A very long, winding corridor on the upperside of a leaf, never on the underside, and the mine never crosses itself. Sometimes, the mine occupies the entire leaf surface. The frass is concentrated in a continuous central, rather broad and dark green frass, distinguising it from the narrow, and almost black frassline in Phyllocnistis labyrinthella.
