Local in lime woodland in the southern half of England and in mature birch woodland in Scotland and the northern half of England. There are few records of this species in Hampshire. most of which have been of single specimens, although the early flight period may lead to under-recording, and it is not a 'garden' insect. 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.
