upper-surface corridor usually containing several larvae that graze
shoulder to shoulder from the leaf tip downwards. Pupation outside
the mine. Mines and larvae are indistinguishable from those of A.
nigrella (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.
Larval mandibles with two teeth; posterior spiracles far apart (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).
The puparium is illustrated in Bladmineerders van Europa.
