Leaf-mine: Full depth, initially a much branched corridor, irregular in width, in the end almost a blotch. The mine has openings by which part of the frass is ejected. The larvae frequently leave the mine to restart elsewhere. Older larva live free and cause window feeding, often erasing their old mines. In Coltsfoot also pseudo-mines are made, when the larva eats away the lower epidermis with the leaf tissue, but spares the dense hair cover (Bladmineerders van Europa).

Larva: Elongate, without feet, but with a recognisable head capsule (Bladmineerders van Europa).

Puparium: Details unknown.

Comments: Ranunculus ficaria is treated as Ficaria verna (Lesser Celandine) by Stace (2010).
