For the county, we have a total of 7 records from 7 sites. First recorded in 1883.
Sutton & Beaumont, 1989: There has only been one recent record of this moth in Yorkshire. Previous records are very scant - it was suggested in the YNU 1970 list that the record near Bradford (VC63) was probably an accidental introduction and Porritt (1883-86) only recorded it once, from Richmond (VC65). Until 1984 it was doubtful whether this species was still breeding in Britain (Skinner, 1984). However it was then discovered to be resident in two woods in Northumberland (Dunn & Parrack, 1986) in 1984 and 1985. Both woods have a mixture of coniferous species and trees of different ages, which could be the key to this species' survival. Whether our recent record is from an as yet undiscovered colony or just a vagrant is uncertain but it would certainly be worthwhile to search for this species in suitable Yorkshire woodlands.
2012 (CHF): We have one recent record of this species from mixed woodland at West Tanfield in 2004 (confirmed A.M. Riley). A large and fairly distinctive species.
Argus 69, 2013: Only the sixth county record. This scarce spruce-feeding species could be either native, introduced with conifers or a migrant.
