Aeshna, [2] or the mosaic darners, is a genus of dragonflies from the family Aeshnidae. Species within this genus are generally known as "hawkers" (Old World) or "darners" (New World).
These are relatively large dragonflies. Their thoraces and abdomens are brown in color, with blue or yellow stripes or spots on the thorax, and yellow, blue or green spots on the abdomen.
Natalia von Ellenrieder's 2003 paper demonstrated that the Holarctic and Neotropical species placed in this genus did not share a common ancestor, and proposed the latter be placed in the genus Rhionaeschna .
The name Aeshna was coined by the Danish entomologist Fabricius in the 18th century. The name may have resulted from a printer's error in spelling the Greek Aechma, "a spear". [3] The spelling Aeschna has been intermittently used over a period of time, but is now abandoned for the original name Aeshna. However, derived genus names (such as Rhionaeschna ) retain the 'sch' spelling, as this is how they were first cited.
Many species formerly included in Aeshna have been split into other genera, including Afroaeschna , Andaeschna , Pinheyschna , Rhionaeschna , and Zosteraeschna . [4]
The genus Aeshna includes these species: [4]
The Aeshnidae, also called aeshnids, hawkers, or darners, is a family of dragonflies. The family includes the largest dragonflies found in North America and Europe and among the largest dragonflies on the planet.

Aeshna williamsoniana, Williamson's darner, is a species of dragonfly in the family Aeshnidae. It is found in Belize, Costa Rica, Guatemala, Mexico, Panama, and possibly Honduras. Its natural habitats are subtropical or tropical moist montane forests and rivers. It is threatened by habitat loss.
Anaciaeschna is a genus of dragonflies in the family Aeshnidae. Species of Anaciaeschna are found in Africa, Asia and Australia.
The blue-spotted hawker is the only known species of dragonfly of the genus Adversaeschna in the family Aeshnidae.
Aeshna canadensis, the Canada darner, is a species of dragonfly in the family Aeshnidae. It is common throughout southern Canada and the northern United States.
Anax is a genus of dragonflies in the family Aeshnidae. It includes species such as the emperor dragonfly, Anax imperator.
Triacanthagyna is a genus of dragonflies in the family Aeshnidae. The species have large eyes and broad wings. The females have three prominent spines under the last abdominal segment which gives the genus its name. They are commonly known as three-spined darners.
The paddle-tailed darner is a species of dragonfly in the family Aeshnidae. It is common throughout western Canada and United States. This species is named after its distinctive paddle-shaped appendages. It lives in many habitats, particularly lakes, ponds, and slow streams, usually with dense shore vegetation. Aeshna palmata was scientifically described for the first time in 1856 by Hermann Hagen.
Neuraeschna is a genus of dragonflies in the family Aeshnidae. Its species are found from Peru and Brazil up through Honduras.

Rhionaeschna californica, the California darner, is a species of darner in the dragonfly family Aeshnidae. It is found in Central America and North America. And prefers habitats like lakes, ponds, marshes and stream pools with edge vegetation including many with alkaline water conditions Larvae sustain themselves on a diet of aquatic insects,very small fish and tadpoles.
