The thorax is brown with two narrow, straight, pale yellow to white stripes. On young individuals there are two similar stripes on the upper (dorsal) surface, but these fade with age. The abdomen is brown with blue spots on males, blue or green spots on females. The blue spots may be gray during cool temperatures. The cerci on the female are narrow and as long as the 9th and 10th abdominal segments together. Males have paddle-type claspers. There is a small, opaque, brown spot at the base of each wing.

Two field guides, Dragonflies of the North Woods (2003) and Dragonflies through Binoculars: A Field Guide to Dragonflies of North America (2000), state that springtime darner has blue eyes. BugGuide.net states that the eyes are “generally blue.” All of the photos in both field guides and on the Websites BugGuide.net, Odonata Central, and Wisconsin Odonata Survey, show either brown eyes or mostly brown eyes with a small blue area. My photos show brown eyes. The eye color would best be described as “brown, often with some blue.”

The eyes are brown, often with some blue.

After the common green darner, which emerges in April, this is the earliest darner to emerge in the spring. No other darners emerge before mid-June.
