Blue Dasher, male

Pachydiplax longipennis


The males are easily recognized due to the yellow-striped thorax, metallic-green eyes, mostly white face, and pale blue abdomen, often with a dark tip. Females and immatures also have a yellow-striped thorax, but the abdomen has a longitudinal yellow and brown/black pattern. The eyes are reddish brown above and blue-grey below. Females have a short, blunt abdomen, while the abdomen of juveniles is longer and thinner and tapered at the posterior end. Older females may resemble worn males as their abdomen turns blue-grey and the eyes acquire a greenish tint (

The darker tip to the abdomen, striping on the sides of the thorax and amber patches on the wings are consistent with a male Blue Dasher. :-)
