The wingspan is about 42–50 mm. Meyrick describes it Antennae in male ciliated. Forewings fuscous, towards costa rosy-tinged an obscure blackish median dash from base ; sub-basal, first, and second lines slightly paler, obscurely darker-edged, distinct on costa ; orbicular and reniform partly outlined with black, sometimes connected by a blackish mark or touching, orbicular rather elongate ; subterminal line pale, anteriorly with somewhat darker suffusion. Hindwings fuscous-whitish, darker posteriorly. Larva ochreous-brown ; dorsal line somewhat paler ; subdorsal series of curved or sometimes nearly straight oblique yellowish marks, edged above with dark fuscous ; head grey, fuscous marked. Adults are on wing from July to August.[1]

The larvae feed on Artemisia, Cirsium, Rumex, and Taraxacum species.

The species is suspected to have disappeared from the United Kingdom as a resident species during the first decade of the 21st century.[2]
