Thanks for the nice picture of a female Eastern Pondhawk dragonfly. Males and females of this species are different colors. The male is pale blue with a green face and white at the tip of his abdomen. Immature males may appear green and blue. The females, as you can see in your photo, are green with some black markings on the abdomen. Pondhawks are beautiful dragonflies and eat lots of pesky insects like mosquitoes and other annoying-to-humans insects. -Naturalist Linda Gilbert
