Leaf-mine: The eggs of this species are laid on a leaf, with the larvae mining the underside of the leaf, until a late instar when it feeds in a web under the midrib of the leaf, causing visible blotching on the upperside (UKMoths).

Short, full depth corridor. The larva relatively long lives as a miner, but finally leaves the mine and continues living in spinning along the midrib at the leaf underside, from where windows are eaten in the leaf (Bladmineerders van Europa).

Larva: Larva with black head and prothoracic shield. Body, thoracic feet and anal shield apple green; pinacula grey (Bladmineerders van Europa).

The larva is also illustrated in UKMoths.

Pupa: The larva pupates in August, usually amongst the leaf litter, occasionally within the web. The pupa is illustrated in UKMoths.

Adult: The adult is illustrated in UKMoths. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.

Time of year - larvae: July until early August (Bladmineerders van Europa).

Time of year - adults: The adults emerge in a single generation in September and hibernate through the winter, re-emerging in spring (UKMoths).
