Powdered Dancer

On Friday, 20 July 2012, Erika and I discovered the Spring Lake Park Reserve in northern Dakota County. This park, called the "hidden jewel" of the Upper Mississippi (Watson), looks over bluffs along the river. On a large rock in a forested area, we photographed a Powdered Dancer. Although records exist from surrounding counties, our record is a first for Dakota County (Odonata Central)!

The "heavily pruinose male [looks] like nothing else" (Paulson). (Pruinosity is the tendency for many odonates to develop a whitish or blue-grayish, waxy, powder-like color on their bodies--mostly on males, but sometimes also on females.) This species, the largest Pond Damsel of the region, is usually found closer to water than the one we found. Mating pairs sometimes lay eggs while under water for over an hour (Dubois).
