Leaf-miner: The mine begins in the midrib, especially in a lower leaf, extending
into the leaf disc, branching irregularly or pinnately, may also
locally be blotch like. The mine is brown and very transparent.
Sides very irregularly eaten out. Frass loosely dispersed or in
a loose central line, buy may also be pressed against the sides
of the corridor. The larva may also leave the mine and restart elsewhere
(Bladmineerders van Europa).
Forms an irregular branched corridor mine associated with the midrib or from the petiole. The larvae changes leaves and the mine develops into a blotch in the second leaf (British
Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).
The larva is illustrated in British
leafminers and Bladmineerders van Europa.
Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).
Leontodon autumnalis is treated as Scorzoneroides autumnalis (Autumn Hawkbit)
by Stace (2010).
