Ectoedemia occultella, the small birch leafminer, is a moth of the family Nepticulidae. It has a Holarctic distribution. It is found in most of Europe, east through Russia (where it has been recorded from Murmansk, Karelia, Leningrad, Samara and Tatarstan and Sakhalin) to Japan. It is also present in North America. Mines very similar to that of Ectoedemia occultella have been found on Rosaceae species in Nepal and Japan and these may belong to this species.
