Norellisoma spinimana (Fallén, 1819)
[Diptera: Scathophagidae]


Cordylura spinimana Fallén, 1819. Scaptomyzides Sveciae: 7
Norellisoma septentrionale Hendel, 1930. Ark. Zool. 21A (18): 2.
Norellisoma spinimana (Fallén, 1819).


Stem borer: 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).

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