In older mines the caterpillar also eats the palissade parenchyma causing the leaf to fold over the mine and the upper surface of the leaf to change colour, sometimes to transparant whitish.
The dark brown pupa lays in a thin-walled cocoon, attached to the floor of the mine, while all the frass is concentrated in the opposite corner. The species hibertanes in the pupal stage.
