Lotus sp., Drachten © Gerrit Tuinstra: the elongated form of the frass grains seems to be a charater of Leucoptera species.

mine

Egg at the upperside of the leaf. The mine is an upper-surface blotch without anything like a preceding corridor. The blotch is about circular, but my have broad lobes. Black frass grains lie in indistinct arcs or spirals, glued to the upper epidermis, and forming a dark central patch. The larva can leave a mined leaf, and restart elsewhere. Pupation external.
