Phratora interstitialis

Phratora interstitialis is a species of leaf beetle in the family Chrysomelidae. It is found in Europe and Northern Asia (excluding China) and North America.^[2][3][4] This leaf beetle feeds on host plants that are poor in salicylates (e.g. Salix alexensis and Salix sitchensis)^[4] and is closely related to the European Phratora vulgatissima, which also feeds on salicylate-poor willows.^[5]
