shallow, irregularly linear mine which can develop into a secondary
blotch (Spencer, 1972b: 90).
Pupation internal, the puparium loose in the mine (Spencer,
whitish (shallow), strongly contorted corridor, that may form a
secondary blotch. Frass in a few, widely scattered grains. Pupation
mostly within the mine; in front of the brown puparium lies a preformed
exit slit (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 (1926)
and Griffiths (1976c).
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).
Brown (Spencer, 1976: 494). The puparium is illustrated in (Bladmineerders van Europa).
