Great Blue Skimmer (mature females)

Two Great Blue Skimmer dragonflies (Libellula vibrans) were photographed during photowalks at Occoquan Bay National Wildlife Refuge (OBNWR), Prince William County, Virginia USA.

Both individuals are mature female, as indicated by their terminal appendages, muted coloration, and tattered wings. They were perching in shady hidey-holes relatively far from water.

Female Great Blue Skimmers have a pair of flanges beneath their eighth abdominal segment that are used to scoop and hold a few drops of water when laying eggs (oviposition), hence the family name “Skimmer.” Remember that all dragonflies and damselflies have a 10-segmented abdomen, numbered from front to back.
