Leaf-miner: Generally small, upper-surface, pear-shaped mines, half of their
surface stuffed with frass. In the frass-free part an oval, flattened
larva. Often several mines in a leaf. Prior to oviposition the larvae
eat, a large number of tiny holes in the leaves (Bladmineerders van Europa).
The larva over winters in the upper surface mine. There can be several mines in a 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).
