How Many Dragonfly Species Are There?

The most defensible current answer is approximately 3,112 described living species of true dragonflies. That number applies to Anisoptera, not to the entire order Odonata.

The remaining three species in that dataset belong to Anisozygoptera. These figures are dated snapshots rather than permanent totals. Researchers continue to describe species, combine names that prove to be synonyms, transfer genera between families and revise relationships using new morphological and molecular evidence.

Dragonflies Within the Order Odonata

Odonata is the insect order that includes dragonflies, damselflies and the small living lineage traditionally called Anisozygoptera. In ordinary English, “dragonfly” normally refers to an adult member of Anisoptera, while “damselfly” refers to Zygoptera.

Some scientific frameworks have grouped Anisoptera and Anisozygoptera together under the name Epiprocta. The 2026 classification used for this page retains three living suborders. The three living Epiophlebia species should not be described as primitive “half-dragonflies” or as a simple evolutionary bridge between modern damselflies and dragonflies.

Anisoptera is currently divided into four superfamilies: Aeshnoidea, Gomphoidea, Cordulegastroidea and Libelluloidea. Within those superfamilies, the 2026 framework recognizes 20 families. Older books and websites may show fewer families because several lineages previously placed in broad families such as Corduliidae or Synthemistidae have since been separated.

What Do Family, Genus and Species Mean?

“Type of dragonfly” is useful everyday language, but it is not a formal taxonomic rank. A person asking about types may mean broad groups such as darners and clubtails, scientific families such as Aeshnidae and Gomphidae, or individual species such as the Common Green Darner.

A family groups related genera and normally ends in “-idae.” A genus contains one or more closely related species. A species is the basic named unit used in biological classification. Scientific species names contain the genus followed by the specific epithet, as in Anax junius.

Common names are less consistent. One species may have different English names in Britain, North America, Australia or other regions. The same informal group name may also be applied differently by separate field-guide traditions. Scientific names are therefore essential when comparing records from different countries.

Major Dragonfly Families

The following families include several of the groups most often encountered in general field guides. Their typical features are useful starting points, but no single feature identifies every member of a family.

The counts above sum to 3,112 Anisoptera species in the cited dataset. They are included to show relative diversity, not as permanent limits for each family.

Representative Dragonfly Species Around the World

A useful global guide should not imply that a short list represents every important species. The examples below were selected to show different families, regions, habitats and identification problems.

Why Dragonfly Species Differ by Region

Dragonfly diversity is not evenly distributed. The 2026 global synthesis found especially high Odonata richness in the Neotropical, Australasian and Indo-Malayan biogeographic realms. Tropical regions contain many specialized freshwater habitats and often provide long seasons in which adults can feed and reproduce.

Climate alone does not determine local diversity. Flowing forest streams support different families from temporary rain pools, peatlands, alpine wetlands, large lakes or desert springs. Elevation, water chemistry, vegetation, seasonal rainfall, permanence of water, surrounding land cover and biogeographic history all influence which species can occur.

Recorded diversity also depends on survey effort. A country with active field recording, museum collections and modern identification resources may have a more complete checklist than a poorly surveyed tropical region. Continued species descriptions suggest that additional diversity remains undocumented, especially in tropical areas.

This is why a dragonfly described as “common” in Britain, the eastern United States or southern Africa should not automatically be called common worldwide. Even widely distributed species may be abundant in one habitat and absent from another nearby habitat.

Dragonflies vs. Damselflies

Dragonflies and damselflies belong to Odonata, but true dragonflies are classified in Anisoptera and damselflies in Zygoptera. Adult dragonflies are often more robust, and most hold their wings spread when resting. Most damselflies are more slender and commonly bring their wings together or partly together.

Eye position is another useful general clue. The compound eyes of many dragonflies meet broadly or approach each other on top of the head, while damselfly eyes are normally well separated. Gomphidae is an important dragonfly exception because clubtails also have distinctly separated eyes.

These are field rules of thumb, not definitions of taxonomic rank. Classification depends on a much larger body of anatomical and genetic evidence.

How Scientists Classify New Dragonfly Species

A new species is not established simply because an individual has an unusual color. Taxonomists compare specimens with previously described species, published descriptions, museum type material and records from related populations.

Later studies may show that two named species are synonyms, that one apparent species contains several hidden species, or that a genus belongs in another family. Taxonomy is therefore a continuously tested scientific framework rather than a static list.

How to Find Dragonfly Species in Your Area

A regional checklist or field guide is more useful for practical identification than a worldwide color chart. Begin with the species documented in your country, state, province or recording region, then filter them by habitat, date and structural features.

Record the exact location, date, water-body type, behavior and approximate size. Photograph the dragonfly from above and from the side, including the whole wings, thorax, abdomen tip and head when possible. Difficult groups may require close examination of wing venation or reproductive structures.

Follow the complete dragonfly identification process before assigning a species name. Additional background is available in the dragonfly habitat guide, the main dragonfly facts guide, and the guide to the largest living dragonflies.
