Leaf-miner: Larvae
either singly or several in leaf, then forming large blotch-mine,
feeding first up and then down the leaf. Pupation external (Spencer,
1976: 119).
Shallow
upper-surface corridor, without full-depth sections, starting high
in the leaf. Initially the corridor runs up, but soon it changes
direction, quickly widening. In Deschampsia generally one
mine per leaf, occupying its entire width; in Glyceria there
mostly are serveral mines that merge in the end. Pupation outside
the mine; 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 Griffiths (1963)
and in Bladmineerders van Europa. Mandibles with three teeth (Spencer,
1976: 119).
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).
Black or dark red, frequently adhering to the leaf near end of mine;
posterior spiracles each with 3 bulbs (Spencer,
1976: 119).
Black or dark brown (Karl, 1926a) (Bladmineerders van Europa).
Comments:
Records on Elytrigia (as Agropyron), Bromus and Holcus given by Hering
(1957a) are considered doubtful by Griffiths (Spencer,
1990) and represent other Agromyza species.
