Species Account

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.
VC61. Kilnsea, 4.5.2006 (BRS); Towthorpe, 5.8.2006 (PSu). NEW VICE-COUNTY RECORD.

2012 (CHF): This species remains quite local in the county with most of the records coming from the south of VC62 and the east of VC64 though there are scattered populations in other areas. Occasionally wandering individuals turn up elsewhere for example at Spurn in 2006 and 8. There are no records from VC65.
