Star Spangled Fourth


A Spangled Skimmer dragonfly (Libellula cyanea) spotted during a photowalk through Huntley Meadows Park, Fairfax County, Virginia USA. The Spangled Skimmer is differentiated from similar blue dragonflies by the black and white pterostigmas located on the leading edge of all four wings, toward the wingtips. Photo 1 of 2 is a copy of the original photograph, annotated to highlight the pterostigma on the left hindwing (facing forward); Photo 2 of 2 is the original photograph.

Tech Tips: Adobe Photoshop was used to sharpen the original image. Apple Preview was used to annotate the photo.
