Phytomyza rapunculi Hendel, 1927a; Spencer, 1990. Host
specialization in the World Agromyzidae (Diptera) : 231, 232
(figs 874-5), 400.
Very long, rather deep corridor, initially lower-surface, later
upper-surface. In smaller leaves almost always a secondary blotch
originates, that can occupy the entire leaf. Frass initially in
pearl strings, later in scattered aggregations. 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.
Yellowish. Mandibles with 2 teeth, alternating. Both anterior and
posterior spiracles two-horned, with 12-19 and 18-24 bulbs, respectively
(Beiger, 1972a; Spencer, 1971a).
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, smooth, without intersegmental depressions.
