The petaltails of the family Petaluridae are among the most ancient of the extant true dragonflies (infraorder Anisoptera), [2] having fossil members from as early as the Jurassic, over 150 million years ago. A 2024 molecular phylogeny found that the petaltails comprise two clades, a Gondwanan clade and a Laurasian clade. Their divergence time was estimated at 160 million years ago. [3]
Modern petalurids include only 11 species, one of which, the Australian Petalura ingentissima , is by some measurements the largest of living dragonflies, having a wingspan of up to about 160 mm (6.3 in) and a body length of about 125 mm (4.9 in) ( Tetracanthagyna plagiata of another family can match or exceed its wingspan). Another large Australian species is Petalura gigantea , commonly known as the giant dragonfly. In the United States, two species are found, Tanypteryx hageni in the west and Tachopteryx thoreyi in the east. The larvae live primarily in stream banks, mostly in burrows, but the larvae of the eastern US species, Tachopteryx thoreyi, the gray petaltail, live in depressions under wet leaves. [4] The semiaquatic habitat of the larvae makes the petaltails unique in the modern dragonfly families.
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies. The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies are usually more slender with eyes placed apart and wings folded together along body at rest. Adult odonates can land and perch, but rarely walk.
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 insect family Macromiidae contains the dragonfly species known as cruisers or skimmers. They tend to fly over bodies of water straight down the middle. They are similar to Aeshnidae in size, but the eyes are green and just barely meet at the top of the head.
The Gomphidae are a family of dragonflies commonly referred to as clubtails or club-tailed dragonflies. The family contains about 90 genera and 900 species found across North and South America, Europe, Asia, Australia, and Africa. The name refers to the club-like widening of the end of the abdomen. However, this club is usually less pronounced in females and is entirely absent in some species.
The Platycnemididae are a family of damselflies. They are known commonly as white-legged damselflies. There are over 400 species native to the Old World. The family is divided into several subfamilies.
Petalura pulcherrima is a species of Australian dragonfly in the family Petaluridae, commonly known as a beautiful petaltail. It is a very large and slender dragonfly, mostly black or dark brown with yellow markings and its eyes widely separated on top of its head. It has clear wings and a very long, narrow pterostigma.
Petalura is a genus of very large dragonflies in the family Petaluridae. Species of Petalura are brown or black with yellow markings and usually clear wings. The anal appendages of the males are broad and leaf-like giving them their common name of petaltails. They are endemic to south-western and eastern Australia.
Chlorocyphidae is a family of damselflies, commonly known as jewels. These are colorful species native to the Old World tropics, where they occur along forest streams. They are most diverse in Southeast Asia.
Platystictidae is a family of damselflies, commonly known as shadowdamsels. They look very similar to the threadtail damselfly family (Protoneuridae). They can mostly be found throughout Asia, Central America, and South America.
The Synthemistidae are the family of dragonflies commonly known as tigertails, or sometimes called southern emeralds. This family is part of the superfamily Libelluloidea.
Petalura litorea, commonly known as the coastal petaltail, is an endangered Australian species of dragonfly from the family Petaluridae.
Coenagrionoidea is a superfamily of closed wing damselflies of the order Odonata found worldwide.
Aeshnoidea is a superfamily of dragonflies that contains two extant families, Aeshnidae and Austropetaliidae.
Cordulegastroidea is a superfamily of dragonflies that contains three families.
Libelluloidea is a superfamily of dragonflies.
Cordulephya is a genus of dragonflies assigned to the superfamily Libelluloidea, and endemic to eastern Australia. The species are small to tiny in size, coloured black, or purplish-black, with yellowish markings. Unusually for Anisoptera, these dragonflies rest with their wings folded above their body in a similar manner to many species of damselfly. They are commonly known as shutwings.
Cordulephyidae was formerly considered a distinct family of dragonflies occurring in Africa and Australia. Recent taxonomic revisions have classified the species previously placed in Cordulephyidae to now be within the superfamily Libelluloidea.
Austrocorduliidae was formerly considered a family of dragonflies occurring in South Africa and Australia. Recent taxonomic revisions have classified the species previously placed in Austrocorduliidae to now be within the superfamily Libelluloidea.
Gomphomacromiidae was formerly considered a distinct family of dragonflies occurring in Chile and Australia. Recent taxonomic revisions have classified the species previously placed in Gomphomacromiidae to now be within the superfamily Libelluloidea.
Calopterygoidea is a superfamily of damselflies in the order Odonata.
