Leaf-mine: A gallery which leads to blotch (no slit in lower epidermis so the frass accumulates in the blotch) (British leafminers).

Oviposition on the upperside of the leaf, next to a vein. The mine begins as a narrow corridor with a broad frass line, running along a vein. Generally the corridor runs along the midrib, or along a lateral vein. In the latter case the direction usually is towards the midrib. The corridor abruptly widens into a blotch, containing much frass, laying against the midrib. Pupation external (Bladmineerders van Europa).

The mione is also illustrated in the Encyclopedia of Life.

Larva: Greenish or yellowish white, head and pronotal plate reddish-brown. The head is dark brown (British leafminers).

Translucent white with a dark brown head; no ventral plates. See Gustafsson and van Nieukerken (1990a) for a description (Bladmineerders van Europa).

Pupa: Details unknown.

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