The Rustic Shoulder-knot (Apamea sordens) is a moth of the family Noctuidae. It is distributed throughout Europe, Asia, and North America.

Habitat in Siberia

This moth has a wingspan of 36 to 42 mm. The forewings are brown with mostly indistinct markings except for the narrow black mark at the base of the wing which gives the species its common name. The hindwings are greyish brown, darker towards the margins, with prominent dark venation. This moth flies at night and is attracted to light and sugar. Its flight season in the British Isles is May and June.

The larva feeds on various grasses, including oats, fescues, barleys, canarygrasses, timothy, ryes, wheats, and wild rice.[1] This species overwinters as a larva, feeding in mild weather throughout the season.

Its habitat includes fields, grasslands, and steppe.
