The wingspan is 11–15 mm.The forewings are shining bronzy, sometimes coppery-tinged ; six obscure golden metallic transverse streaks from costa between 1/3 and apex, and one or two from dorsum posteriorly, all sometimes obsolete ; a violet -black mark on tornus, enclosing two or three golden metallic dots, and a similar dot above it ; sometimes two or three fine black dashes above this ; a blackish apical spot ; dark line of cilia indented below apex. Hindwings are dark fuscous. Adults are on wing from May to August. The larvae probably feed on Juncus species.
