Phyllobius argentatus is associated with a broad range of host plant, including examples in the plant families
Salicaceae,
Rosaceae,
Ulmaceae,
Fagaceae, and
Betulaceae. It is widely distributed in Europe, where it may be regarded as a pest of fruit trees and hazelnuts where adult beetles may bite holes in leaves and flowers. The damage is, however, rarely important unless it occurs on young trees and nursery stocks. ==References==
