Species Account

Sutton & Beaumont, 1989: Not definitely recorded since Porritt (1883-86) when there were records from Doncaster, Huddersfield, Sheffield (VC63) and York (VC61/62/64). On map 178 in MBGBI 9 a post 1960 record is shown for 10 km square TA07 (VC61) which is in error (PQW pers. comm.). There has been an unconfirmed record from the High Batts Nature Reserve near Ripon on 17.4.1987 (SPW), but unfortunately the specimen was not retained for examination.

Argus 58, 2009: A small but totally unexpected influx of this species in April [2009]. The first confirmed Yorkshire records since the 19th century. These records will be of migrants, though it is resident in the south of the country.
VC61. Spurn, 10.4.2009 (BRS); Easington, 12.4.2009 (MJS). NEW VICE-COUNTY RECORD.
VC64. Burley-in-Wharfedale, 14.4.2009 (P&AR). NEW VICE-COUNTY RECORD.

2012 (CHF): There was an influx of this moth into the country in 2009 and three made it to Yorkshire with records at Spurn (10.4.2009), Easington (12.4.2009) and inland at Burley-in-Wharfedale (14.4.2009). It is resident in oak woodland not far from our border in north Lancashire and south Cumbria so it is not impossible that it lurks undiscovered in the west of VC64.
