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.
The larva is described by Dempewolf (2001:
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).
Hosts in Great Britain & Ireland: Currently unknown.
There is a record of Aulagromyza
discrepans on Artemisia (Robbins, 1991), but as the
mine has not previously been described, the record needs confirmation.
elsewhere: Currently unknown. Not in Spencer (1990).
