forming a greenish-black blotch mine (Spencer,
1976: 92), which quickly turns brown, frequently several larvae
feed together (Spencer, 1972b:
upper-surface blotch, on Poplars much larger than on Willows. At
first the colour is green, but this quickly turns into an opaque
brown. The larvae distinguish these mines from those of Leucoptera
sinuella and Zeugophora species. They are yellow,
and often live communal. They leave the mine before pupation; the
exit slit is in the upper epidermis (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.
Yellow. Anterior spiracles each with 8 bulbs, posterior spiracles
each with 3 bulbs (de Meijere,
1934). The larva is illustrated in Bladmineerders van Europa.
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).
Yellowish to reddish brown; posterior spiracles each with 3 bulbs
on a low protuberance (Spencer,
1976: 92). The puparium is illustrated in Bladmineerders van Europa.
