    Blue Dasher - (Pachydiplax longipennis)

    The fast Blue Dasher is one of the most commonly sighted dragonflies in all of North America.

    Staff Writer (8/11/2017): Blue Dashers are one of the most abundant dragonflies in the U.S. and can be found near slow moving water sources, marshes and ponds. Adults have four wings with two noticeable dark streaks in them. They have a striking blue color ending in a black tip on the abdomen.

    Their heads contain their large eyes which take on a metallic look. The female differs somewhat from the male in that her wings do not contain the aforementioned stripes and their abdomens are stubbier. Females are further distinguished by their abdomen coloring that can also be seen with yellow stripes along the sides and top. The thorax has yellowish-green striping as well.

    Juvenile Blue Dashers are not blue yet. They have green and yellow stripes on the thorax and yellow dashes along the side of the abdomen.

    Males are often seen around water's edge, protecting their territory from other males. They will flash their blue abdomens as a threat to each other. Females usually perch on vegetation and only approach the water when they are ready to mate. Both genders stick their abdomens upright in the air when perched, as if on alert, and snap their wings closed after settling down.

    Like other dragonflies, the eco-friendly Blue Dasher contributes to pest control by consuming hundreds of smaller insects each day.
