Species Account

Sutton & Beaumont, 1989: A frequent immigrant to the British Isles, this moth reaches Yorkshire in most years. Numbers are very variable and mainly concentrated near the coast, although there are certain inland localities where it is consistently more common. It has been suggested that this is due to movement from the South of Britain rather than east-west migration (PQW pers. comm.). There is no record from VC65 but it is almost certainly occasionally present.

Argus 47, 2001-04:
VC65. Hutton Conyers, 7, 14 & 20.10.2000, 4.11.2000, 13.10.2004 (CHF). NEW VICE-COUNTY RECORD.

2012 (CHF): Almost half of the county records are from the Spurn area but this migrant can turn up anywhere. There were an unprecedented 221 records in 2006 but numbers have been in single figures each year from 2008 onwards.
