Heterarthrus cuneifrons Altenhofer & Zombori, 1987
[Hymenoptera: Tenthredinidae]

Heterarthrus cuneifrons Altenhofer & Zombori 1987.

Leaf miner: A large, practically full depth blotch without an apparent initial corridor, starting in the centre of a leaf. The full grown larva makes a circular cocoon, attached to upper epidermis. Before that a circular cut has been made in the upper epidermis. The completed cocoon falls out of the mine together with the disk of upper epidermis (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 Bladmineerders van Europa.

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

Adult: Details unknown.
