    Rhogogaster chlorosoma can reach a length of 10–13 millimetres (0.39–0.51 in). It is one of the various green sawflies with a variable black pattern, but in this sawfly the black markings on the top of the abdomen are absent or quite reduced. Like other sawflies, this species lack the slender "wasp-waist" between the thorax and abdomen.

    Adults can mostly be encountered from May through July. They mainly feed on pollen and nectar of Heracleum sphondylium as well as small insects. The nocturnal larvae are polyphagous, feeding on the leaves of a variety of woody and herbaceous plants, mainly Sorbus, Quercus robur, Salix, Corylus avellana, Stellaria, Filipendula ulmaria, Alnus glutinosa, Rubus and Populus.
