Eight Spot Skimmer Dragonfly

We have returned to Roche Harbor, and I found this Skimmer on the boat's electrical cable which really provided a perfect background!

The Eight-spotted Skimmer (Libellula forensis) is a dragonfly of the skimmer family. It has two black spots on each wing for a total of eight, and can be distinguished from the similar Twelve-spotted Skimmer by counting the spots. Adult males are additionally adorned with opaque white spots between the black ones. It can be found west of the Rocky Mountains near muddy bottomed ponds and lakes.
