Sutton & Beaumont, 1989: Still regularly recorded from the north-east of the County, this species shows no sign of change in its distribution in Yorkshire although wych elm is disappearing from many sites (PQW pers. comm.). The future status of the moth is therefore uncertain.
Argus 47, 2001-2004: More widely reported than for many years, the VC64 records are the first from that vice-county since a record from Knaresborough (Porritt, 1904).
VC65. Magdalen Wood, 31.5.2003, 14.7.2004 (CHF, JCW). NEW VICE-COUNTY RECORD.
2012 (CHF): Local in the county. Since 1989 populations in the north-east have remained healthy and it is also now doing fairly well in the area around Ripon. Numbers may have dropped a little but it can still be locally quite common for example 82 trapped at Hackfall Woods on 9.7.2010. Sometimes disturbed in the daytime.
