Great Blue Skimmer dragonfly (old female)

A Great Blue Skimmer dragonfly (Libellula vibrans) 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. Remember that all dragonflies and damselflies have a 10-segmented abdomen, numbered from front to back.

Females become duller and darker with age, eyes may become blue. Source Credit: Paulson, Dennis (2011-12-19). Dragonflies and Damselflies of the East (Princeton Field Guides) (Kindle Locations 9196-9197). Princeton University Press. Kindle Edition.
