Phyllonorycter dubitella is a moth of the family Gracillariidae. It is found from Fennoscandia and northern Russia to the Pyrenees, Italy and Bulgaria and from Great Britain to Ukraine.
The wingspan is about 8 mm. There are two generations per year with adults on wing in May and June and again in August.[2]
The larvae feed on Salix caprea. They mine the leaves of their host plant. They create a large, lower-surface tentiform mine, mostly between two side veins. The upperside is strongly inflated. The underside has many narrow folds. The pupa is light brown and made in a golden cocoon. The frass is deposited in a corner of the mine.[3]
