The species has a preference for seedlings or very young trees up to 1 m high. Quite often many mines are present on one leaf, causing the leaf to contort. Pupation in a white cocoon inside the mine. The cocoon of the summer generation is rather flimsy, that of the autumn generation is much tougher and strong. The frass is spun together at the other side of the mine. The species hibernates in the pupal stage, within the fallen leaf, between leaf litter on the ground. The pupal skin protrudes from the mine after emergence of the adult.
Adults rest during daytime on tree trunk or in the foliage. They become active towards dusk and come to light.
