Sutton & Beaumont, 1989: Not recorded since Porritt (1883-86). He gave records from Guisborough, Scarborough (VC62), Sheffield (VC63) and York (VC61/62/64).
Argus 58, 2009: The anticipated recolonisation of the county has now taken place and this moth is likely to be discovered in several more areas. These are the first confirmed records since the 19th century though there was an unconfirmed one from Wharfedale in 2004.
Current status (CHF, 2011): Porritt listed Guisborough, Scarborough, Sheffield and York as sites for this moth, but there were no 20th Century records. A quite remarkable range expansion has taken place recently up the western side of the country and throughout Scotland. This population has gone on to colonise Northumberland and Durham and then spread south to VC62 in 2009. In 2011 there was evidence of further spread with records in VCs 62, 63 and 64.
Argus 66, 2012: Significant spread of range and increased numbers in the north of the county plus a single record from the south.
