I love to see dragonflies with patterned wings and so I was delighted to spot this male Twelve-spotted Skimmer dragonfly (Libellula pulchella) on Tuesday at Occoquan Bay National Wildlife Refuge. The males of this species have a beautiful combination of brown and white patches on their wings.

I used to be confused about the name of the species, because there appear to be a total of twenty-two spots. To make things worse, this species is also known as the Ten-spot Skimmer. What? It apparently depends of how you count the spots. If you count only the brown spots that are present on both males and females, you get twelve spots, but if you count the white spots that are present on only the males, you get ten spots. Yikes! Who knew that math was so important in dragonfly identification. 🙂
