Oviposition takes place in an upper leaf and a short mine is formed
either in the leaf or stem, but the larva feeds primarily in the
stem. Pupating in the stem (Spencer,
1976: 487 (fig. 857), 488).
and narrow corridor in the leaves, bracts or even calyx, ending
in a thick vein. From there the larva descends as a borer. Infested
plants largely die off. Pupation and hibernation within 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.
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 described by de Meijere (1946).
Pale yellow, usually narrow and elongate, with posterior spiracles
in the form of an elliptical, slightly raised plates each with up
to 25 bulbs (Spencer, 1976:
