Leaf miner: Large glassy blotch, beginning as a short full depth corridor along the leaf margin Mine in the tip of a leaf segment. The leaf tissue around the mine often turning dark purple. Much, coarse, frass. Pupation outside the mine (Bladmineerders van Europa).

The mine is also illustrated in 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 and Bladmineerders van Europa.

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

Adult: The adult is illustrated in ECatSym - Electronic World Catalog of Symphyta.
