Leaf-mine: A shallow whitish linear-blotch mine (Spencer, 1976: 164-5, fig. 300).

Upper-surface blotch, preceded by a very short corridor. Often several larvae in a mine. Frass in isolated grains. Pupation outside the mine; exit slit in upper epidermis (Bladmineerders van Europa).

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 (1937) and Sasakwa (1961) 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).

Yellowish-brown; posterior spiracles each with 3 bulbs (Spencer, 1976: 164).
