The wingspan is about 10 mm. The forewings are whitish yellow, but darker on the costal and apical parts than below the fold and irregularly sprinkled with small indistinct brownish transverse streaks. On the middle of the dorsal edge is a poorly defined brown transverse marking, crossing the light dorsal part and reaching beyond the fold. The hindwings are light ochreous grey.[1]
