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 an irregular, broad corridor. The frass is concentrated in a broad frass line that almost fills the gallery, leaving only a narrow transparent zone at either side. Pupation takes place outside of the mine.
