The border is incomplete or lacking. The underside of both sexes is dirty green. Adults are on wing from June to August. They feed on flower nectar.[2]
The larvae feed on the leaves of Salix species (including Salix reticulata, Salix lutea and Salix planifolia). Second, third, and fourth instar larvae hibernate.[2]
