Leaf miner: Large, deep, upper-surface blotch that starts at the leaf margin, without an accumulation of frass. Around the oviposition site the leaf turns reddish brown. Frass in scattered grains, but towards the end of the larval period an opening is made in the mine, and both frass and exuvia are ejected. About that time the mined leave is shed, and the larva makes a disk-shaped cocoon within the mine, in which it diapauses until the following spring (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.

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

Adult: Details unknown.
