Pseudodineura enslini (Hering, 1923)
[Hymenoptera: Tenthredinidae]

Pseudodineura enslini (Hering, 1923).

Leaf miner: Makes a full depth blotch mine in which the black frass may be visible. May be several mines in the leaf and the larva may exit one leaf and mine in another (British leafminers).

Large, full depth blotch, starting with a short corridor, that often follows the leaf margin. Often 5-12 mines in a leaf. Mines mainly in the lower leaves. The larva may leave its mine and restart elsewhere. Pupation outside the mine (Bladmineerders van Europa).

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).

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

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