Stenotus binotatus
Two-spotted Grass Bug, Timothy Plant Bug, Two-spotted Plant Bug, Slender Crop Mirid
Stenotus binotatus is a grass-feeding mirid bug native to the Palearctic that has become established in temperate regions worldwide, including North America and New Zealand. Adults measure 6–7 mm and show sexual dimorphism in coloration: males are yellow with dark pronotal and forewing markings, while females are greenish-yellow with paler markings. The species is a documented pest of cereal crops, particularly wheat, where its feeding causes distinctive grain collapse and sticky dough problems due to gluten-degrading enzymes.
