On Monday I was thrilled to photograph my first dragonfly of the year at Occoquan Bay National Wildlife Refuge, the location that I visit most frequently with my camera. The first prize goes to an immature male Blue Corporal dragonfly (Ladona deplanata)—males turn blue as they mature, but initially they have the same coloration as the females. Blue Corporals of both genders have two light-colored stripes on the front of their thoraxes, the traditional rank military insignia for corporals.

Later in the day I spotted a female Blue Corporal perched on some dry leaves, as shown in the second photo. Can you spot the differences between the dragonflies in the first and second photos? The male abdomen tends to be a bit thinner than the abdomen of the female. However, the biggest difference is in the terminal appendages, i.e. the specific parts at the very tip of their abdomens (their “tails”).

The following day I returned to the refuge and spotted another Blue Corporal perched in some vegetation—I think it is another immature male. Most of the time Blue Corporals like to perch on the ground, but this one looked like it had only recently emerged and may have been waiting for its wings to harden.

When dragonflies undergo their metamorphosis from water-dwelling nymphs to aerial acrobats, their wings are initially very clear and fragile and the creatures are very vulnerable, so I was careful not to disturb the dragonfly when I took a few photos. If you are interested to learn more, check out a 2016 blog posting  Metamorphosis of a dragonfly in which I documented the entire transformation process of a Common Sandragon dragonfly in a series of 15 photos. At the end of that series you will be able to see why I characterized the wings of a newly-emerged dragonfly as “fragile.”
