Liorhyssus hyalinus
Hyaline Grass Bug
Liorhyssus hyalinus is a small scentless plant bug in the family Rhopalidae, widely distributed across multiple continents. Adults measure 6.5–7.5 mm and are active year-round in suitable climates. The species is a documented pest of quinoa cultivation in South America, particularly at lower elevations outside the crop's Andean origin, and has been recorded feeding on developing grains of maize and sorghum. Laboratory studies indicate optimal development and reproduction occur at 30°C, with five nymphal instars and thermal requirements of 68.6 degree-days for egg development and 114.8 degree-days for nymphal development.
