Aulagromyza luteoscutellata (de Meijere, 1924)

Leaf-mine: Mines similar to A. hendeliana but darker (British leafminers), filled centrally with dark-green frass (Spencer, 1976: 318).

Little widening, upper-surface corridor, generally unbranched and not associated with the leaf margin. Frass in a broad green band with scattered dark granules, sometimes locally with ill-defined strikes. Pupation outside the mine; exit slit in 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.

The yellow larva is illustrated in Bladmineerders van Europa and British leafminers.

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).

Posterior spiracles on short projections, each with an ellipse of 12 sligtly chitinised bulbs (Spencer, 1976: 31).The puparium is illustrated in British leafminers.
