NOTE: Northern and Boreal Bluets are generally indistinguishable in the field without close inspection. See Paulson (2009) and Kerst and Gordon (2011). There are slight differences in head markings and appendages and the Boreal Bluet is more likely in the Cascades. The term NoBo Bluet is used to signify that it is one of these two.
