Wingspan 7 to 9 mm.
Areas where willow is present.
The species is bivoltine, with a flight period in late May and June and again in August.
The mines are found on the leaves of Willow (Salix) in July and then September to early November and are large and not regularly shaped. They can be confused with Phyllonorycter dubitella mines and the moths should be bred out to confirm identification.
Widespread and fairly frequent in 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).
