Guides
Coenagrion
Eurasian Bluets, Northern Bluets
Coenagrion is a genus of damselflies in the family Coenagrionidae, commonly called Eurasian Bluets or Northern Bluets. Species are generally medium-sized with bright coloration. While predominantly Eurasian in distribution, three species occur in North America: C. angulatum, C. interrogatum, and C. resolutum. The genus exhibits phenotypic plasticity in thermal adaptation, with high-latitude populations showing significant thermal adaptation capacity.
Enallagma
bluets
Enallagma is a genus of damselflies in the family Coenagrionidae, commonly known as bluets. Adults range from 28 to 40 mm in length. Males typically display bright blue and black coloration, while female coloration varies by species. The genus underwent taxonomic revision by Rosser Garrison in 1984. Several species have been studied for their responses to climate change and range expansion dynamics.
Enallagma basidens
Double-striped Bluet
Enallagma basidens, commonly known as the Double-striped Bluet, is a species of damselfly in the family Coenagrionidae. Adults measure 21–28 mm in length. The species is distinguished by a unique black shoulder stripe divided by a thin blue line, a feature found in no other damselfly. It occurs across North America and Middle America.
Enallagma cardenium
purple bluet
Enallagma cardenium, commonly known as the purple bluet, is a narrow-winged damselfly in the family Coenagrionidae. It occurs in the Caribbean and North America. The species holds a Least Concern conservation status with stable populations.
Enallagma clausum
alkali bluet
Enallagma clausum, the alkali bluet, is a narrow-winged damselfly in the family Coenagrionidae. It is native to North America with a documented range expansion westward in western Canada. The species has been studied for parasite-host dynamics involving water mites and gregarines. Its IUCN conservation status is Least Concern with a stable population.
Enallagma divagans
Turquoise Bluet
Enallagma divagans, the turquoise bluet, is a narrow-winged damselfly in the family Coenagrionidae. It is endemic to the United States. The species is classified as Least Concern by the IUCN, with a stable population and no immediate threats to its survival.
Enallagma doubledayi
Atlantic bluet
Enallagma doubledayi, the Atlantic bluet, is a narrow-winged damselfly in the family Coenagrionidae. It occurs in the Caribbean and North America. The species was described by Selys in 1850 and is currently listed as Least Concern by the IUCN, with a stable population as of the 2017 assessment.
Enallagma durum
big bluet
Enallagma durum, the big bluet, is a species of narrow-winged damselfly in the family Coenagrionidae. It occurs in northern Mexico and the southern and eastern United States. The IUCN lists it as Least Concern with a stable population. As a member of the genus Enallagma, it shares characteristics with other bluet damselflies, though specific ecological details for this species remain limited in published sources.
Enallagma ebrium
Marsh Bluet
Enallagma ebrium, commonly known as the marsh bluet, is a North American damselfly in the family Coenagrionidae. It is closely related to E. hageni, with which it forms a mosaic spatial distribution pattern across eastern North America. The species is known to host the water mite Limnochares americana, which can affect its survivorship and maturation. Research indicates that adult damselflies exhibit grooming behavior in response to mite parasitism, with responses varying by age, sex, and mite intensity.
Enallagma exsulans
Stream Bluet
Enallagma exsulans, commonly known as the Stream Bluet, is a species of damselfly in the family Coenagrionidae. It is distinguished from many other bluet species by its strong association with flowing water rather than still ponds and lakes. The species ranges across much of eastern and central North America.
Enallagma geminatum
Skimming Bluet
Enallagma geminatum, commonly known as the skimming bluet, is a species of narrow-winged damselfly in the family Coenagrionidae. The species is found across North America and is classified as Least Concern by the IUCN, with a stable population. It belongs to the genus Enallagma, a speciose group of damselflies that has been the subject of extensive taxonomic research, including a 1984 revision by Rosser Garrison.
Enallagma pollutum
Florida bluet
Enallagma pollutum, the Florida bluet, is a narrow-winged damselfly endemic to the eastern United States. It belongs to the family Coenagrionidae, a large group of small to medium-sized damselflies commonly known as pond damselflies or bluets. The species is classified as Least Concern by the IUCN, with a stable population and no immediate threats to its survival.
Enallagma semicirculare
Claw-tipped Bluet
Enallagma semicirculare, commonly known as the claw-tipped bluet, is a damselfly species in the family Coenagrionidae. It occurs primarily in Mexico and the southwestern United States, with documented records from Arizona, New Mexico, and southern Texas. The species was described by Edmond de Sélys Longchamps in 1876. Like other members of the genus Enallagma, it is a small, slender damselfly associated with freshwater habitats.
Enallagma vesperum
vesper bluet
Enallagma vesperum, the vesper bluet, is a narrow-winged damselfly in the family Coenagrionidae. It occurs in southern Canada and the central and eastern United States. The IUCN lists the species as Least Concern with a stable population.
