Leaf-mine: Larva forms an upper surface primary blotch with several larvae feeding together; the blotch is greenish when fresh but becomes yellowish with age (Spencer, 1972: 78 (fig. 257); Spencer, 1976: 376, 377 (fig. 655)). Round or oval blotch, green at first, later yellowish. Young mine are interparenchymatous, only the older mines are truly full depth. Generally several larvae in a communal mine. Pupation outside the mine. Exit slit in lower epidermis (Bladmineerders van Europa). A conspicuous, yellowish, almost circular upper surface blotch. Normally several mines on a leaf which may run together giving the impression of a single mine (British leafminers).

Larva: The larva is described by Allen (1956, 1957b), Griffiths (1973c), de Meijere (1926) and illustrated in Bladmineerders van Europa; posterior spiracles with approx. 20 bulbs.

Puparium: Black; each side of the anus has a distinct conical projection; posterior spiracles each having an ellipse of some 20 minute bulbs or bulbs (Spencer, 1976: 376). Illustrated in Bladmineerders van Europa.
