For the county, we have a total of 39 records from 22 sites. First recorded in 1968.
Sutton & Beaumont, 1989: First found in Yorkshire by Dr S.L. Sutton at Pilmoor (VC62) and Aberford (VC64) in 1968 (Jackson,1969), there are now three more recent records for this species.
VC63. Maltby Far Common, 2.8.1999 (HEB). NEW VICE-COUNTY RECORD.
2012 (CHF): The range of this species is restricted by its foodplant, Wood Small-reed, though the plant seems to be doing well and expanding a little. Our Yorkshire records are the most northerly in the country. Very local in the county with most records coming from the Allerthorpe and Pilmoor areas. The RIS trap at Tadcaster used to report it regularly in the 1990s. Wandering individuals sometimes turn up at Spurn. This species should be looked for in old damp woodland in the centre of the county as more colonies may exist undetected.
