292 Caloptilia leucapennella
(Stephens, 1835)Wingspan c. 13mm.
A local species, distributed widely though thinly, over much of the British Isles, though less common in the south and east.
The typical form of the adult is a pale yellowish white, but there are variations, ranging to a rufous form, f. aurantiella, which can cause confusion with other related species.
The larval foodplant is oak (Quercus), the larva initially mining the leaf, then creating a fold at the edge, followed later by two or more 'cones' formed by rolling the leaf tip.
Adult moths are on the wing from July to October, when they overwinter in the manner of other Caloptilia species.
