Rapids Clubtail
Gomphus quadricolor Walsh, 1863

Habitat [-]
The Rapids Clubtail inhabits rapid flowing streams with projecting rocks and a substrate consisting of boulder, rock, gravel, and sand (Walker 1958, Cuthrell 2000). It may also be found in or near slow-flowing, small streams and swiftly-flowing large rivers (Nikula et al. 2003, New York Natural Heritage Program, 2007).

Associated Ecological Communities [-]
  • Cobble shore
    A community that occurs on the well-drained cobble shores of lakes and streams. These shores are usually associated with high-energy waters (such as high-gradient streams), and they are likely to be scoured by floods or winter ice floes.
  • Confined river
    The aquatic community of relatively large, fast flowing sections of streams with a moderate to gentle gradient.

Associated Species [-]
  • Spine-Crowned Clubtail (Gomphus abbreviatus)
