Scientific name: Standfussiana lucernea
June to September. Coastal Britain and Ireland, occasionally inland in Wales. A large, pale to dark grey moth found along coastal cliffs, mountain scree and other rocky, sparsely vegetated sites.
This moth can be variable in colour but its lack of distinct markings aids its identification. The Dotted Rustic is similar but has stronger markings with dots on the forewing, whilst the Stout Dart resembles darker forms but has kidney-shaped marks and black streaks on the forewings. The Grey is similarly pale but smaller without the white fringe on the hindwing.
Can be found flying energetically in the late afternoon on sunny days. Also flies after dark.
