linear mine, frequently on lower surface at beginning; frass with
closely adjoining grains.
often brownish, corridor, in the end often occupying the width of
a leaf segment. Older segments of the mine are much less conspicuous,
lower-surface and quite shallow. Where upper- and lower-surface
stretches overlap transparent patches occur, when the leaf is illuminated
from behind. Frass in isolated grains, sometimes locally pearl chains.
Pupation outside the mine (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 Hering (1967: 25). The
posterior spiracles have 13-17 bulbs. The posterior spiracles are 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).
Black; posterior spiracles each with 15 bulbs.
