Species Account

Sutton & Beaumont, 1989: This species usually occurs on the south coast where it became established by immigration in the 1950s (Williams, 1958). The first northern record in Britain occurred in 1973 in Yorkshire, trapped by P.Q. Winter.

Beaumont, 2002:
VC61. Spurn, 1.8.1991, 29.7.1992 (BRS); Bridlington, 9.8.1996 (KAB); Rudston, 12.8.1996 (ASE).

Argus 58, 2009: There have been no records away from its stronghold at Spurn since 1996. The Spurn colony has grown to record levels this year so we may see some further expansion in range.
VC61. Spurn area, 39 records of 64 moths from 3.7-12.8.2009 (BRS, PCA, MJS).

Current status (CHF, 2011): A large increase at Spurn though the moth has disappeared from locations further up the coast.
