Enallagma is a genus of damselflies in the family Coenagrionidae commonly known as bluets. 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.[1]
Description
[edit]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.

[edit]Enallagma doubledayi, the Atlantic bluet, is a species found in the Caribbean and North America. The IUCN conservation status of Enallagma doubledayi is "least concern", with no immediate threat to the species' survival. The population is stable. The IUCN status was reviewed in 2017.
