Anoplus roboris Suffrian, 1840
[Coleoptera : Curculionidae]

Anoplus roboris Suffrian, 1840.

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 (Bladmineeders 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 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).
