Wingspan 10 to12mm. This species is reddish brown in colour.
Most common near to well wooded areas containing oak, but may be encountered almost anywhere.
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 larvae of this species feed on oak forming a pear shaped silken case, initially on the underside of a leaf, moving its case to an angle of twigs to overwinter.
The moth is thought to be common in England, Wales and southern Scotland. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as common.
It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
