Leaf-mine: A short irregular linear mine with frass in more or less connected threads (Spencer, 1976: 238).

Fairly long, upper-surface, little branched corridor; loops close together. Frass in pearl chains or strings. Pupation outside 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.

The larva is described by de Meijere (1937: 199, as Liriomyza sp. on Centaurea jacea); posterior spiracles each with 8-10 bulbs (Spencer, 1976: 238).

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).

Yellow (Paklaniskis, 1994a).
