Bucculatrix demaryella castaneae Klimesch, 1950

mine

The mine begins at an oval, lower-surface egg. Here begins a short, full depth corridor, often along the midrib or a thick vein. Most of the mine with a thick frass line. The larva soon leaves the mine, and starts causing window-feeding, later earing holes in the leaf. The larval chamber (the space occupied by the larve, while in the mine, obviously free of frass) is more than three times as long as wide.
