Leaf-mine: A shallow, greenish upper surface blotch-mine, which can be somewhat elongate but never obviously linear. Pupation external (Spencer, 1976: 321 (fig. 581), 322).

Irregular, yellowish green, upper-surface blotch. Pupation outside the mine; exit slit in upper epidermis. The exit slit is unusually long: from half to almost three quarters of a circle. Frass in rather few, coarse grains (Bladmineerders van Europa).

The mine is also illustrated in and British leafminers.

Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.

The larva is described by de Meijere (1934) and illustrated in Bladmineerders van Europa.

Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).

Dark brown; posterior spiracles each having two arms, with a total of some 20 bulbs (Spencer, 1976: 322).
