lower surface blotch. The leaves finally are completely eaten out
and turn whitish. Pupation within the mine; the pupariumprium mostly
is located in the leaf tip (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 Griffiths (1976a), who points out that
the earlier description by Hering (1954a) is erroneous (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).
