Specimens in nature


A rather small, at first semi-circular or oval, tentiform mine on the upperside of a leaf; later growing into a more elongated mine. The mine does not contort the leaf much; it is yellowish green and has one longitudinal fold in the centre. The mine is often situated on top of a secondary vein. The frass is concentrated in a corner of the mine.
