Leaf-miner: Details
unknown.
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).
Shining brown, deeply segmented; posterior spiracles separated,
on short stalks, each with 3 bulbs, arising from a stout conical
protuberance (Spencer, 1976).
