Leaf-mine: Long, full depth mine, starting at an oviposition scar, mostly in the distal part of the midrib; the scar may be swollen and gall-like. Frass line variable in width, sometimes quite broad. Usually the corridor loosely follows the leaf margin, and the part of the leaf that is cut off from the centre dies off. The larvae live in spring, when the leaf is unfolding; later in summer affected leaves are recognisable because the tip of the leaf and parts of the marginal teeth are missing, by remnants of the corridor and by a general disfiguring of the leaf. The larva leaves the mine before pupation (Bladmineerders van Europa). Mines of Anoplus plantaris on Betula pubescens Image: Willem Ellis (Bladmineerders van Europa) Larva: Details unknown.
