Common Green Darner female

Green Darners are one of our largest dragonflies, and one of the easiest to recognize. Their bodies grow over three inches long, with a wingspan of 4 1/2 inches.

Green Darners are dimorphic, which means males and females look different. Both sexes have a green thorax (middle section of body), but males have a blue abdomen (long back part of body), while females' abdomens are purplish-gray.

Both males and females have a mark like a target on their faces. Green Darners' eyes are brown.

Green Darners are found around ponds, lakes, marshes, and slow-moving streams.
