The purpose of this study is to revise the genus Suwallia and to evaluate the potential taxonomic importance of adeagal and other genitalic characters, adult pigment patterns and egg characters. The revision concentrates on western North American species while providing coverage of all species, except Suwallia asiatica Zhiltzova and Lavanidova where only presumed females have been available for study. Communication and mate locating behaviors in adult stoneflies are critical for life cycle completion and species perpetuation. Drumming signals are known for numerous species of Plecoptera, but mate searching patterns and specifically, if or how vibrational communication is utilized for locating mates are virtually unknown for all stonefly species. I conducted field or laboratory studies of three species to elucidate mate searching patterns and how vibrational communication is used for locating mates. The species studied included a bushtopper, Suwallia pallidula (Banks); a ground scrambler, Claassenia sabulosa (Banks); and treetopper, Perlinella drymo (Newman). The "fly-tremulate-search". "rock to rock" and "fly-drum-search" search patterns exhibited by these species are described, as well as how vibrational communication is used for mate finding. Vibrational signal production by tremulation is reported for the first time in Suwallia, and for only the second time Plecoptera.
