Coenagrion is a genus of damselflies in the family Coenagrionidae, ^[2] commonly called the Eurasian Bluets (although three species are found in North America: Coenagrion angulatum , Coenagrion interrogatum , and Coenagrion resolutum ^[3] ). Species of Coenagrion are generally medium-sized, brightly coloured damselflies. ^[4]

Biology

Thermal adaptation

This genus's capacity for phenotypically plastic responses to the surface air temperature is important to species' ranges. ^[13] These thermal responses will also decide a great deal of these species' responses to climate change. ^[13] Nilsson-Örtman et al., 2012 find a high degree of thermal adaptation in high latitude populations of Coenagrion. ^[13] They found similar plasticity even for various sympatric species at the same locations, and despite the highly variable weather at such latitudes. ^[13]
