771 Carpatolechia alburnella
(Zeller, 1839)Wingspan c.13 mm.
From June to August, the adults of this species may be found resting in crevices on the trunks of the host trees, where their coloration makes for very effective camouflage.
The foodplant is birch (Betula), the larvae living between spun or folded leaves, and feeding within.
The species is well distributed in England and Wales, except the south-west, and also occurs in the Scottish Highlands, where the population has a rather darker colouration.
