Sutton & Beaumont, 1989: A very local species in Yorkshire but now recorded from all five vice-counties. It is widely distributed in spruce plantations all over Northumberland and Durham and still increasing its range (Dunn & Parrack, 1986), so it may well also turn out to be more widespread in Yorkshire.
2012 (CHF): Locally common in spruce plantations but not often wandering to other areas. Distinctive when fresh.
