Dusky Clubtail

On 2 June 2017, Erika and I visited one of our favorite dragonfly spots. The Lebanon Hills Regional Park in Dakota County consists of about a dozen lakes nestled among urban sprawl. The lakes are surrounded by forest and the water seems be in fairly good condition, thus the dragonfly diversity. This day brought us a fair number of dragonflies, but relatively few species.

One I had only seen once before was this Dusky Clubtail. The first time was on 2 June 2015 in Washington County. At first this dragonfly perched on a branch at about eye-level. Then it flew almost to the forest floor. The species is known to perch on or near the ground. It proceeded to raise its abdomen skyward, until it appeared to be almost standing on its head. This behavior is probably a form of obelisking, in which odes attempt to keep cool during hot days by pointing their abdomens to the sky. At 90 degrees F, this day was, indeed, hot.
