Leaf-mine: A small somewhat irregular, elongate blotch (Spencer, 1972b: 57; Spencer, 1976:
273 (fig. 491), 274).
upper-surfcace blotch with fairly little frass in loose 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 (1925).
Posterior spiracles each with an ellipse of 8-10 bulbs (Spencer, 1972b: 57; Spencer, 1976:
274). The larva is 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).
The puparium is illustrated in Bladmineerders van Europa.
Leontodon autumnalis is
treated as Scorzoneroides autumnalis (Autumn Hawkbit) by
