Quercus pubescens
The larvae feed on "Quercus ilex", "Quercus petraea", "Quercus pubescens", "Quercus pyrenaica", "Quercus robur" and "Quercus suber". They mine the leaves of their host plant. The mine consists of a slender corridor with a narrow frass line. The mine cannot be distinguished from the mines of "Stigmella roborella" and "Stigmella atricapitella".
