Acentria ephemerella (Denis & Schiffermüller, 1775)
Some of the larvae that hatch live for a short while as borer in the stem or midrib; later they live free. When the shape of the leaf is suitable they live in a folded leaf margin, secured with silk; thy also can use two or three leaves to makes themselves a transportable case. The larva is fully aquatic. It is no real miner, but the species has been included in Hering’s (1957a) compilation.
