The male is smaller than the female with a less distinct central cross band. The male is similar to smaller forms of the Cloaked Minor but this species has a straight bottom edge to the central cross band which is less strongly bordered with white than in the Least Minor. The Irish form of this moth is redder and brighter than in England.
The males often fly in sunny weather from mid-day throughout the afternoon. They can also be disturbed from grassy vegetation when at rest. They also fly after dark. The caterpillars can be found from August to late the following May overwintering as small larvae in the sward. They pupate in flimsy cocoons on the ground.
