Yorkshire Status: Local resident.

Barred Chestnut is rather local in Yorkshire and seems to have always been so. In 1883 Porritt wrote "The Bradford district seems to be headquarters for this rather local species" and in 1907 wrote "common in many of the south West Riding woods but elsewhere only recorded from Richmond". This is a woodland species which is much commoner in upland areas. It is absent from much of VC61 and is rare in the east of VC63 apart from occasional records from Thorne Moors. Nationally it has been lost from many areas of the south-east of England, but it is doing much better in Scotland. Numbers in the county seem to fluctuate from year to year, but the population is probably stable. In good habitats, counts can reach double figures, the maximum being 14 at Brimham Rocks on 25/8/2010. It is rather similar to some other Diarsia species but has a broader and more curved forewing giving it a rather characteristic appearance.

Sutton & Beaumont, 1989: Now increasing slightly again in the County, this species was one of the many that became quite rare in the middle of the present century. Most records are from reasonably well-wooded areas near moorland. Several records are shown for the north side of Upper Teesdale by Dunn and Parrack (1986), but it has not been recorded in this area of VC65.
