Yorkshire Status: Fairly common resident.

"Common probably everywhere" wrote Porritt in 1907. Since then, the ravages of Dutch elm disease have affected its numbers to a certain degree, but larvae can feed on various other broad-leaved trees and it remains fairly common in the county, not just in areas with wych elm. Numbers may have reduced a little in recent years, though it can still be caught in double figures at times, the maximum being 31 at Cornelian Bay (Scarborough) on 31/10/2020. It is easy to mistake worn specimens for the commoner Yellow-line Quaker.

Sutton & Beaumont, 1989: Recorded rather sparsely from all five vice-counties, occasionally locally common in the south. As suggested by Lorimer (MBGBI 10) and Skinner (1984) the larvae are most frequently found on wych elm. However they are reported to also feed on sallow in the east of the County (PQW pers. comm.), a foodplant not noted as usual elsewhere.
