Sutton & Beaumont, 1989: Rather local in Yorkshire, and rare in industrial areas where lichens are scarce. In the high pastures of the Dales the larvae live in dry stone walls, coming out at night to feed on the lichens on the stones.
2012 (CHF): This is very much a moth of the Yorkshire Dales and the North York Moors, especially in calcareous areas. In the south and east of the county it is much more unusual, though there are several records from Spurn. Sometimes it can be numerous eg 424 on 3.7.2009 on the YNU outing to Kettlewell.
