Several Blue-faced Meadowhawk dragonflies (Sympetrum ambiguum) were spotted near two vernal pools at a remote location in Huntley Meadows Park. All of these individuals are males, as indicated by their coloration and terminal appendages.
The next photo shows one of the males perching in the obelisk position.
Many dragonflies [perch in the] obelisk position to limit the amount of sunlight hitting their body and use their wings to shade their overheated thoracic flight muscles. Why not just find a shady spot? If he did he would relinquish his territory and that would reduce his chances for mating.

Regular readers of my photoblog know I’m fond of head-tilts in which the dragonfly seems to display some of its personality, especially when the individual is looking at me. I nicknamed this guy “Paleface” because his face is a lighter shade of turquoise than most male Blue-faced Meadowhawks.
The last three photographs were taken in a dry drainage ditch located near one of the vernal pools. According to the most recent U.S. Drought Monitor update, parts of the Washington, D.C. metropolitan region are “abnormally dry” — one classification category from “drought.”
The Backstory: Teneral Blue-faced Meadowhawk dragonflies were observed at Huntley Meadows Park during late-May and early-June 2016, documented in Previews of coming attractions by Walter Sanford. (Hey, that’s me!) A pull quote from that blog post explains the title of this one.
Blue-faced Meadowhawk dragonflies are classified as a fall species of odonate. In the mid-Atlantic United States, meadowhawks seem to disappear for several months after they emerge during early summer and reappear during fall. Where do they go? No one knows for sure. I speculate Blue-faced Meadowhawks are an arboreal species of dragonfly that returns to the ground/water when it’s time to mate.
It must be time for Blue-faced Meadowhawks to mate, because they’ve returned to terra firma!
