, Muehlenbeckia, Carmichaelia, Larix decidua, Eucalyptus, Melicytus ramiflorus, Coprosma robusta, pōhutukawa, hemlock and nettles).
