(Linnaeus, 1758)
Wingspan 28-32 mm.Reasonably common in southern and western parts of Britain, but elsewhere is rather local.
Occurring in suburban habitats, waste ground and woodland margins, it flies in June and July, sometimes with a second generation in the autumn.
The larvae feed mainly on nettle (Urtica dioica) in the autumn, and the species overwinters as a pupa.
