Agromyza bromi Spencer, 1966c; Spencer, 1990. Host specialization
in the world Agromyzidae (Diptera) : 355, 358 (figs 1337-8),
of mine and larva unknown. Because the adult fly closely resembles
that of A. nigrella, possibly
this applies as well to mine and larvae (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.
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 widely separated, each with 3 bulbs.
(Spencer, 1976: 102).
Rear spiracula not on a common base, with 3 bulbs (Spencer, 1966a) (Bladmineerders van Europa).
