yet rather deep, therefore quite transparent, blotch, always along
the leaf margin, generally in the distal half of the leaf. The blotch
is preceded by a short and broad corridor, most of the time overrun
later. Four to eight larvae may co-occur in a leaf. Pupation outside
the mine, exit slit in lower epidermis (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 3 bulbs (Spencer,
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).
