Species Account

Sutton & Beaumont, 1989: Quite widespread and now recorded from all five vice-counties. The spate of VC63 records in the 1970s and from further north in the early 1980s would suggest periods of dispersal and colonisation of new sites.

2012 (CHF): Thinly distributed all across lowland Yorkshire in small numbers. Increased records in the last few years with 41 records in 2010 and 53 in 2011.
