A long narrow leaf-mine which winds round the filiform leaves and
can penetrate deeper into the parenchyma, becoming invisible. Pupation
internal (Spencer, 1976:
corridor, spiralling around the leaves. Often part of the corridor
in the deeper layers of the leaf. Frass in strings. Pupation generally
within the mine (Bladmineerders van Europa).
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).
Reddish; posterior spiracles each with 3 rather large
bulbs (Spencer, 1976: 230).
Both Liriomyza angulicornis and Liriomyza
latipalpis can occur in the same plant (Spencer,
