Leaf-mine: A long, winding leaf-mine on the upper surface of the leaf, with frass widely-spaced in conspicuous black lumps. Pupation internal, at the end of mine (Spencer, 1972b: 28 (fig. 68), 29).

Mines on Sonchus and Taraxacum are illustrated in British leafminers and on Solidago in 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 Sasakawa (1961).

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).

Black or whitish-grey; posterior spiracles asymmetrical, each have two distinct arms, with 4 bulbs on one arm and 7 bulbs on the other (Spencer, 1972b: 29).
