Cerodontha unisetiorbita Zlobin, 1992.

Leaf-miner: Broad, uppersurface blotch (Bladmineerders van Europa).

The mines are pale-green intially, but turn brown with ageing. They are uppersurface and broad. A large leaf may contain several mines, which may merge. Pupation is in the mine (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.

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).

See Černý & Roháček (2015a) (Bladmineerders van Europa).
