Food Plant: Betula (Birch), Carpinus (Hornbeam), Corylus (Hazel), Malus (Apple) and other deciduous trees.

Mine: May-June

Notes: A distinctive blotch mine is produced, then the larva falls to the ground inside a case made from the cut-out. The photo above shows the young larva (2mm) from its first case - dorsal view, top and ventral view, bottom photo. The pattern of the sclerotizations changes as the larva matures.
