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).
Irwin and Chandler in Chandler
(1978) did not indicate whether their host records were British
or Foreign and are therefore tentatively included under 'Hosts in
Britain' and 'Hosts elsewhere'.
