A species rarely observed in Belgium, mainly in azalea nurseries and parks with Rhododendron. It has his stronghold in the province of Antwerpen.

The young larvae make a gallery in the lower epidermis of a leaf of Rhododendron simsii, R. indicum etc. This gallery leads to a blotch contorting the leaf. Later, the larva constructs a cone by rolling a leaf downwards from the tip. Pupation under a white membrane on the underside of a leaf.

The adults fly in two generations a year: in May and in July-August. In mild seasons there is a small third generation during September-October. They come to light.
