Northern Bluet
Enallagma annexum
The Northern Bluet (Enallagma annexum) is a common and widespread damselfly of much of the United States and Canada. Formerly it was considered Enallagma cyathigerum but has been split into a different species; cyathigerum is now an old world species. The Northern Bluet is absent from the southeast quarter of the U.S. It is a common species on many ponds and marshes. The first shot of a male shown here was taken at Arnprior, Renfrew Co., Ontario, Canada, in July, 2005. The digital image was taken with a Canon EOS 1D Mark II and EF 180mm F/3.5 L lens with a 1.4X extender and 580 EX flash.
The next 7 shots of Northern Bluets were all taken at about 7000 ft elevation in the mountains northeast of Vernal, Utah. The location was adjacent to the Daggett and Uintah Co. lines. These next 7 shots were taken with a Canon EOS 1D Mark III and EF 300mm F/4 L IS lens and 2X extender. The first 4 shots show different males.
