Aulagromyza tremulae (Hering, 1957).
short, broad, irregular linear mine, exclusively in the spongy parenchyma,
on underside of leaf. Pupation external (Spencer,
1976: 323, 325 (fig. 585)).
lower-surface corridor with irregular sides. Frass in fine grains,
irregularly scattered. Pupation outside the mine, exit slit in lower
epidermis (Bladmineerders van Europa).
A long winding lower surface gallery. The mine of A.populi is similar, but the pupation is in the mine in this species. A.populi mines are partly, sometimes fully, upperside, whereas A.tremulae mines are lower surface (British
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.
Anterior spiracles with up to 10, posterior spiracles with about 16 bulbs (Hering, 1955a).
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).
Yellowish; posterior spiracles each with a regular ellipse of some
20 minute bulbs (Spencer, 1976:
