Yorkshire Status: Scarce and local resident.

Sutton & Beaumont, 1989: Local in mature broad-leaved woodland with no VC61 records since the 1960s. Described as 'often common' in the previous list (YNU, 1970), this species would seem to have declined. Most widely recorded in the woodlands of the North York Moors' valleys, the only other recent records are from the Harrogate district and Wharfedale in VC64 and the Huddersfield area and the south of VC63.

2012 (CHF): The relief map shows quite clearly that nearly all recent records are from the fringes of the uplands where this species can be locally common in broadleaved woodland bordering on moorland eg 22 at Brimham Rocks on 13.9.2007. It has been largely lost from lowland areas though there are several recent records from Wintersett County Park. The situation has certainly changed from when Porritt described it as in great abundance in the south West Riding in 1904 and occurs everywhere there are woods in 1907. There seems to have been a decline in other lowland areas in the rest of England.
