Boreal Bluet (Enallagama boreale) or
Northern Bluet (Enallagama annexum)

NOTE: Northern and Boreal Bluets are indistinguishable in the field without close inspection according to 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. See Nothern Bluet .
