A Twelve-spotted Skimmer dragonfly (Libellula pulchella) was photographed along the boardwalk at Huntley Meadows Park on 10 September 2014. This individual is a young adult male, as indicated by its partial pruinescence, distinctive pattern of wing spots, and terminal appendages. As a mature adult male dragonfly, its abdomen will be completely covered by white pruinescence.
Among dragonflies that exhibit sexual dimorphism, such as Twelve-spotted Skimmers, immature/young males and females are similar in appearance. The pattern of wing spots is a key field marker for identification of Twelve-spotted Skimmer males and females, in addition to differences in their terminal appendages.
I love a good shot of a head-tilt!
