General Description

Blue or green notched stripes on lateral sides of thorax (Figure 2). Very similar in appearance to Canada Darners (A. canadensis) but different by having a larger size,a notched posterior thoracic stripe, and a black horizontal line bisecting the frons. They are easily differentiated from other congeneric species by their large sizes and their thoracic stripe pattern(Paulson, 2009).
