Pseudocneorhinus bifasciatus
twobanded Japanese weevil, two-banded Japanese weevil
Pseudocneorhinus bifasciatus is an invasive broad-nosed weevil native to Japan that has established populations in the United States. First detected near Philadelphia in 1914, it is believed to have arrived via infested nursery stock. The species has since spread throughout the northeastern, midwestern, and southeastern United States, with documented presence in at least 11 states. It is recognized as a significant pest of ornamental and landscape plantings due to its broad host range.
