It is getting to be that time of the year when certain dragonfly species, like the Common Green Darner (Anax junius), begin to migrate southward. Most people are aware of the migration of Monarch butterflies, but are surprised to learn that some dragonflies also migrate.
The Science News website described this amazing migration in an on-line article, “At least three generations make up the annual migration of Common Green Darner dragonflies. The first generation emerges in the southern United States, Mexico and the Caribbean starting around February and flies north. There, those insects lay eggs and die, giving rise to second generation that migrates south until late October. (Some in that second generation don’t fly south until the next year, after overwintering as nymphs.) A third generation, hatched in the south, overwinters there before laying eggs that will start the entire process over again.”
Last week I spotted a formation of helicopters flying in formation overhead as I was searching for dragonflies at Occoquan Bay National Wildlife Refuge. For a moment the helicopters, which look to be UH-60 Black Hawk helicopters, reminded me of migratory dragonflies. Before long their loud engines disturbed my reverie and I realized that they were probably flying to Fort Belvoir, a nearby military base.
The image I captured of the helicopters may look like it was turned into black-and-white after the fact, but that was actually the way that it came out of the camera. I really like the stark, monochromatic feel of image that works well with the subject.
