association with the leaf venation. Frass in a diffuse, central,
green band. After a shower or two most of the frass is washed out
and the mines appear white. Pupation outside 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 bright yellow larva is described by de Meijere (1925)
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).
Reddish-brown; posterior spiracles each with 3 bulbs on short conical
projections (Spencer, 1976:
