A Great Blue Skimmer dragonfly spotted near the suspension bridge over Accotink Creek, Accotink Bay Wildlife Refuge. This individual is an old female, as indicated by its gray-brown coloration, the flanges beneath its eighth abdominal segment (used to scoop and hold a few drops of water during oviposition), and by the terminal appendages at the end of its abdomen. "Females become duller and darker with age, eyes may become blue." Source Credit: Paulson, Dennis (2011-12-19).
