The adult is 2-3mm with 7-8mm wingspan. Wings are mainly white, partly suffused with yellowish orange and marked with black striae and a prominent black pre-apical spot. Larva is translucent suffused with yellow, up to 3.5 mm long. In the spring, eggs are laid on the young leaves where larvae form long serpentine mines.
Leaves: Silvery translucent serpentine mines, twisted leaves, reduction of photosynthetic capacity. Tissue adjacent to the mines can become necrotic, high infestations can affect plant growth
