Wingspan 8 to11 mm. The adult moth is golden brown and has darker tips to the forewings.
Found in deciduous woodland.
It flies in May and June.
The larva generally feeds on the leaves of oak or sweet chestnut forming distinctive white mines on the upperside. The larvae overwinter inside a circular chamber in the mine, and then pupate inside this chamber in late spring. The larval stages occur from September and October.
Fairly common in suitable habitat throughout much of Britain. 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).
