unknown (Bladmineerders van Europa). Pupation internal (Spencer, 1972b: 104, as deschampsiae).
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 Nowakowski (1973,
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 Nowakowski (1973,
as deschampsiae). Brown, with distinctive posterior spiracles
(Spencer, 1972b: 103 (fig.
352), 104, as deschampsiae).
Puparium slender, light brown; rear spiracula strikingly elongated, on a broad base; also the (3?) bulbs elongated; anus on a characteristic tumescence (Bladmineerders van Europa).
