For the county, we have a total of 86 records from 51 sites. First recorded in 1883.
Sutton & Beaumont, 1989: There are few records since the last list (YNU, 1970). Yorkshire is the northern boundary of the species (Skinner, 1984). Consequently it is rather thinly spread and very local.
2012 (CHF): Very local in mature oak woodland and infrequently recorded. There seems to have been some reduction in range as most recent records have been from the south of the county.
