Pseudodineura tenuiserra (Lindqvist, 1949).

Leaf miner: Oviposition at the underside of a thick vein. From this point the larva makes a corridor that quickly widens into a full depth blotch, mostly in the distal half of the leaf. Frass initially in a central line, further on in scattered lumps (Bladmineerders van Europa).

There is normally one mine per leaf (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).

Shaped like a normal caterpillar, not much flattened, with a globular head and the mouth directed vertically (Bladmineerders van Europa).

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

Pupation outside the mine (Bladmineerders van Europa).

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