Leaf-miner: Upper-surface
corridor, descending towards the leaf base, generally following
the midrib. Frass in a double row of granules. Pupation outside
the mine (Robbins, 1991),
see also 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.
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).
