The Familiar Bluet is a common damselfly with flexibility when choosing a habitat: where there is water, there they will be.
The Familiar Bluet is one of the brightest of blue damselflies. This makes them easy to spot as they quickly dart from plant to plant, looking for smaller insects to eat. Males have blue around their eyes which matches the blue on the thorax. A thick black line runs down the middle of the thorax and it is flanked by two thinner lines. The long, slender abdomen is mostly blue also with dashes of black near the end of each segment. Females have similar body shape and markings, but the blue is replaced with light brown coloring. A female lays fertilized eggs just under the water's surface while the blue male watches over her. Eggs hatch and the naiads (larvae) live underwater, feeding on aquatic plants and debris until they molt enough times to warrant crawling on land. Naiads start out looking more like mini-crayfish or crawdads than damselflies. After more molting, they are winged and head out to feed and reproduce.
Because Familiar Bluets spend part of their life under water, a nearby water source is essential in order to sustain a population. They are not picky about home sites. Familiar Bluets can live near ponds, lakes, creeks, streams, marshes, swamps and even puddles. It doesn't matter if they are muddy puddles that are newly formed after a good rain. Familiar Bluets will take advantage of a new wet habitat. Adults are most active from late spring all the way through autumn.
