Scolioneura betuleti - Scolioneura betuleti
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.
Tenanted leaf mines occur between August and October.
Larval mines may be encountered when the larval foodplants are in leaf.
Widespread in Britain.
Status in Leicestershire and Rutland not known.
