Distribution

North America: Ontario and Quebec, Canada; high elevations in the eastern United States.

Feeds on willow (Salix spp.).

Host Associations

Salix - plant feeding and presumably larval development on willow .

Herbivore on willow ; contributes to leaf damage and nutrient cycling in riparian .

Similar Taxa

Other Phratora species Phratora contains multiple willow-feeding ; accurate identification requires examination of subtle morphological characters and geographic context.
