Description

The wingspan is 11–14 mm. Forewings are white, with golden or brown markings, while hind wings are grey. Legs and antennae are white. They fly in a single generation from May to August, depending on location.[1]

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.[2]

Recorded food plants include goat willow (Salix caprea) and grey willow (Salix cinerea)[3]

Habitat

In North America these moths mainly live in mountainous areas, but are also present in prairies with the host plants.[1]

Distribution

This species can be found in Europe, northern Asia and North America.[1].[2] [4]
