The hindwings of the Heart & Club (Agrotis clavis) are grey, usually much darker than in the Heart & Dart (Agrotis exclamationis) and the Turnip Moth (Agrotis segetum).
The wingspan is 35–40 mm.
The moth flies at night in June and July and is attracted to light and sugar.
Caught in my self made moth trap.
