Blue Dasher- Pachydiplax longipennis- L= 1 3/8 to 1 13/16 inches This blue dragonfly is small to medium in size with a white face, a black tip to the abdomen, and a black-and-yellow-striped thorax. Females are recognized by the narrow yellow parallel stripes on the abdomen. Both sexes have an amber patch at the base of each hind wing. Fully mature males are powdery blue with jade-green eyes. Blue Dashers can be found almost anywhere there is still water. The larva is highly tolerant of wetlands with poor water quality and low dissolved-oxygen levels.
