The larvae feed on the leaves of Dryas octopetala exclusively. The mine consists of a narrow corridor, descending towards the base of the leaf while following the leaf margin. Later, the corridor reverses its direction, and widens into a blotch that may occupy half of the leaf. The frass is concentrated in the corridor as a broad central ribbon and is broadly scattered in the blotch (Nieukerken 2016).
