Sorhagenia rhamniella is a moth in the family Cosmopterigidae. It is found in most of Europe, except the Balkan Peninsula.[1]
The wingspan is about 9–10 mm. The head is fuscous, whitish sprinkled.Forewings are fuscous, sometimes somewhat ochreous mixed; large blackish scale-tufts on fold at 1/4, on dorsum before tornus, below middle of costa, and in disc at 3/4; some raised black strigulae towards apex. Hindwings are grey. The larva is greenish; head and plate of 2 black.[2]
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.[3] 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.[4]
