Yorkshire Status: Rare and very local resident.

Sutton & Beaumont, 1989: Formerly confined to Grass Wood (VC64). This species has suddenly appeared in several new localities in North Yorkshire and being such an unmistakable day-flying moth it is unlikely to have previously been overlooked. It has been recorded from one site in the south of VC63 in recent years. The source of this colony is possibly the Derbyshire dales.

2012 (CHF): Day-flying in upland woodland in the north west of the county. There have been increased numbers of records in recent years. Two old records in the 1970s from Thorne Moors are a bit of a mystery being a long way from other populations.

Recorded in 19 (10%) of 200 10k Squares. First Recorded in 1880. Last Recorded in 2022. Additional Stats
