this mine bears a treacherous similarity with the one of Roeslerstammia erxlebella,

but the droplet,

and the spotted larva make the difference

Full depth blotch, invariably beginning at the leaf tip or the tip of a leaf lobe or tooth. Oviposition site covered by a black, shining drop of hardened secretion. Frass generally in long threads, but sometimes in elongated granules. Pupa in the mine, not in a cocoon.
