Aeshna,[2] the hawkers or mosaic darners, is a genus of dragonflies in the family Aeshnidae. Species within this genus are generally known as "hawkers" in the Old World,[3] or "darners" in the New World.

Description

[edit]

These are relatively large dragonflies; the European species measure 59–83 mm body length. Their thoraces and abdomens are brown, with blue, green, or yellow stripes or spots on the thorax, and yellow, blue, or green spots on the abdomen; the size and shape of these spots is important in identification of the different species.[3]

A study in 2003 demonstrated that the Holarctic and Neotropical species placed in this genus formed two clades that did not share a common ancestor, and proposed the latter be transferred to a separate genus Rhionaeschna.[4]

The name Aeshna was coined by the Danish entomologist Fabricius in 1775, with the type species being the brown hawker Aeshna grandis.[5] The name may have resulted from a printer's error in spelling the Greek Aechma, "a spear".[6] The spelling "Aeschna" has been used intermittently, but was rejected by the ICZN in 1911 as an unjustified emendation of the original name Aeshna.[7] However, derived genus names (such as Rhionaeschna) retain the 'sch' spelling, as this is how they were first cited.

Species

[edit]

Many species formerly included in Aeshna have been split into other genera, including Afroaeschna, Andaeschna, Isoaeschna, Pinheyschna, Rhionaeschna, and Zosteraeschna.[8] The former Aeshna isoceles is also split out, as Isoaeschna isoceles.[5]

The genus Aeshna includes these species:[8]

Fossil species

[edit]

Note that many fossil species in the genus were named at a time when many extant species now included in other genera were included in Aeshna.[8] The list of valid fossil species is based on Nel et al. (2022), with species of uncertain validity noted:[14][15]
