Sutton & Beaumont, 1989: Now restricted mainly to moorland and sea cliff areas in Yorkshire. Although there are more records than in the last list (YNU, 1970) few of these are post 1980 and it may still be in decline. However, few people take traps to these remote areas in the later months of the year and it may just be under recorded.
2012 (CHF): We have two main populations of this moth, on the east coast (particularly in the Filey and Flamborough area but also up the coast at Skelton) and in the western Dales. There have been no records from VC63 since 1978. It is undoubtedly under-recorded, particularly in the Dales, as those who trap in October and April record this species on a regular basis. It was noted frequently from 1990-93 at Colt Park when the Rothamsted trap operated here and is regular at Malham Tarn. The females over-winter and fly again in the Spring.
