The preceding photographs show a Great Blue Skimmer dragonfly (Libellula vibrans) spotted along “Great Blue Heron Trail” during a photowalk at Accotink Bay Wildlife Refuge, Fairfax County, Virginia USA. This individual is a mature male (as indicated by its coloration, terminal appendages, and tattered wings) that has mated many times.
Males that have mated often have marks on their abdomen where the female legs have scratched them. This is especially obvious in species in which males develop pruinosity, as the pruinosity on the midabdomen is scratched off, and the signs are visible at some distance.

Great Blue Skimmers are one of many types of dragonflies that perch with their front legs tucked behind their eyes/head.
