DIPTERA LARVAE
(examples, not to scale)

Larva : Coleoptera : Diptera : Hymenoptera : Lepidoptera
Pupa/Puparium : Coleoptera : Diptera : Hymenoptera : Lepidoptera
Diptera : Anterior spiracles : Posterior spiracles : Cephalo-pharyngeal skeleton

The larvae of flies are leg-less maggots without a head capsule. They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton, usually visible internally through the body wall. The larvae lie on their sides within the mine and use their pick-like mouthparts to feed on plant tissue. In some corridor miners frass may lie in two rows on alternate sides of the mine. In order to vacate the mine the fully grown larva cuts an exit slit, which is usually semi-circular (see Liriomyza huidobrensis video).

The identification of this larva has not be confirmed by breeding;
it therefore can just as well be A. nigrella
