It doesn’t quite live up to its common name here in Vermont. Sites range from lower sections of the Poultney and Hubbarton rivers to larger slower rivers of northwestern Vermont. None of these sites can be considered “rapids,” but rather slower, flatter sections of the rivers, as is the case in New Hampshire as well (Pam Hunt, pers. comm.). Larval sampling has revealed a wider distribution than originally thought. As with Spine-crowned Clubtail (G. abbreviatus), adults may oviposit farther upstream from where most mature larvae and exuviae are found.
