This is one of two images of this dragonfly. I believe it to be a Great Blue Skimmer. As well, I have performed a meticulous analysis of the wing-pattern, and I am nearly certain that this is the same exact insect as my other post with the orange tail taken 2 weeks apart. I could be wrong on both accounts. If I am right, it is either a maturing specimen, or a seasonal change as Summer is beginning.
