Species Account


Sutton & Beaumont, 1989: Widely distributed but seldom common in vice-counties 61 to 64, but only recorded once from the south and occasionally from the middle of VC65. This species appears to prefer the richer or calcareous soils, and consequently is generally absent on moors and heaths.

Current status (CHF, 2011): Currently in national decline and has been lost from many areas of central Yorkshire. Numbers in VC61 however have increased and this population is becoming nationally important.
