Yorkshire Status: Rare and very local resident.

This seems to have never been a common moth in the county. Porritt commented "not a common species" and listed records from Hornsea, Pontefract and York. Our moths are the northern outpost and this appears to have always been the case. It is a species of damp woodland and heathland. It is very local in the county with isolated populations at Spurn, Strensall Common, Allerthorpe Common and the eastern part of VC63. It was also recorded at Askham Bog in 2019. Our population is probably stable, and it has appeared in the county in every year since 2015, though only in very small numbers. All records are of just one or two moths, suggesting that it does not come strongly to light.

Sutton & Beaumont, 1989: A very local species preferring fenland, damp woodland and marshy places. Only recorded from Strensall Common (VC62) for many years, it has now also been recorded from Allerthorpe Common and Everingham (VC61).

Recorded in 13 (7%) of 200 10k Squares.
First Recorded in 1880.
