Yorkshire Status: Scarce and local resident.

Sutton & Beaumont, 1989: There should be no shortage of suitable habitat for this species in most parts of Yorkshire but it is generally only sparsely recorded from all five vice-counties. This is almost certainly a combination of under-recording due to the lateness of season and due to confusion with O. brumata (Linnaeus), for instance G. T. Foggitt reports it to occur annually at Pannal (VC64) with a maximum of twenty-seven in 1981 compared to ninety brumata.

2012 (CHF): Probably widespread in smaller numbers than Winter Moth but under-recorded as few people trap in the winter. There is some confusion with Winter Moth but Northern Winter Moth is larger (little overlap in size), paler and more silky in appearance. It could also be confused with a small late Epirrita species.
