Rather long corridor winding through the leaf, regularly crossing
itself. The corridor later widenes considerably. Frass normally
in a narrow central line, but may also lie along the side, or be
absent. The larva regularly leaves a mine and restarts elsewhere
(Bladmineerders van Europa).
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).
