The larvae feed on "Amelanchier", "Chaenomeles", "Cotoneaster bacillaris", "Cotoneaster integerrimus", "Crataegus laevigata", "Cydonia oblonga", "Malus x astracanica", "Malus baccata", "Malus domestica", "Malus floribunda", "Malus fusca", "Malus ringo", "Malus sylvestris", "Mespilus germanica", "Prunus avium", "Prunus cerasifera", "Prunus cerasus", "Prunus domestica", "Prunus spinosa", "Pyrus communis", "Sorbus aria", "Sorbus aucuparia", "Sorbus intermedia", "Spiraea x bumalda" and x "Spiraea vanhouttei". In autumn, the larvae make a composite pistol-shaped leaf case. Early in the following spring, a tubular leaf case is made. This case reaches a length of about 10 mm and is positioned vertically on the leaf with a mouth angle of about 90°. Full-grown cases can be found from the end of May to early June.
