Leaf-miner: Larval
leaf-mine starts as a narrow channel running towards apex of leaf
but later develops into a broad blotch running downwards. Frass
largely diffused, giving the mine a characteristic greenish appearance.
Pupation external (Spencer, 1976:
126).
Corridor,
usually several in one leaf, running from close to the leaf base
up to near the tip, then reversing direction and widening, resulting
in one communal mine in which the larvae descend in a common front
. Frass somewhat deliquescent, mine therefore strikingly green.
Pupation outside the mine. Neither mine nor larva distinguishable
from those of mobilis (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),
Spencer (1966c: 288) and
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).
Iillustrated by d'Aguilar, Chambon and Touber (1976a) (Bladmineerders van Europa).
Comments:
A potentially serious pest of wheat.
