Leaf-mine: Oviposition in the underside of the midrib or a thick lateral vein; the oviposition site develops into a large scar. The larva makes a corridor that runs towards the leaf margin. The ultimate part of the mine is a corridor in the leaf tip, with frass in a narrow black central line (Bladmineerders van Europa).

The mine starts by the midrib abd runs towards the leaf edge. The frass is in a narrow central line. The leaf may tear along the course of the mine (British leafminers).
