A small (max. 10 mm), semi-circular tentiform mine on the underside of a leaf, most of the time situated near the leaf margin, which then folds downwards over the mine. The mine of the summer generation has one longitudinal fold, while the autumn generation has a whole series of fine such lines very close to each other. The black frass is either scattered all over the mine, or lays concentrated in one corner of the mine.

The caterpillar of the summer generation constructs a tough, white cocoon which is attached to both the roof and the bottom of the mine and where the frass is used to align the sides of the cocoon. The caterpillar of the autumn generation constructs a much less tough, although larger cocoon in which no frass is used.

The species hibernation in the pupal stage, inside the cocoon, between fallen leaves among leaf litter on the ground.
