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).
The adult is illustrated in the Encyclopedia
The species has been recorded feeding on decaying vegetation,
particularly giant hogweed, Heracleum
mantegazzianum and Cirsium. Chandler (1978) did not
indicate whether his host record was British or Foreign and is therefore
included under 'Hosts in Britain' and 'Hosts elsewhere'.
(1991) recorded Scaptomyza pallida on Polygonatum.
This is not correct (Willem Ellis, pers. comm.).
