Sutton & Beaumont, 1989: Appears now to be rather local with recent records from four vice-counties. Although we have no VC65 record, it has been recorded in the Rothamsted Insect Survey trap in Middleton-on-Teesdale (VC66) (Dunn & Parrack, 1986) and may well occur along our northern boundary in this area.
