Yorkshire Status: Rare and very local resident.

This species was unknown in the county in Porritt's time though may well have been here undetected. The first confirmed county record was not until 1968. Its range is restricted by its foodplant, Wood Small-reed, though the plant seems to be doing well and expanding a little. Most of the British population is in the east Midlands, East Anglia and some southern coastal counties.Our Yorkshire records are the most northerly in the country. Our small populations are very local 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 and at other sites in VC61. Some coastal records may be migrants. This species should be looked for in old damp woodland in the centre of the county as it highly likely that more colonies may exist undetected. The vast majority of our records are of single moths, though nine were caught at Allerthorpe Common on 18/7/2018. It is difficult to comment on how well it is doing in Yorkshire, but it appears that numbers are probably stable.

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.
