Cosmopterix lienigiella is a moth of the Cosmopterigidae family. It is found from Fennoscandia to Spain, the Alps and Greece and from Ireland to Ukraine. It is also present in eastern Russia and Japan. It is the type species of the Cosmopterix genus.
The wingspan is 10–13 mm. Adults are on wing from September to April.
The larvae feed on Phragmites australis. They mine the leaves of their host plant. The mine starts as a gallery, but soon widens to a broad blotch, entirely or partly running upwards, in the end half as wide as the leaf. Most frass is concentrated in the first section. Pupation takes place in a cocoon in the top section of the mine.
