Anoplus roboris Suffrian, 1840

mine

Oviposition in the underside of the midrib or a thick lateral vein; the oviposition site develops into a large scar. The larva makes a corridor that runs towards the leaf margin. The ultimate part of the mine is a corridor in the leaf tip, with frass in a narrow black central line. Later the leaf often tears in over the mine.

Before pupation the larva vacates the mine by making a very small exit slit (Hering, 1957a).
