Leaf-mine: A short, broad, irregular linear mine, exclusively in the spongy parenchyma, on underside of leaf. Pupation external (Spencer, 1976: 323, 325 (fig. 585)).

Yellowish, 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 leafminers).

Larva: Anterior spiracles with up to 10, posterior spiracles with about 16 bulbs (Hering, 1955a).

Puparium: Yellowish; posterior spiracles each with a regular ellipse of some 20 minute bulbs (Spencer, 1976: 323).

Hosts elsewhere:

Time of year - mines: July-August.

Time of year - adults: April-May the following year.
