New distribution records for all three Nearctic species of Phragmatobia include state records (the first records for the states indicated) of P lineata (Maryland, Wisconsin); P fuliginosa rubricosa (Ohio, South Dakota), and P assimilans (Idaho, Montana, Pennsylvania, Wisconsin), all representing southern range extensions at those longitudes except for the Wisconsin records of P lineata, which are northern range extensions. Chelone glabra (Scrophulariaceae) is reported as a larval hostplant of P lineata, and descriptive notes on the larva of this species are included. Midwinter activity of a larva crawling on snow is reported for P fuliginosa rubricosa. The rare original description of Phragmatobia dallii Packard, 1870, is reproduced.
