forms a linear mine, normally at the apex of leaf, winding backwards
and forwards and thus forming a secondary blotch which quickly turns
brown. Pupation internal (Spencer,
compact secondary blotch, without islands of unmined green tissue.
Mines usually dirty brown in colour, strikingly resembling a dead
and rotting leaf segment. Both primary and secondary feeding lines
apparent. Frass partly in long strings. Pupation takes place within
the leaf, in a lower-surface pupariuml chamber, often somewhat removed
from the mine itself (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 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).
The puparium is illustrated in Bladmineerders van Europa. Varies in colour from white to brown (Spencer,
