Blue Dasher

The blue dasher is one of our fairly common skimmers. They are usually found around lakes, ponds or slow moving rivers and streams. These blue dashers were photographed at the William O'brien State Park where the St Croix Rivers overflows into Lake Alice.
These are photos of mature blue dashers. Immature blue dashers are yellowish in color with brown stripes on the thorax. As they age they produce pruinose, a powdery substance, which covers the abdomen and give them their blue color.
