Northern deep-brown dart
|Northern deep-brown dart|
As the common name suggests, this species usually has very dark brown forewings, although paler grey forms exist. There is always a much darker central band, almost black in the darker forms. By contrast the hindwings are much paler, often almost pure white but usually with darker venation. The wingspan is 36–41 mm. It flies at night in August and September  and is attracted to light and sugar as well as various flowers.
