Leaf-mine: A secondary blotch near the apex of a leaf segment which develops from short, adjoining sections of a linear mine. Pupation takes place in the mine (Spencer, 1976: 482).

A compact secondary blotch, without islets of unmined tissue. Mine without brown discoloration. Both primary and secondary feeding lines recognisable. Pupation within the leaf, in a lower-surface section of 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 larva is described by de Meijere (1950) and Hering (1954) (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).

Yellow; posterior spiracles each with 12 well-defined bulbs, froming an almost complete circle (Spencer, 1976: 482).

Hosts in Great Britain and Ireland: Currently unknown.
