Specimens in nature


An elongated, tentiform mine on the underside of a leaflet, some distinct longitudinal folds. The mine is much contracted, especially in small leaves where it can even occupy the entire surface. The upperside is yellowish green. The frass is concentrated in a corner of the mine. Depending on the host plant, the mine is parallel with the leaf margin (Sorbus) or it is situated between two secondary veins (Prunus).
