willow leaf beetles
Plagiodera is a genus of leaf beetles in the subfamily Chrysomelinae, containing approximately six recognized species distributed across the Holarctic region. The genus is best known for Plagiodera versicolora, commonly called the imported willow leaf beetle, which has been introduced to North America from Europe and is a significant pest of willow and poplar species. Members of this genus are specialized herbivores of Salicaceae, with well-documented chemical ecology and host-plant interactions.
