Leaf miner: The initial mine is usually in the form of a gallery, which expands to form a blotch. (British leafminers).

Large, almost full depth blotch with scattered frass. The mine is identical to that of M. pumilus, but the larva is different (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).

Larva with two ventral spots, whereas M. pumilis has two (British leafminers). The larva is also illustrated in Bladmineerders van Europa.

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

Adult: Details unknown.
