The wingspan is 3–5 mm. Head ferruginous - orange. Antennal eyecaps ochreous-whitish. Forewings deep shining golden-bronze ; a shining golden -silvery fascia beyond middle, edged anteriorly with purple suffusion, apical area beyond this deep purple ; an apical shining golden -silvery fascia, partly in cilia.

Adults are on wing from June to August and from September to November.
