Sutton & Beaumont, 1989: There are scattered records from all five vice-counties, however on map 8 in MBGBI 1 all Yorkshire records are shown as unconfirmed. There are confirmed records from the south of VC63.
Beaumont, 2002: In 1989 the only confirmed records were from the south of VC63, there have been a number of further records from vice-county together with the following:-
VC61. Skipwith Common, 17.4.1994 (GBS); South Cave, 27.4.1994 det. HEB (DBC). NEW VICE-COUNTY RECORD.
VC62. Strenshall Common, 26.4.1989 (MRB). NEW VICE-COUNTY RECORD.
2012 (CHF): We now have confirmed records from all five vice-counties. The adults can be tricky to separate from other birch-feeding Eriocrania species particularly cicatricella. With care these species can be easier to identify from their larvae which all form blotches on birch leaves. The head of the larvae of E. unimaculella is brown anteriorly and black posteriorly. The first thoracic segment has indistinct dark spots. The mine is usually vacated by mid May.
