Phratora
Phratora is a genus of leaf beetles (Chrysomelidae) distributed across the Northern Hemisphere in cool, moist regions where their host plants occur. The genus is synonymous with Phyllodecta. Species in this genus feed primarily on willows (Salix), poplars (Populus), or birch (Betula), with host plant associations showing evolutionary conservation—closely related beetle species tend to feed on closely related plant species. European species are difficult to distinguish by external morphology alone and require examination of female genitalia for reliable identification. Several species, particularly Phratora vulgatissima, are economically significant pests of short-rotation coppice willow plantations.
