Sorhagenia rhamniella is a moth in the Cosmopterigidae family. It is found in most of Europe, except the Balkan Peninsula. The wingspan is about 9–10 mm. Adults are on wing from July to August. The larvae feed on Rhamnus frangula and Rhamnus cathartica. They feed from within a slight spinning either in the flowers or the terminal shoots. Sometimes, also young leaves are eaten. Pupation takes place in a pale yellow cocoon near the ground, sometimes between leaves. Larvae can be found from the beginning of May to June.
