Blue dasher (Pachydiplax longipennis)

blue dasher

Blue dasher (Pachydiplax longipennis) is a widespread, fairly common, small to medium-sized skimmer. It is found from early June to early September near lakes, ponds, slow streams, ditches, and possibly bogs. It perches on erect, slender plant stems. When perched the wings are lowered. Males joust over water by flying under an opponent and rising, forcing the opponent away from the water surface.

Blue dasher is identified by the powdery blue pruinescence on the tapered abdomen; blackish-brown and yellow striped thorax with no pruinescence; white face; and green or blue eyes.
