Scolioneura betuleti

    Description

    The larvae of the sawfly Scolioneura betuleti mine the leaves of Birch (Betula) species and those of Green Alder (Alnus viridis).  The mines and larvae are indistinguishable from those of Scolioneura vicina, but S. vicina larvae live from mid-May until mid-June, while the larvae of Scolioneura betuleti are found only from August to October.
