Yorkshire Status: Scarce and very local resident.

Sutton & Beaumont, 1989: Strensall Common (VC62) is a nationally famous site for this species and here its status has been charted from 1894 to the present by the York and District Field Naturalists' Society (JP pers. comm.). With probably only one other English site and a few in Scotland it is heartening that it is still plentiful at Strensall, with records right up to 1988.

Beaumont, 2002: VC62. Strensall Common, continues to occur commonly.

2012 (CHF): A fire in the autumn of 2009 destroyed one of the main areas for the moth on Strensall Common and two cold winters have not helped the foodplant, so numbers have been lower than usual for the last two years. This species continues to be closely monitored. There is a single record from upper Teesdale in 1976 but the moth has not been refound there.

Argus 84, 2018: Examination of old collections has proved that this species used to occur at Askham Bog in the 19th century and six specimens have been located. We therefore have a rather late vice-county record to report.
