It is a true bug and sucks sap from plants.

It lives on grasses, sedge and rushes and can be a significant pest of cereals.

Mating followed by egg laying occurs on grasses (Poaceae) during late November.

Eggs can overwinter with delayed development (diapause), and then, after being exposed to cold for two or three months, can hatch spontaneously and initiate the next cycle of clonal reproduction.
