32.001 [B&F: 0666] Semioscopis avellanella (Hübner, 1793)


Local in ancient small-leaved lime woodland in the southern half of England and in mature birch woodland in Scotland and the northern half of England. There are very few records of this species in Hampshire. most of which have been of single specimens, although it was formerly locally common in the Itchen Valley, in recent years recorded only from Emer Bog in the south and Pamber Forest in the north of the county. Not recorded from the Isle of Wight to date. Wingspan 20-26 mm. Similar to S. steinkellneriana, which see for differences. Larva feeds on Birch and Small-leaved Lime, living within a spun or rolled leaf, over-wintering as a pupa.
