Elachista pomerana is a moth of the Elachistidae family. It is found from Fennoscandia to the Alps and from Great Britain to Romania. The wingspan is 8–10 millimetres (0.31–0.39 in). The larvae feed on Avena fatua, Calamagrostis epigejos, Glyceria fluitans, Phalaris arundinacea and Poa pratensis. The larvae create a mine which begins near the leaf tip and descends towards the base, occupying the entire width of the blade. The pupation takes place outside of the mine.
