Large, lower-surface tentiform mine, often occupying the entire space between two side veins, from the midrib almost to the leaf margin, Lower epidermis without clear folds.The larva is grey (all other Phyllonorycters on Alder are white). Pupa in a light brown cocoon that is fastened to the roof of the mine. The cocoon is entirely free of frass: all frass is accumulated in the inner corner of the mine. Before ecdysis the pupa works itself half out of the mine; mostly this is through the lower epidermis.
