In its native range, "A. glabripennis" primarily infests plants like maple, poplar, willow, and elm trees. In the United States, "A. glabripennis" has completed development on species of these genera and also "Aesculus", "Albizia", birch, katsura, ash, planes, and "Sorbus". In Canada, complete development has been confirmed only on maple, birch, poplar, and willow, although oviposition has occurred on other tree genera. Maple is the most commonly infested tree genus in North America, followed by elm and willow. In Europe, complete development has been recorded on maple, "Aesculus", alder, birch, hornbeam, beech, ash, planes, poplar, "Prunus", willow, and "Sorbus". The top five host genera infested in Europe, in decreasing order, are maple, birch, willow, "Aesculus", and poplar. Not all poplar species are equally susceptible to attack.
