Coenagrion is a genus of damselflies in the family Coenagrionidae.[2] Species of Coenagrion occur throughout the Holarctic, including Europe, Asia and North America.[2] They are commonly known as the Eurasian bluets, although several species also occur in North America.[3]

Members of Coenagrion are small to medium-sized damselflies, typically blue and black in colour, and are often associated with ponds, lakes and slow-moving freshwater habitats.[4] The genus includes some of the most widespread and familiar damselflies of the Northern Hemisphere, including Coenagrion puella, Coenagrion pulchellum and Coenagrion hastulatum.[2]

Description

Species of Coenagrion are slender damselflies with narrow wings held closed over the abdomen when at rest.[4] Males are typically bright blue with black markings, while females may be blue, green, brown or pink depending on the species and colour form.[4] Most species inhabit still or slow-flowing freshwater environments, where the larvae develop among submerged vegetation.[4]

Taxonomic history

The genus Coenagrion was established by Kirby in 1890 as part of his revision of the damselflies formerly included in the broadly defined genus Agrion.[1] In the same work Kirby recognised the subfamily Coenagrioninae, from which the family name Coenagrionidae is derived.[1]

Coenagrion remains the type genus of Coenagrionidae and is one of the principal genera of the family.[5][6]

Species

The following species are currently placed in Coenagrion:[2][7]

Biology

Thermal adaptation

This genus's capacity for phenotypically plastic responses to the surface air temperature is important to species' ranges.[11] These thermal responses will also decide a great deal of these species' responses to climate change.[11] Nilsson-Örtman et al., 2012 find a high degree of thermal adaptation in high latitude populations of Coenagrion.[11] They found similar plasticity even for various sympatric species at the same locations, and despite the highly variable weather at such latitudes.[11]

Etymology

The genus name Coenagrion combines the Greek κοινός (koinos, "common") with Agrion, the name of a related genus.[12]
