A spring-flying species, the adults of this moth are on the wing in April and May.
It can be found in woodland, grassy areas, chalk downland and scrubland.
It is fairly well distributed and reasonably common over most of Britain.
A number of variations or aberrations occur, including a striking form ab. porrittii, found in Yorkshire, but scarce elsewhere.
The larvae feed on bedstraw (Galium).
