Theheart and club(Agrotis clavis) is amothof the familyNoctuidae.It is distributed throughout thePalearctic realm.
The common name of this species refers to the supposed shapes of the bold darkstigmataon the usually pale forewings. In this species all the stigmata have a rounded shape, contrasting with the elongated claviform stigmata of the much commonerheart and dart.The hindwings are grey, usually much darker than in heart and dart andturnip moth.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]Thewingspanis 35–40 mm. The main habitat iscalcareous grassland. The moth flies at night in June and July[1]and is attracted to light and sugar.
Thelarva,which is, when adult, dark brown with a pattern of black dots feeds on a variety ofherbaceousplants (see list below). The young larva feeds on the leaves of the food plant, later feeding on the roots. It overwinters as a full-grown larva in a cavity in the soil beforepupatingin the spring.
- ^The flight season refers to theBritish Isles.This may vary in other parts of the range depending on the weather.
