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. With larval lifecycles, eggs do not diapause but hatch after a couple weeks. The larvae are found submerged often far from shore.
