Leaf-mine: Larva initially forming an irregular linear mine, which later develops into a conspicuous blotch; frass conspicuous.

Initially an upper-surface, narrow corridor of about 3 cm, that abruptly widens into an ill-coloured secondary blotch, which generally incorporates more or less of the corridor. Secondary feeding lines usually conspicuous. Pupation outside the mine; exit slit in the lower epidermis (Bladmineerders van Europa).

Forms an iregular upper surface blotch with conspicuous black frass (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 Sasakawa (1961) and Dempewolf (2001: 147).

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).

Puparium orange (Bladmineerders van Europa). Posterior spiracles each with an ellipse of about 10 bulbs.
