Aulagromyza similis (Brischke, 1880)
long, whitish linear-blotch mine, frequently associated with the
mid-rib (Spencer, 1976: 321
(fig. 583), 323).
long (up to 16 cm), upper-surface, whitish corridor. Often the corridor
crosses itself so repeatedly that a secondary blotch develops. Sometimes
a few small grains of frass in the initial part of the mine. Otherwise
the mine is either completely free from frass, or a few big lumps
are deposited at the very end of the corridor. Pupation outside
the mine (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 larvae lie on their sides within the mine and use their pick-like mouthparts to feed on plant tissue.
Posterior spiraclesd with c. 30 bulbs (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).
Reddish; posterior spiracles on large conical projections, each
with up to 24 irregular bulbs extending upwards (Spencer,
1976: 323). The puparium is illustrated in the Encyclopedia
