The wingspan is 19–23 mm.The forewings are whitish ochreous,more or less suffused with fuscous and sprinkled with dark fuscous ; costa spotted with dark fuscous ; first discal stigma and a dot obliquely before and above it black ; second indistinct, dark fuscous ; a dark fuscous spot between and above these ; dark fuscous terminal dots. Hindwings are pale whitish-fuscous.The larva is green, paler laterally ; dorsal and subdorsal lines dark green ; dots blackish ; head light brownish-ochreous ; 2 with two blackish spots.[1]


The larvae feed on Arctium lappa, Carduus, Carlina, Centaurea jacea, Centaurea nigra, Centaurea scabiosa, Cirsium vulgare, Knautia, Serratula tinctoria and Sonchus. They mine the leaves of their host plant. The mine has the form of a short full depth corridor. The larva soon vacates the mine, creating a spinning at the leaf underside, from where it causes window feeding.[2] Larvae can be found from May to early August. They are pale green or yellowish with a pale brown or yellowish head.
