The Twelve-spotted Skimmer (Libellula pulchella) is a large, obvious, and fairly common dragonfly across the entire U.S. The male has three black patches on each wing; white patches develop between these black patches on mature individuals. Females have a brown thorax with yellow lateral stripes with similar wings to the male but lacking the white patches. This pretty lady was just hanging around and happily posed for me without any anxiety whatsoever. This was taken in my back yard in Rockaway, NJ using a Kodak Z812 IS digital camera.
