Quercus ilex
The larvae feed on "Quercus coccifera", "Quercus ilex", "Quercus ilex rotundifolia" and "Quercus suber". They mine the leaves of their host plant. The mine consists of a narrow corridor, filled with frass, that widens into a large, oval, upper-surface blotch with frass concentrated in its basal part and along the sides.
