of the Lepidoptera of Belgium

Caloptilia elongella (Linnaeus, 1761)

A common species throughout Belgium.

The larvae feed on Alnus glutinosa, when young, in an irregular epidermal mine on the upperside of a leaf, later rolling a leaf downwards longitudinally, in two such spinnings. Pupation in a silken membrane, usually on the underside of a leaf.

The adults fly in two generations a year: in June, and again from late August till April. They hibernate in evergreen trees. They come to light.
