Forewings shining golden whitish ; a dorsal spot at 1/3 connected with base by a streak along fold, an outwardly oblique streak from middle of dorsum, and a tornal spot shining golden.

Biology
Eggs are laid on willows and the larvae overwinter in leaf-buds until April when they bore into a shoot, causing it to droop. They can also feed on catkins. When full grown in May or June the larvae are 11 mm long with a green body and dark-brown to black head, prothoracic and anal shields. Pupation takes place either in the feeding place or on the ground in May or June.
Recorded food plants include goat willow (Salix caprea) and grey willow (Salix cinerea)
Habitat
In North America these moths mainly live in mountainous areas, but are also present in prairies with the host plants.
Distribution
This species can be found in Europe, northern Asia and North America.
