Leaf-miner: Larva forming an irregular upper surface linear mine, which can widen and become almost blotch like at end (Spencer, 1972b: 78 (fig. 262), 81; Spencer, 1976: 378, 379 (fig. 657)).

Upper-surface blotch, often following the leaf margin for some length, finally strongly widened. The real start of the mine, however, is a long narrow epidermal corridor in the lower surface of the leaf, made by the first instar larva (Allen, 1956a). Pupation outside the mine, exit slit generally in the leaf lower epidermis (Bladmineerders van Europa).

An upper surface mine, which can widen and form a blotch (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 Allen (1957b), Griffiths (1973c), de Meijere (1938) 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).

Black; posterior spiracles each with 22-28 bulbs or bulbs (Spencer, 1976: 378).
