Quercus pubescens
The larvae feed on "Quercus castaneifolia", "Quercus cerris", "Quercus petraea", "Quercus pubescens", "Quercus robur" and "Quercus rubra". They mine the leaves of their host plant. The mine consists of a long, slender corridor. In the first part the frass is concentrated in a narrow line.
