Blue-eyed Darner


Erika spied a pair of Blue-eyed Darners on 10 June 2019. These dragonflies hung under a vetch along a trail at the Nisqually National Wildlife Refuge near Olympia. Readers of this blog may recall that most dragonflies mate with the female collecting semen from the male, while he grasps her by the back of her neck. Dragonflies often fly about in this wheel position. This behavior prevents other males from mating with the female. One of the first things another male does is flush semen from the females with whom they are about to mate.

Blue-eyed Darners are common across much of the western United States, and barely into adjacent Canada and Mexico. They are found in all sorts of wetlands, even venturing into urban areas. They do, however, prefer open, rather than forested, habitat.
