Host specialization in the world Agromyzidae (Diptera)
: 354, 367, 368 (fig. 1376).
Lower-surface corridor in the top half the leaf blade; the mine
changes direction at least two times. One to three larvae in a mine.
Frass in rather regular granules (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 Nowakowski (1973). The description of the larva by de Meijere (1925a) is based on material from Phragmites, and therefore refers to C. phragmitidis (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).
The puparium is described by Nowakowski (1973).
Pupation mostly outside the mine (Bladmineerders van Europa).
