The blue weevil (Ischnoterapion virens), discovered in Pennsylvania in 1994, has since spread across 700 square miles, and is found in parts of 7 states (PA, NY, NJ, DE, VT, MA and MD). This weevil attacks red clover (Trifolium pratense) and white clover (Trifolium repens), causing damage by tunneling in stolons and stems. It is classified as a secondary pest of clover in its native Europe. Dispersal is by movement of nursery stock, hay bales with infested clover, and soil with infested stolons. Surveys and seasonal history studies are ongoing.
