Leaf-miner: Larvae
feed singly, forming an upper surface linear-blotch mine. Pupation
either internal or external, with the puparium loosely glued to
the leaf (Spencer, 1976:
91).
Oviposition
near the leaf margin, at some distance from the leaf tip. From there
develops an upper-surface corridor-blotch. At first the mine ascends
as a narrow corridor towards the leaf tip, then the direction turns
and the mine, steadily widening, descends in the direction of the
leaf base. Frass irregular, in rather coarse grains. Larva solitary.
Pupation mostly outside the mine; in that case the puparium often
sticks to the leaf (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 Sasakawa (1961),
Griffiths (1963b), Dempewolf
(2001 :52) and 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).
Reddish, brown or black, posterior spiracles each with 3 bulbs,
the two processes adjoining. The puparium is illustrated
in Bladmineerders van Europa.
Comments:
The species is known as a serious pest of wheat and barley in Japan
(Spencer, 1973a).
