Quercus pubescens
The larvae feed on "Castanea sativa", "Quercus castaneifolia", "Quercus cerris", "Quercus frainetto", "Quercus macrolepis", "Quercus petraea", "Quercus pubescens", "Quercus pyrenaica", "Quercus robur" and "Quercus rubra". They mine the leaves of their host plant. The mine consists of a long, slowly widening, slender corridor. Frass completely fills the corridor.
