One species of this Nearctic genus -Amphiagrion saucium
Walker(1953) lovingly described these larvaeas "a small dumpy short-legged nymph of nearly uniform olivaceouscolour and with angular postocular lobes" (p. 163). Specimens arefound in small pockets of water in spring bogs and small runningstreams, a habitat that Walker earlier recognized as beingdeleteriously impacted by human activities that lower water tables.Populations tend to be localized due to narrow habitat preferences,but is widely distributed in North America. Adults emerge in earlyJune and adults can be caught through July.
