In early September, 2017, plants growing in a wetland in the study area contained extensive internal excavations in flower buds, shoots, and stems, with some of the tunneled areas containing weevil larvae. Adults emerged from this plant material in late September. Using photos, B. Mathison and V. Belov (2017) identified an adult to species on the BugGuide website.
