VC65. High Batts, 30.10.1983 (SPW); Hutton Conyers, 19.8.1999 (CHF). NEW VICE-COUNTY RECORD.
2012 (CHF): Porritt only knew of one record of this species, in Leeds in 1876. It then became quite frequent at a number of sites between 1941 and 1953 before disappearing until the 1970s when it appeared again and spread across the county. It is now widespread apart from the north-west of Yorkshire and has spread up through Northumberland into the south of Scotland. We usually receive between 50 and 100 records per year and numbers seem to be stable.
