The setaceous Hebrew character (Xestia c-nigrum) is a moth of the family Noctuidae.

The forewings of this species are reddish brown with distinctive patterning towards the base: a black mark resembling the Hebrew letter nun (נ), thus inspiring the common name, with a pale cream-coloured area adjacent to this mark.

"Setaceous", meaning "having bristles", refers to the hairs on the top of the thorax and fringing the wings.

Forewing purplish grey or purplish fuscous with a leaden gloss; costal area at middle ochreous, merged with the bluntly triangular orbicular stigma: cell, a submedian basal blotch, and costal spot before apex purplish black; claviform stigma minute; reniform large, the lower lobe purplish; hindwing ochreous whitish, in female with the termen broadly fuscous.

[1] This moth flies at night and is attracted to light and sugar, as well as flowers such as Buddleia, ivy and ragwort.
