Leaf-mine: The frass is brown and in arcs, with narrow clear margins (unlike Stigmella continuella where the green frass completely fills the gallery) (British leafminers).

Oviposition on the underside of the leaf. Then a rather slender gallery, hardly widening, even towards the end. The corridor is not strongly contorted, not even in its first section; no browned spot in the leaf at the start of the mine. Sides of the corridor irregularly scalloped. The corridor mostly begins close to the leaf margin, often near the tip of the leaf. The coiled frass is brown or black, even in fresh mines; the frass fills most of the width of the corridor, but always leaves a transparent zone at either side. Pupation external; exit slit in the upper epidermis (Bladmineerders van Europa).

Larva: The larva is yellow, brown head, and dark ventral spots (British leafminers).

Yellow; described by Gustafsson and van Nieukerken (1990a) (Bladmineerders van Europa).

Pupa: Details unknown.

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