Great Blue Skimmer dragonfly (adult male)

A Great Blue Skimmer dragonfly spotted along the boardwalk at Huntley Meadows Park. This individual is an adult male. "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."
