Leaf-mine: Larva mining initially on lower surface of leaf, later filling the tip of the leaf on the upper surface with a linear blotch mine (Spencer, 1972: 77). The mine starts with a lower-surface, relatively wide corridor. After its first moult the larva continues upper-surface, its mine in the end entirely occupying several leaf segmets (Allen, 1956a; Hering, 1957). Frass in rather coarse granules. Pupation outside the mine, exit slit in upper epidermis (Bladmineerders van Europa). Larva: The larva are described Allen (1957b). Puparium: Black; posterior spiracles each with 20 bulbs (Spencer, 1972: 77).
