A very rare species in Belgium.
Native
The larva lives in a slender composite leaf case that can reach a length of up to 18 mm. The older parts of the case are rather smooth and pale while the youngest frontal part consists of a brown and more hairy leaf fragment. The case shows a strong resemblance to the thorn-shaped stalks of its food plant. The mouth angle is about 30°.

The larvae are full-grown between March and May
The adult moths are on the wing in June and July.
Cytisus scoparius is the only foodplant in Belgium.
