Petiole-borer: Feeds and pupariumtes in the petiole (Spencer, 1990: 21).

Essentially a borer in the petiole, but now and then the larva may also make corridors in the leaf blade. Pupation in the petiole (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 (1943). Brownish-black; posterior spiracles greatly enlarged, on projections extending laterally, each with a double ellipse of numerous minute bulbs (Spencer, 1976: 499-500).

Hosts in Great Britain & Ireland: Currently unknown.
