Species Account

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.

2012 (CHF): Widespread across the county. Numbers vary a lot from year to year. There are few larval records though the largest numbers of adults are from elm-rich woodland.
