The common whitetail is a widespread species found across much of North America. It has a distinctively short, stout abdomen.
As with many species of dragonflies, male and female common whitetails look quite a bit different.
Mature males have a chalky bluish-white abdomen and single broad dark band per wing.
Females have a brown body with a row of pale yellowish triangular marks on each side of the abdomen. Each wing has 3 evenly spaced dark blotches.
Young males resemble females but have the wing pattern of mature males. They develop the distinctive white abdomen as they mature.
