Scolioneura betuleti

    Alternative names
    Scioloneura vicina

    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. 

    Identification difficulty

    Tenanted leaf mines occur between August and October.

    When to see it

    Larval mines may be encountered when the larval foodplants are in leaf.
