For the county, we have a total of 7 records from 7 sites. First recorded in 1883.
Sutton & Beaumont, 1989: Last recorded in the early part of the century by G.B. Walsh in Raincliffe Wood near Scarborough (VC62). This species was scarce, but widespread over much of VC62 in Porritt's day (1883-86, 1904). Other localities included Flamborough (VC61) and Askham Bog (VC64). Like the last species there is also a specimen labelled 'Sheffield' in the Sheldon collection (Garland, 1979).
Current status (CHF, 2011): The last in 1900 - a strong contender for a 'first since Porritt'. Like many lichen-feeding species, this moth is doing well in the south-west and there are small populations not far from our western boundaries.
