The Blue Dasher (Pachydiplax longipennis), a pond fairy of the still waters of Mission Trails Regional Park, has a wingspan of 48–50 mm. In California, males display a mostly pruinose sky-blue thorax and abdomen, and a distinctive white face with a black spot and jade-green eyes.

Unlike the robust and longer-winged, black-eyed Western Pondhawk perching on or near the ground, the province of the Blue Pirate’s range includes twigs and branches above ground level and extends into tree canopies, where Blue Dashers poise as ornaments, with downward dropping wings. Their flight period (April to November) locally extends a few days into December, foretelling of the winter holidays to come.

Delicate appearance aside, their ability to tolerate low oxygen levels rank Blue Dashers as North America’s most abundant Odonata species.

This aggressive predator daily consumes insect volume over 10 percent of its body weight, and establishes and defends in a single day, multiple territories, including feeding sites. Females deposit 300 to 700 eggs in 35 seconds, under the males’ protective eyes.
