The heart and club (Agrotis clavis) is a moth of the family Noctuidae. It is distributed throughout the Palearctic ecozone. The common name of this species refers to the supposed shapes of the bold dark stigmata on the usually pale forewings. In this species all the stigmata have a rounded shape, contrasting with the elongated claviform stigmata of the much commoner heart and dart. The hindwings are grey, usually much darker than in heart and dart and turnip moth. The wingspan is 35–40 mm. The moth flies at night in June and July and is attracted to light and sugar.
