Leaf-miner: Oviposition in the base of the midrib, without giving rise to an oviposition scar. The larva initially bores inside the midrib. Later it leaves the midrib, forming a broad corridor in the blade, that widens into a blotch. Finally the legless larva pupates in a globular cocoon inside the mine. Because the mine develops at a time that the leaf is fully developed, mined leaves are not disfigured (Bladmineerders van Europa).

Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs.

Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).
