Phyllonorycter alpina is a moth of the Gracillariidae family. It is found from Germany to Italy and from France to Ukraine.
The larvae feed on Alnus viridis. They mine the leaves of their host plant. They create a lower-surface, long and narrow tentiform mine, usually between two lateral veins. The lower epidermis has one or more strong folds. The frass is deposited in a clump in the angle of the mine closest to the midrib. The cocoon is white and peppered with frass grains.
