Leaf miner: A large blotch mine is formed from the tip of a leaf (as shown). The pupa is formed in the disc - as above (top right). The species has a long feeding period, more than two months (similar to Heterarthrus nemoratus).

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.

Comments: Heterarthrus leucomela is treated as a junior synonym of Heterarthus aceris in Bladmineerders van Europa, but not in ECatSym - Electronic World Catalog of Symphyta.

Hosts in Great Britain & Ireland:
