Davey, P., 2009: A species found across the southern half of Britain, the larva feeding on traveller's-joy (Clematis vitalba). In Dorset, the moth is frequent, and is found in the same chalky, clematis-rich, habitat type as the Small Waved Umber1781 and the Fern1782. The flight time spans four months, and two brood cycles are suspected. The first cycle is a double brood with peaks in mid-June and mid-August. The second cycle is a single brood with a main peak in mid-July. The national norm is for a single brood between late June and early August.
