Leaf-miner: A rather stubby, gradually widening, corridor that usually begins
near the leaf tip and descends along the leaf margin (especially
in the first generation). Finally an almost perfectly circular excision
is cut, in which the larva drops to the ground for pupation (Bladmineerders van Europa).
broad gallery with scattered frass, usually along the edge of the
leaf, ending at a circular blotch from which a case is cut leaving
a round hole (British
Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).
