      Genus Overview
                  
               
                        One species in North America, Clioperla clio.  They tend to be predatory on organisms living among leafpacks.  One study suggests that diet shifts from a herbivore-detritivore in early instars to carnivore diet in later instars.  Growth is rapid and suggests a univoltine life cycle.
