An unmistakeable yellow moth with chestnut-brown markings on the tips and along the leading edge of the forewings. They also have a white crescent or dash near to the leading forewing edge.
They can frequently be seen on the wing just before dusk and they are regularly attracted to light. Some overwinter as part-grown larvae on the foodplant but others as pupae in cocoons on the plant, in debris below it or in a crack in a wall.
