specialization in the world Agromyzidae (Diptera) : 354, 355,
feeding singly, forming a long, widening mine on the upper surface
of the leaf, which is generally limited to one side of the leaf.
Pupation external, puparium glued to the leaf near the end of the
mine (Spencer, 1976: 128).
corridor, generally beginning near the leaf margin or close to the
leaf tip. Most of the times the mine remains at one side of the
midrib. The mine is upper-surface, but has some full depth, translucent
spots here and there. Frass in rather regularly scattered grains.
Pupation outside the mine. According to Dempewolf (2004a) only the
male genitalia enable a reliable discrimination from A. abipennis
and A. graminicola (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 was decribed by Griffiths (1963)
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).
Varying from black to reddish; posterior spiracular processes distinctly
separated, each with 3 bulbs (Spencer, 1972b: 34 (fig. 97); Spencer,
Black or dark brown; not unfrequently stuck to the leaf (Bladmineerders van Europa).
