irregularly linear, long, towards end wide. Pupation external (Spencer, 1972b: 80).
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.
Similar to those of Ph. tussilaginis (Griffiths, 1972b); anterior spiracles with 14-18 bulbs, posterior spiracles with 22-36 (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 (Spencer, 1972b: 80).
