Phyllonorycter heegeriella is a moth of the Gracillariidae family. It is found in all of Europe, except the Iberian Peninsula and the Balkan Peninsula.
The wingspan is 6,5-8,5 mm. Adults are on wing in May and August in two generations in western Europe.
The larvae feed on Quercus petraea and Quercus robur. They mine the leaves of their host plant. They create a very small lower-surface, tentiform mine. The mine is usually situated near the leaf margin or in a leaf lobe. Mines of the summer generation have one fold, those of the fall generation have a large number of fine wrinkles. The pupa is made in a cocoon. The summer cocoon is small and white and fastened to both the floor and the ceiling of the mine. The cocoon made by the autumn generation is larger, yet more delicate, and is completely free of frass.
