List of damselflies of the world (Coenagrionidae)
The Coenagrionidae, commonly known as the pond damselflies or Eurasian bluets, is a large family of relatively small, brightly colored damselflies belonging to the order Odonata. This list aims to provide a comprehensive catalog of species recognized within the Coenagrionidae family.
Taxonomy and Classification
The Coenagrionidae family is placed within the suborder Zygoptera (damselflies). The classification of species within the Coenagrionidae family is a dynamic field, subject to revision as new research and phylogenetic analyses emerge. The taxonomy presented here reflects a synthesis of current literature and major databases, but is not definitive and should be considered subject to change.
Genera Included
The list of damselflies of the world (Coenagrionidae) includes all described genera and species within those genera. Due to the size and continuously updated nature of such a list, a complete listing is generally presented on dedicated websites or databases, rather than within a single encyclopedia entry. Notable genera within the Coenagrionidae include, but are not limited to:
- Acanthagrion
- Amorphostigma
- Argia
- Cercion
- Coenagrion
- Enallagma
- Erythromma
- Ischnura
- Nehalennia
- Oxyagrion
- Telagrion
- Xanthocnemis
Geographic Distribution
Coenagrionidae damselflies are found worldwide, inhabiting a diverse range of freshwater habitats including ponds, lakes, streams, marshes, and canals. Their distribution spans from tropical to temperate regions, with varying species richness in different geographic areas. North and South America exhibit particularly high diversity, as do parts of Asia and Africa.
Ecological Significance
Coenagrionidae damselflies play crucial roles in aquatic ecosystems. As larvae (naiads), they are predators of other aquatic invertebrates, contributing to the regulation of insect populations. As adults, they serve as prey for birds, fish, and other insects. Their sensitivity to water quality makes them valuable bioindicators of environmental health.
Conservation Status
The conservation status of individual Coenagrionidae species varies widely. Some species are widespread and abundant, while others are threatened or endangered due to habitat loss, pollution, and climate change. Monitoring population trends and implementing conservation measures are essential for preserving the diversity of this important group of insects.
Further Resources
For a comprehensive and up-to-date listing of Coenagrionidae species, consult reputable online databases such as the Odonata Information Network (Odonata Central), the World Odonata List, and other relevant taxonomic resources. Scientific publications and regional field guides provide further detailed information on the identification, ecology, and distribution of these damselflies.
