Food Plant: Tilia (Lime); in Europe Acer platanoides (Norway Maple)

Egg: Underside of leaf

Mine: July - August (bivoltine in the south in some years)

Notes: A narrow mine almost filled with black frass, usually following leaf-vein. The larvae ;window' feed on the leaf once they have left the mine (as shown) and form small white moulting cocoons, between instars (three are shown). The final cocoon is formed either on the trunk of the tree or in leaf litter. Mine illustrated is on small-leaved lime (T.cordata).
