Leaf-mine: A relatively long irregular linear mine, normally commencing near
the apex of the leaf and for a while following the leaf margin (Spencer,
broad, upper-surface corridor, sometimes forming a secondary blotch.
Frass in pearl chains or strings. Pupation outside the mine; exit
slit in upper epidermis (Bladmineerders van Europa).
The initial mine is a corridor, which normally follows the leaf edge. It then expands to form a blotch (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 briefly described by de Meijere (1943) 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).
Yellow (Bladmineerders van Europa).
