Leaf-miner: The
young larva first feeds towards the apex of the leaf, later turning
and feeding downwards. Several larvae can occur together in a single
leaf. Pupation external (Spencer,
1976: 130).
Upper-surface,
greenish, gradually widening corridor, at first running towards
the leaf tip, then reverses. Through fusion of several mines the
final mine is often communal. Frass in backish green grains, often
washed out. Pupation outside the mine (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 de Meijere (1925),
Hering (1953), Darvas and Papp (1985)
and Darvas, Skuhravá and Andersen (2000).
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; posterior spiracles each with 3 bulbs (Spencer,
1976: 130). The puparium is illustrated in Bladmineerders van Europa.
Comments:
A potentially serious pest on cereals.
