Leaf-miner: Blotch mine. Broad corridor, widening into a large transparant blotch with 1 or several, proportionally very large larvae that quickly completely mine out a leaf, then move to another leaf. At the start of the first mine at the leaf underside 1 or more oval egg shells. Pupation outside the mine (Bladmineerders van Europa).

Forms large blotches on leaves (British leafminers).

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 illustrated in Bladmineerders van Europa.

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).

Comments: Ackland in Chandler (1978) did not indicate whether his host records were British or Foreign and are therefore tentatively included under 'Hosts in Britain' and 'Hosts elsewhere'.
