    Identification difficulty

    Adult Leafmine


    Where Aspen is present.

    When to see it

    There is a single generation, and the adults are on the wing in May and June.

    Life History

    The larva mines the leaves of Aspen (Populus tremula), first galling the leaf petiole, then forming a triangular blotch extending from the midrib. When the leaves change colour in autumn, the mined area often remains a 'green island' even after the leaves have fallen. Parthenogenetic (females only).

    UK Status
