Epiaeschna heros
The hawkers (or darners in North America) include the largest dragonflies found in North America and Europe, and are among the largest of the dragonflies on the planet.
This is not a Swamp Darner. Swamp Darners have very different abdominal spots and are much larger. It is one of the mosaic darners. It is a female, likely a Shadow Darner (Aeshna umbrosa) because the mosaic spots on the abdomen are so small. A positive ID from these photos is not possible.
Haha yeah. I'm just testing a few things, thought it was an appropriate photo to test with :)
