Leaf-miner: The young larvae make very small (≤ 3 mm) corridor or blotch mines, usually several in a leaf. The primary mine generally lies adjacent to the midrib; as far as I have seen the egg always is upper-surface. The secondary mines often are found in leaves without primary miner: obviously the larvae easily move to another leaf. The secondary mines are made from the underside of the leaf; while moving around silk is deposited under the leaf. Most frass is ejected from the mines, and part of the frass grains remain stuck in the spinning. Rather soon the larvae start living completely free in a common spinning under a leaf. They hibernate in a hibernaculum and continue living free in the spring (Bladmineerders van Europa).

Larva: Social; head black, with brown and white lines; body mottled reddish brown to fuscus grey (Agassiz, 1996a) (Bladmineerders van Europa).

Pupa: Illustrated by Patočka (1997a). (Bladmineerders van Europa).

Adult: The adult is illustrated in UKMoths. The species is included in mothdissection.co.uk.
