Quercus pubescens, Greece; from van Nieukerken & Johansson (2003a)

mine

Oviposition at the underside of the leaf. The mine is an extremely densely wound corridor, giving the appearance of a brown dot; only the very latest part of the corridor loosens itself from the knot. Frass brown, dispersed, almost filling the corridor.

Usually 2-3, sometimes more, eggs are deposited together. The young mines then are closely intertwined. Mostly a part of the larvae die precociously.
