Flaumeiche
The larvae feed on "Castanea sativa", "Quercus castaneifolia", "Quercus cerris", "Quercus frainetto", "Quercus pedunculiflora", "Quercus petraea", "Quercus pubescens" and "Quercus robur". They mine the leaves of their host plant. The mine consists of a fairly long, rather slender corridor. The frass is concentrated in a broad, often interrupted central band.
