Wingspan 6 -7.5 mm.
A relatively local and uncommon species, distributed mainly in the coastal counties around the British Isles.
The larval foodplants are creeping willow (Salix repens) and sandhill creeping willow (Salix arenaria). The larva feeds in a blotch on the underside of the leaf, which contracts and causes the leaf to pucker strongly. The mine is quite large and can occupy most of a leaf.
Like many other Phyllonorycter species, the moth has two generations, flying in May and again in August.
