ID pointers: A smaller version of the Broad-bordered Yellow Underwing but can be confused with Langmaid’s Yellow Underwing. There is a greenish collar when freshly emerged this fades to brownish. The forewing ground colour is a purplish, bluish grey with a fairly prominent reddish-purple patch towards the wing tip. This patch usually has three tiny white spots running along the leading edge. Hindwing is unmarked and orange-yellow in colour with a broad black band. These features help to distinguish from Langmaid’s.
