In Dorset, the moth has been seen on two occasions: Corfe Castle, one in a trap for wasps in the walled peach garden at the rectory on 9 September 1892 (Reverend E Bankes), Portland, at MV light on 11 September 1993 (M Cade).

This species is similar to Red Underwing2452. Diagnostics include: smooth light grey ground colour; edge of wing has row of black dots not dashes; a deeply-troughed 'W' mark is present on the post-median line.
