Aulagromyza populicola (Haliday, 1853)
shallow, greenish upper surface blotch-mine, which can be somewhat
elongate but never obviously linear. Pupation external (Spencer,
1976: 321 (fig. 581), 322).
yellowish green, upper-surface blotch. Pupation outside the mine;
exit slit in upper epidermis. The exit slit is unusually long: from
half to almost three quarters of a circle. Frass in rather few,
coarse grains (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.
The larva is described by de Meijere (1934) and illustrated in Bladmineerders van Europa.
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).
Dark brown; posterior spiracles each having two arms, with a total
of some 20 bulbs (Spencer, 1976:
