In recent years, the weevil has reared its ugly snout in Ohio to attack coneflowers as well as various members of the Silphium genus including compass plant (S. laciniatum), prairie dock (S. terebinthinaceum), and cup plant (S. perfoliatum). The shiny black to brownish-black weevil is a little over 1/4" long with the measurement including an exceptionally long, curved snout. As with all weevils, this beetle's mouthparts are located at the end of their snout. The females insert their snouts into the flower stems to chew a ring of holes around the stem about 1" below the flower head. The flower stem is not completely cut; the damaged stem just breaks-over causing the flower head to hang from the stem on a thin strand of tissue.
