Phyllonorycter cerasicolella is a moth of the Gracillariidae family. It is known from all of Europe, except northern Scandinavia. The wingspan is 7–8 mm. There are two to three generations per year in western Europe. The larvae feed on Prunus cerasifera, Prunus mahaleb and sometimes Prunus spinosa, as well as various cultivated Prunus species. Mines may also occur on Malus species when grown in proximity of cultived Prunus. They mine the leaves of their host plant. They create a lower-surface tentiform mine, usually between two side veins, without clear folds.
