Yorkshire Status: Scarce and local resident.

Sutton & Beaumont, 1989: This mountain species still occurs at its best known Yorkshire site, Malham Tarn (VC64), and has recently been reported from other localities, suggesting it may be fairly common at high altitude in the north and west of the County. Skinner (1984) mentions that a form 'that lacks the dark red central band occurs frequently in parts of Yorkshire'. Skinner (in litt. 1989) gives details of three separate records of this form, involving seven specimens. Two were from the Grassington area (VC64), one from Keld (VC65). One record was published (Bretherton, 1975).

Beaumont, 2002: VC64. Malham Tarn, annually in early August, 1991-2000 (DB); Low Bentham, 3 & 8.8.1994 (TMW).

VC65. Low Row, four 1990-1996 (TMW).

2012 (CHF): A big recent increase in records of this upland moth probably reflects more observer effort on the higher ground rather than a genuine increase. It is still commonest in the north and west of the county with few records in VC63 and just one in VC62 (Guisborough 1994). It can occasionally be found on lower ground for example Bellflask in 2010 and Nosterfield in 2011.
