This is a rare species in Belgium, hitherto only mentioned from the provinces West-Vlaanderen, Antwerpen and Brabant.

The larva feeds on Acer pseudoplatanus, Acer platanoides and Acer saccharinum. When young in a small mine, usually near midrib in the angle between veins, later in 3 successive downwards cones made from the tip of a leaf lobe on the same or another leaf. Pupation under a yellow membrane on the underside of the leaf.

The adults hibernate. They fly from July till May.

ID: similar to other Caloptilia species, but usually recognised by its smaller size and the clear whitish band on the brown forelegs.
