Leaf-mine: The first instar larva forms a shallow winding linear mine on the underside of the leaf, later forming a broad upper surface mine (Spencer, 1976: 436); initially frass in a narrow central line which after the larva moves to the upperside of the leaf is in irregular black lumps (Bladmineerders van Europa). Pupation internal (Spencer, 1976: 436).

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.

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).

The puparium is described by de Meijere (1928 and 1938a). Yellowish; posterior spiracles each with 13-16 bulbs (Spencer, 1976: 436).
