Enallagma Eiseni
''Enallagma'' is a genus of damselflies in the family Coenagrionidae commonly known as bluets. Adults range in length from 28 mm to 40 mm. Males are usually bright blue and black while the coloration of females varies by species. Bluets can be distinguished from the similar vivid dancer by wing position; at rest, bluets' wings hang down on either side of their body, while vivid dancers hold their wings above their body. Bluets also have shorter leg spines. Subspecies The genus consists of the following species: *''Enallagma ambiguum'' *'' Enallagma anna'' – River Bluet *'' Enallagma annexum'' – Northern Bluet *'' Enallagma antennatum'' – Rainbow Bluet *''Enallagma aspersum'' – Azure Bluet *'' Enallagma basidens'' – Double-Striped Bluet *'' Enallagma boreale'' – Boreal Bluet *'' Enallagma cardenium'' – Purple Bluet *'' Enallagma carunculatum'' – Tule Bluet *'' Enallagma civile'' – Familiar Bluet *'' Enallagma clausum'' – Alkali Bluet *'' Enallag ...

Enallagma Exsulans
The stream bluet (''Enallagma exsulans'') is a species of American bluet damselflies in the family Coenagrionidae. Its length is 29–37 mm. Many bluet species prefer ponds and lakes; the stream bluet as its name implies is most at home along moving waters. It can be found along small to medium-sized rivers. It is occasionally found at lakes too. In many species of damselflies the males have a blue tip to the abdomen. ''Enallagma exsulans'' is one of those less common cases where the female, too, has a blue abdominal tip. Summertime is the best time to look for stream bluets.
