The wingspan is 16–18 mm. The forewings are yellowish orange with fuscous-purple markings. There is a small spot on the base of the costa and five narrow transverse fasciae, the first at one-sixth, rather inwardly oblique, the second at one-third, rather outwardly oblique, the third median, oblique, irregularly angulated or dilated, the fourth at three-fourths, irregular, the fifth terminal, meeting the fourth at the tornus. There is also a small discal spot beyond the third, sometimes connected with it. The hindwings are whitish ochreous in males, with the posterior third suffused with dark fuscous, with a deep groove along the fold containing a very long expansible whitish-ochreous hair-pencil. The hindwings of the females are grey.
