Re: Male Common Darter Dragonfly

Thank you Mark; I enjoyed observing this specimen as it basked in the mid-afternoon November Sun; it might still be active because the weather is still mild.

Very interesting. I wonder why the fly doesn't just move to the shade though. That would be far more efficient than this laborious process.
