shallow, upper surface, whitish linear mine. Pupation external (Spencer, 1972b: 72 (fig. 233A), 77).
upper-surface corridor, often somewhat geryish, and/or following
the leaf margin. Frass grains fairly small, separated by about their
own diameter. Primary feeding lines often conspicuous. Pupation
outside the mine; exit slit in upper epidermis (Bladmineerders van Europa).
A long whitish upper surface mine. The frass grains are small and can occur close together (British
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 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 an ellipse of up to 26 minute
bulbs (Spencer, 1972b: 77).
