Leaf-miner: Mine linear and winding in upper surface. Pupation in the mine (Spencer, 1972b: 88).

Upper-surface corridor, loops closely together. Frass in thread fragments or pearl string, seemingly lying in a central line. Pupation within the mine (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).

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).

White, grey or shining black (Spencer, 1972b: 88).
