When the weather gets hot, some dragonflies will raise their abdomens (the “tail”) in what is believed to be an attempt at thermoregulation. I can’t say for sure if it works, but the theory is that in this position, sometimes referred to as the “obelisk,” dragonflies are able to stay cooler by reducing the amount of their bodies subject to direct sunlight.

Earlier this week I spotted this male Eastern Amberwing dragonfly (Perithemis tenera) in a modest obelisk position at Jackson Miles Abbott Wetland Refuge. I characterized the position as “modest,” because sometimes a dragonfly will elevated its abdomen until is almost vertical.
