Leaf-mine: Larvae feeding in basal leaves, mainly in mid-rib, moving from one leaf to another via the base of the leaves. Pupation internal (Spencer, 1972b: 68).

Most of the time the larva lives in the midrib of the rosette leaves. Now and then short excursions are made into the blade. At first they are pale green, later they are almost full depth and whitish, and quite conspicuous. They do not contain frass. The larva may migrate from one leaf to another by way of the heart of the rosette. For its development it needs 3-4 leaves. Pupation within the mine. Before that the larva has scraped clean the wall of the pupariuml chamber up to the cuticula. (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).
