([Denis & Schiffermüller], 1775)
Wingspan c.18-20 mm.
A local species, distributed widely but scarcely throughout much of southern England and Wales, and extending northwards to Lancashire.
Preferring damper habitats such as river banks, bogs and water meadows, the adults fly mainly in July and August.
The larvae feed on white willow (Salix alba) and crack willow (S. fragilis), spinning two or more leaves together and feeding within.
