Darner
Aeshnidae, also called aeshnids, hawkers, or darners, is a family of dragonflies, found nearly worldwide, with more than 50 genera and over 450 species. The family includes some of the largest dragonflies. Description Common worldwide or nearly worldwide genera are ''Aeshna'' and ''Anax''. ''Anax'' includes some of the largest dragonflies, including the North American '' A. walsinghami'', Hawaiian '' A. strenuus'', European '' A. imperator'' and '' A. immaculifrons'', and African '' A. tristis'', but these are all exceeded by another member of the family, the Asian ''Tetracanthagyna plagiata'', which by wingspan and weight is the world's largest dragonfly. There are 41 North American species in 11 genera in this family. Most European species belong to ''Aeshna''. Their American name "darner" stems from the female abdomens looking like a sewing needle, as they cut into plant stem when they lay their eggs through the ovipositor. The dragonflies mate in flight. The eggs are deposi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeshna
''Aeshna'', or the mosaic darners, is a genus of dragonfly, dragonflies from the family Aeshnidae. Species within this genus are generally known as "hawkers" (Old World) or "darners" (New World). Description 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 Johan Christian Fabricius, Fabricius in the 18th century. The name may have resulted from a printer's error in spelling the Greek ''Aechma'', "a spear". 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 a ...

Dragonflies
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterised by a pair of large, multifaceted, compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural coloration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, alo ...

Tasmanian Darner
The Tasmanian darner, (''Austroaeschna tasmanica''), is a species of large dragonfly in the family Aeshnidae, which includes some of the world's largest dragonflies. It is found in Tasmania, Australia. The species was first described by Robert Tillyard in 1916 and inhabits streams and rivers. Also referred to as "hawkers", the name "darner" derives from the fact that the female abdomen looks like a sewing needle, as it cuts into a plant stem when the female dragonfly lays her eggs through her ovipositor The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typica ....

Giant Hawaiian Darner
The giant Hawaiian darner (''Anax strenuus''), also known as the giant Hawaiian dragonfly or pinao, is a species of dragonfly in the family Aeshnidae. It is one of two species of dragonfly that is endemic to the Hawaiian Islands (the other is '' Nesogonia blackburni''). It is found near streams and wetlands on all islands of the archipelago and it has a wide altitude range, but is particularly common at higher elevations. This species is one the world's largest living dragonflies and the largest in the United States. It typically has a wingspan of , but has been verified to reach up to ; reports of considerably greater sizes are unverified and highly questionable. The only other member of the genus ''Anax'' in Hawaii is the closely related green darner (''A. junius''), but it is considerably smaller, mainly found in lowlands in Hawaii, and also found in Asia and North America.

Antiquiala
''Antiquiala'' is an extinct anisopteran genus in the dragonfly family Aeshnidae with a single described species, ''Antiquiala snyderae''. The species is solely known from the Early Eocene sediments exposed in the northeast of the U.S. state of Washington. The single fossil known was found at the "Boot Hill" site in Republic and added to the Stonerose Interpretive Center research collection before being officially described in 2019. The genus is thought to be most similar to another early Eocene genus, '' Huncoaeshna'', which was recovered from the Laguna del Hunco Formation in South America. Distribution The lone ''Antiquiala snyderae'' fossil was recovered from a single site in the Eocene Okanagan Highlands of Central British Columbia and northeast central Washington state. The described specimen is from the Klondike Mountain Formation in Northern Ferry County, Washington, being recovered from the "Boot Hill" site B4131 in Republic, Washington.
