Status
Common in oak woodland throughout much of England, Wales and southern Scotland, adults often flying some distance from the host plant.
Larvae form a pear-shaped silken case, initially on the underside of a leaf, moving its case to an angle of twigs to over-winter.
Adult moths are virtually impossible to identify without recourse to dissection.
