Leaf-miner: The
mine mine begins as a long, hairlike corridor. The last part of
it runs perpendicular to a leaf segment. The part of the leaf that
thereby is cut off Wiltshire, and here a large blotch is made. Frass
scattered in the mine. Mine practically full-depth, yellowish green
to reddish brown, with conspicuous secondary feeding lines. Pupation
outside the mine. See also Seidel (1926a) for an extensive description
of 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 Seidel (1926).
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).
Yellow; anterior spiracle openings arranged in large arcs, not elevated
on a fan-shaped structure; posterior spiracles each with the central
opening larger and more raised than the lateral openings (White,
1988).
