Zeugophora subspinosa (Fabricius, 1781)

mine

For all the western european Zeugophora species applies: large, blackish brown, upper-surface blotch. Oviposition at the leaf underside, in a small pit, that is covered by secretion. These oviposition marks remain visible as small, transparent points. Larva yellow, flattened, with a distinct head but no feet. They live communal, and leave the mine through an upper-surface exit slit.

According to Augustin (1998a) the commonest Zeugophora.
