Leaf-miner: A large, full depth transparent light brown blotch that expands
irrespective of the leaf venation. Mine mostly in the distal half
of the leaf, may eventually occupy half of its surface. The mine
often tears in, and the leaf tip is disfigured (Bladmineerders van Europa).
Forms a blotch mine at a leaf tip and can distort the leaf. The mine may occupy half the leaf (British
Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).
The larva is illustrated in Bladmineerders van Europa.
Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).
The larva eventually pupates in a globular cocoon within the mine
(Bladmineerders van Europa).
