Leaf miner:
A somewhat inflated full depth blotch, that begins at the leaf margin. The oviposition causes the leaf to roll inwords, covering (and hiding) the mines. Often several mines in a leaf. Mainly in suckers (Bladmineerders van Europa).

Larva makes large blotch mines, which cause the leaves to curl over. Two mines are illustrated. The rolls brown as the mine ages (British leafminers).

Larva: The larvae of sawflies have a head capsule, chewing mouthparts with opposable mandibles, six thoracic legs and abdominal legs (although they may be reduced) (see examples).

The larva is illustrated in British leafminers.

Pupa: The pupae of sawflies have visible head appendages, wings and legs which lie in sheaths.

Adult: Details unknown.
