Additional larval hosts recorded as Betula alleghaniensis Britt. , Populus balsamifera L., Populus deltoides Bartr. ex Marsh , Populus grandidentata Michx. , and Populus tremuloides Michx. , although reports of Populus as a larval host likely indicate misidentification of the similar looking Agrilus granulatus liragus (Jendek and Poláková 2014) .
