Leaf-mine: A large blotch, larva frequently entering a second leaf to complete development (Spencer, 1972b: 35).

Single larva. Primary and secondary feeding lines indistinct. Frass in short thread fragments. Pupation outside the mine; exit slit upper-surface (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 Nowakowski (1964).

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).

Comments: Possibly a junior synonym of Agromyza canadensis Malloch, 1913.
