The wingspan is about 13 mm.The posterior tibiae is smooth above. Forewings are pale whitish yellow, with some scattered minute black dots, variable in development ; sometimes spots of grey strigulae, especially in disc;sometimes a ferruginous black -spotted median longitudinal streak from base of costa to apex. Hindwings are dark grey.[2] The typical form of the adult is a pale yellowish white, but there are variations, ranging to the rufous form F. aurantiella. Adults are on wing from July to October and overwinter.[3]

The larvae feed on evergreen oak (Quercus ilex) and common oak (Quercus robur). They mine the leaves of their host plant. The mine starts as a narrow lower-surface epidermal gallery, that widens into an oval, eventually full depth blotch between two side veins. Older larvae live freely, at first in a folded leaf margin, later in a partly rolled leaf tip. They possibly prefer young leaves.[4]
