The lesser broad-bordered yellow underwing or Langmaid's yellow underwing (Noctua janthina) is a moth of the family Noctuidae. It is distributed throughout southern and central Europe, and southern Sweden. Like other members of its genus this species has bright orange-yellow hindwings but as the common name suggests the black sub-terminal bands are very broad and account for about half the area of the hindwings.

Noctua es un género de lepidópteros. Las alas anteriores son de colores opacos, crípticos y a menudo las posteriores tienen diseños brillantes que permanecen ocultos durante el reposo. Son buenos voladores.
