Hyperaspis paludicola Schwarz is a rarely collected scymnine coccinellid of the tribe Hyperaspidini. Knowledge of its habits has been limited to an association with the adventive mealybug Miscanthicoccus miscanthi (Takahashi) on Chinese silvergrass (Miscanthus sinensis; Poaceae) in Washington, DC. A second association of H. paludicola with M. miscanthi was observed in Clemson, South Carolina; adults were present on ornamental Chinese silvergrass from August 2010 to June 2012. The potential use of H. paludicola in the biocontrol of M. miscanthi and mealybugs of other bunchgrasses is proposed. I also review the coccinellid's previous distribution, including an over looked record from Massachusetts.
