Common NameLake Darner
SeasonalityJune to September in British Columbia (Paulson, 2009).
IdentificationBlue 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).
