The wingspan is 30–40 mm. The length of the forewings is 16–20 mm. The ground colour of the forewings varies from bright ochre to gray to brown, often with a reddish or light purple tint. Orbicular and reniform are not clearly marked. The hindwing is orange-yellow with a broad distal black band. This species can only be separated from Noctua janthina by examination of the genitalia.[1] The moth flies in one generation from late June to September.
The larvae feed on various deciduous trees, shrubs and herbaceous plants.[2]
Notes
- ^ The flight season refers to Belgium and The Netherlands. This may vary in other parts of the range.

gollark: In the scheme version, my "grudger who gives you 3 chances" works slightly better.]
gollark: Ah, right.
gollark: Basically. It's also x^n and not n^x.
gollark: I'm trying to tweak the parameters a bit in the scheme version.
