About Rhogogaster chlorosoma (Benson, 1943)
Rhogogaster chlorosoma (Benson, 1943) is a species of green sawfly. Adults reach a body length of 10 to 13 millimetres (0.39 to 0.51 inches). This species is one of multiple green sawflies with variable black patterning, but it has no or very reduced black markings on the top of its abdomen. Like all sawflies, it does not have the narrow "wasp waist" between the thorax and abdomen. It can be distinguished from similar species: Rhogogaster viridis has clear black marks on the upper surface of the abdomen, while Rhogogaster punctulata has black dots along the sides of each abdominal segment. Adults of this species are most commonly found from May through July. They feed mainly on pollen and nectar from Heracleum sphondylium, as well as on small insects. The larvae are nocturnal and polyphagous; they feed on the leaves of many different woody and herbaceous plants, most commonly Sorbus, Quercus robur, Salix, Corylus avellana, Stellaria, Filipendula ulmaria, Alnus glutinosa, Rubus, and Populus. Rhogogaster chlorosoma is widespread across most of Europe. It can typically be found in hedgerows and vegetated mountain areas.
