Although late in the year, still managed to add another to the year list last week in the shape of Phyllonorycter strigulatella leaf mines on Grey Alder.
Whilst many leaves had already fallen, those that remained held plenty of mines from this species as well as those of P. rajella, P. kleemannella and P. stettinensis.
