Status and Distribution
A scarce and very local species. Rarely encountered as an adult, it has been recorded in southern and northern Wales, north west England, one location in the Western Isles of Scotland and a few scattered sites in Ireland. Since 1970 there have been only fourteen records from seven localities in the British Isles and since 2000 this has further reduced to only four sites (two in Wales, one in Ireland and one in England).

Foodplant and Larval Feeding Signs
Salix repens (creeping willow) - see distribution map, and in Ireland on Salix herbacea (dwarf willow). In Europe also reported to use Salix aurita (eared willow) and Salix caprea (goat willow).
Spins a few terminal leaves (c.5cm) together to form a tube around the twig.
Finding the Moth
Larva: the spun terminal leaves can be readily located but often produce Anacampsis populella which feeds in a similar fashion.
Adult: has been swept and disturbed from amongst the foodplant during the day
The small size, blackish-brown forewings with a purplish sheen when fresh, and the darker fascia at three quarters (best observed by varying the angle of the moth to light) are definitive for this species.
Single brooded from mid-June to mid-August.
Insufficient data to include early and late dates, with most records of bred specimens.
