Leaf-miner: A
narrow linear mine adjoining the leaf margin in the first instar,
which later develops into an irregular blotch with conspicuous lumps
of greenish frass (Spencer, 1976:
302).
The
first instar larva makes a narrow upper-surface corridor along the
leaf margin. After it has moulted it begins a large upper-surface
blotch. Frass in conspicuous green lumps, that can run out irregularly.
Pupation outside the mine (Bladmineerders van Europa).
Forms
a narrow linear mine by the margin of the leaf which later develops
into a blotch. The blotch has clumps of greenish frass (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 larva is described by de Meijere (1925)
and Dempewolf (2001: 132);
posterior spiracles with 3 bulbs.
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: 302).
