Blue Dasher (Pachydiplax longipennis)


Arthropoda > Insecta > Odonata > Libellulidae


A common medium-sized species found throughout North America around ponds and lakes from March to November. The males are blue-bodied with blue eyes, a white face, and clear wings containing a dark stigma. Species similar to the male include the Western Pondhawk which has a green face, the Comanche Skimmer which has white stigma, and the Bleached Skimmer which has more washed-out appearance and paler eyes. The female is fairly distinct, black with pale blue eyes and a series of yellow quadrate lateral markings. Another blue species, the Plateau Dragonlet (Erythrodiplax basifusca), has been recorded just once in California (Imperial County): that species is distinct in having black thorax, head, and eyes, but is unlikely to be encountered here.
