Leaf-miner: Full depth blotch, invariably beginning at the leaf tip or the tip
of a leaf lobe or tooth. Oviposition site covered by a black, shining
drop of hardened secretion. Frass generally in long threads, but
sometimes in elongated granules (Bladmineerders van Europa).
The mine is also ullustrated in British Leafminers.
Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).
Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).
Pupation in the mine, not in a cocoon Bladmineerders van Europa.
The adult is illustrated in the Encyclopedia
of Life and British Leafminers.
