It is much more common in the southern part of the range. 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.
