908 Sorhagenia rhamniella
(Zeller, 1839)Wingspan c.9-10mm.
In common with other British Sorhagenia species, this species needs identifying by reference to the genitalia.
Rather local, it frequents calcareous districts and damper situations in the fens of East Anglia and central southern England. Adults are on the wing between July and August.
The larva feeds on alder buckthorn (Frangula alnus) and buckthorn (Rhamnus cathartica), in a slight spinning either in the flowers or the terminal shoots.
