Stenodema laevigata graswanze grass bug
Stenodema laevigata is a species of bugs from a Miridae family, common in the United Kingdom, and throughout the rest of Europe.
Adults are 7–10 millimetres (0.28–0.39 in) long. The species are of light-green colour, but can come in yellow or brown. The species lacks femoral spurs, and have densely pitted prothorax.
Adults and larvae are both feeding on unripe grains, which includes: Alopecurus, Dactylis, Festuca and wheat. Sometimes, larvae might suck juices from leaves and stems. They start to eat grass seeds and flowers by later development. The larvae hibernates in winter, by living in a soil, and leaf litter. Both males and females mate in spring, with the males being greener than females. The larvae is active from May–July, after which the new generation appears, which will last till next spring.
