in the leaf lower surface. After a short initial corridor of a few
mm length the larva makes an upper-surface corridor that mostly
begins with a dense knot in the leaf tip. Frass in long pearl chains
along the sides. In fresh material primary feeding lines are apparent.
Pupation outside the mine; exit slit in the lower epidermis. The
mine often causes the leaf to be malformed and wrinkled. Feeding
punctures in the lower surface (Bladmineerders van Europa).
The larva forms a long narrow upper surface mine. Most mines start close to the leaf tip. The larva exits through a slit. Pupation is external (British
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 (1926). The larva is illustrated in (Bladmineerders van Europa).
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).
Pale brown; posterior spiracles each with an ellipse of 10 bulbs
(Spencer, 1976: 525). The puparium is illustrated in (Bladmineerders van Europa).
