The species is found in decidous woods, on wood edges, frequently also in gardens and especially in orchards. Adults are on the wing in two generations in April and May and again in July and August, at least in central Europe. Correspondingly, larvae are found in June and July and again in September and October (Kurz & Kurz 2019). The pupae of the second generation hibernate.

Larva. The larvae are bright green. They feed on the leafes of Malus baccata, Malus domestica, Malus sylvestris and Pyrus communis. The mine starts as a narrow corridor, often following a vein or the leaf margin. Later sections are much wider and contorted, often forming a secondary blotch. The frass is concentrated in a narrow central line. There may be several mines in a single leaf (Nieukerken 2016).
