Leaf-miner: A rather stubby, gradually widening, corridor that usually begins
near the leaf tip and descends along the leaf margin (especially
in the first generation). Finally an almost perfectly circular excision
is cut, in which the larva drops to the ground for pupation (Bladmineerders van Europa).
A
broad gallery with scattered frass, usually along the edge of the
leaf, ending at a circular blotch from which a case is cut leaving
a round hole (British
leafminers).
Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).
The larva is a yellow colour, with distinctive anterior markings
(British
leafminers). Illustrated in Bladmineerders van Europa.
Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sujiformia/curculionoidea/curculionidae/curculioninae/rhamphinini/orchestes/orchestes-quercus/orchestes-quercus-larva/" target="_blank">Bladmineerders van Europa.
Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).
Pupation inside the mine, in a spherical cocoon (British
leafminers).
