Leaf-miner: A narrow linear mine, with frass in black strips (Spencer, 1972b: 57; Spencer, 1976:
274). Narrow upper-surface corridor.
The
corridor often follows nerves, causing it to branch now and then.
Frass in strings. Pupation outside 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 (1925).
Posterior spiracles each with an ellipse of 8-10 bulbs (Spencer, 1972b: 57; Spencer, 1976:
274).
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-black (Spencer, 1976:
274).
