Sutton & Beaumont, 1989: Records in the last list (YNU, 1970) suggested this species was confined to upper Wharfedale and the southern edge of the North York Moors. It has become considerably more frequent in recent years but is still rather local in woodland, usually on limestone.
Argus 52, 2006: The Towthorpe (near Driffield) record would appear to be the first record of a second brood in Yorkshire.
