small regular blotch, which can be enlarged when several larvae
feed together (Spencer, 1972b:

upper-surface blotch, about 1 cm in diameter. No trace of a preceding
corridor. Frass in coarse grains. Pupation outside the mine; exit
slit in upper epidermis (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 (1926);
anterior spiracles each with 6 bulbs (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).
Black; posterior spiracles each with an ellipse of 14 bulbs (Spencer,
