34.014 [B&F: 0910] Sorhagenia janiszewskae Riedl, 1962

 

Notes: Nationally scarce (Na) in heathland and woodland in parts of southern England. In Hampshire by far the most widespread of the three Sorhagenia species, found in places like the New Forest, Emer Bog, Botley Wood and Wickham Common but in the northern half of the county restricted to very few sites. Not recorded from the Isle of Wight to date. Wingspan 10-13 mm. Can only be separated from S. rhamniella and S. lophyrella by dissection of the genitalia. Larva mines twigs of Alder Buckthorn and Buckthorn, living between flowers and shoots spun together with silk.
