The blue dasher (Pachydiplax longipennis) is a dragonfly of the skimmer family. It is very common and widely distributed through North America and into the Bahamas. Although the species name longipennis means "long wings", their wings are not substantially longer than those of related species. Females do, however, have a short abdomen that makes the wings appear longer in comparison. The blue dasher grows up to 25–43 mm long. Order: Odonata, Infraorder: Anisoptera, Family: Libellulidae, Species: Pachydiplax longipennis (Burmeister, 1839)
