Leaf-miner: Oviposition in the underside of the midrib or a thick lateral vein;
the oviposition site develops into a large scar. The larva makes
a corridor that runs towards the leaf margin. The ultimate part
of the mine is a corridor in the leaf tip, with frass in a narrow
black central line (Bladmineerders van Europa).
The mine starts by the midrib abd runs towards the leaf edge. The frass is in a narrow central line. The leaf may tear along the course of the mine (British
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).
