Entephria polata is a moth of the Geometridae family. It is found from Fennoscandia to north-eastern Siberia. It is also present in northern North America. The wingspan is 23–32 mm. Adults are on wing in July. The larval foodplants were unknown for a long time. But Itämies and Várkonyi reported (in 1997) the larvae on Empetrum nigrum ssp. hermaphroditum. The larvae were observed to live on the buds of the plant in early summer. Several pupa of this species have been found in a web under rocks.
