Sutton & Beaumont, 1989: First taken at Spurn (VC61) in 1948 (YNU, 1970). This species is still found frequently at this location and there are also now three additional localities.
VC61. Spurn, no change in status over past twenty years, numbers caught at light each year vary between two and twenty (BRS); Muston near Filey, one netted at dusk on the Carrs, 22.7.1979 (PQW, TAP), one in MV trap 25.7.1985 during a period when movement of many species seemed to be taking place, suggesting it may usually be present but static (PQW).
