Leaf-miner: A
long narrow greenish/yellowish mine. Pupation in leaf at end of
mine (Spencer, 1976: 220).
Long
upper-surface corridor, mainly in the top half of the blade. The
mine descends, but changes direction a few times (up, down, up).
Frass in one big lump. Puparium in the mine, fastened ventrally
in the mine with dried frass (Bladmineerders van Europa).
The mine is a long gallery which is formed mostly in the apical parts of the leaf (British
leafminers).
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 larvae lie on their sides within the mine and use their pick-like mouthparts to feed on plant tissue.
The larva is described by de Meijere (1938,
as sönderupi), Beri (1971a)
and Nowakowski (1973).
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).
Can be yellowish but is more normally dark brown; posterior spiracles
are on a low projection directed dorsally above the anus each with
one long curving bulb and two smaller ones folded around its base
(Spencer, 1976: 220-1, fig.
380).
Comments:
Carex ovalis is treated
as Carex leporina (Oval
Sedge) by Stace (2010).
