Sutton & Beaumont, 1989: Rather rare in Yorkshire with only seven recent sites, however most of these are inland, a change in distribution since the last list (YNU, 1970).
2012 (CHF): Virtually all recent records have been on the east coast from Flamborough northwards though there was a record in 2011 from the south of VC63. There are several old records from Dib Scar/Grass Wood and the surrounding area but it has not been seen here since 1991. It seems to have been lost from some inland sites in other parts of the country.
