Interpretive Summary: The twobanded Japanese weevil, a pest of ornamental plants, was introduced into the United States in 1914 in Pennsylvania, but the spread of this insect has not been documented in the southeast. We looked at museum records and collected the weevil in the southeast to document its southeastern spread. The information will help other scientists understand the movement of this weevil and will inform nursery growers of the presence of this potential pest in the southeast.

Technical Abstract: The twobanded Japanese weevil, Pseudocneorhinus bifasciatus Roelofs, first found in North America at Philadelphia, Pennsylvania, in 1914, is better known in the northeastern United States than in the Southeast. Based mainly on museum records (11 insect collections were examined) and fieldwork, we report the weevil from Alabama (3 counties), Georgia (12), North Carolina (16), and South Carolina (18). The southeastern distribution is mapped, and locality and date are provided for the first collection known for each state: North Carolina, 1955; Georgia, 1956; South Carolina, 1966; and Alabama, 1970.
