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).
It is now believed that Phytoliriomyza pilosella, described
from Florida, may represent Phytoliriomyza scotica, but more
detailed study will be necessary before this possible synonymy can
be formally established (Spencer,
