490 Coleophora lutipennella
(Zeller, 1838)
Wingspan 10-12mm.The larvae of this species feed on oak (Quercus), forming a pear-shaped silken case, initially on the underside of a leaf, moving its case to an angle of twigs to over-winter.
The adult moths emerge in a single generation in July and August, and are attracted to light, often flying some distance from the host plant.
The moth is thought to be common in England, Wales and southern Scotland.
