Leaf miner: A blotch mine is formed from the leaf edge. The larva feeds dorsal side towards the top of the leaf. This species is thought to have one generation each year (British leafminers).

Very transparant full depth blotch that starts at the leaf margin (there a clump of frass), that finally occupies a major part of the leaf. 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).

Pale colour, with a darker head (British leafminers).

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

Adults: Details unknown.

Hosts in Great Britain & Ireland:

Ranunculaceae

Hosts elsewhere: Currently unknown.

Time of year - larvae: May to September (British leafminers).

Time of year - adults: August (British leafminers).

Distribution in Great Britain & Ireland: Scotland (Edinburgh area) (British leafminers).
