Formerly Apamea finitima was considered a separate species and has also been classifies as a subspecies of Apamea basilinea, which is now also a synonym of Apamea sordens.

This species has a wingspan of 36–42 mm. The forewings are brown with mostly indistinct markings except for a narrow but distinctive black mark at the very base of the wing which gives the species its common name. The hindwings are greyish brown, darker towards the margin, with prominently dark venation. This moth flies at night in May and June [1] and is attracted to light and sugar.

The larva feeds on various grasses, including cereals (see list below). This species overwinters as a larva, feeding in mild weather throughout the season.

  1. ^ The flight season refers to the British Isles. This may vary in other parts of the range.
