Yorkshire Status: Local resident.

In 1883 Porritt described Crescent as very local, and the comments in Sutton and Beaumont in 1989 seem to agree. Since then however it seems to have expanded in numbers and we now usually receive over 100 records per year. Although much commoner in wet habitats it does wander to other areas and can be encountered over much of the county. It can occur in good numbers in some marshy sites such as Tophill Low NR and Skerne Wetlands when counts can be of over 50 moths. Nationally it seems to have increased in range.

Sutton & Beaumont, 1989: Sporadically found in marshy areas but usually only as singletons.
