For the county, we have a total of 142 records from 83 sites. First recorded in 1883.
Sutton & Beaumont, 1989: Local among alder, there are scattered records from vice-counties 62 to 64. In the southern part of VC63 it has been recorded quite widely and fairly commonly in recent years.
VC61. Scampston Park, 8.6.1991 (HEB); Allerthorpe Common, 13.5.1992 det. HEB (GBS); South Cave, 17.5.1993 det. HEB (DBC). NEW VICE-COUNTY RECORD.
Argus 47, 2001-04:
VC65. Hutton Conyers, 26.5.2001 det. HEB (CHF); High Batts NR., 17.8.2002 (CHF, JCW, SPW). NEW VICE-COUNTY RECORD.
Current status (HEB, 2011): The first county record was from Rothamsted data from Harrogate (VC64) in 1975 but it was not seen again in the county until it appeared at Rossington (VC63) in 1987. Afterwards recorded sparsely in vice-counties 61 and 63 during the 1990s with records increasing during the following decade. Still largely confined to the south of the county but with indications of a northward spread to VC62 from 2009. A moth that will probably be found more widely among birches in the coming years.
