The heart and club (Agrotis clavis) is a moth of the family Noctuidae.

The common name of this species refers to the supposed shapes of the bold dark stigmata on the usually pale forewings.

The differences are not consistent however; they are highly variable in both colour and markings, and identification of atypical or worn examples may prove impossible without examination of genitalia.See Townsend et al.[1] The wingspan is 35–40 mm.

The moth flies at night in June and July [1] and is attracted to light and sugar.

The larva, which is, when adult, dark brown with a pattern of black dots feeds on a variety of herbaceous plants (see list below).
