Petaluridae
The petaltails of the family Petaluridae are apparently the most ancient of the extant true dragonflies (infraorder Anisoptera), having fossil members from as early as the Jurassic (over 150 million years ago). Modern petalurids include only 11 species, one of which, the Australian ''Petalura ingentissima'', is the largest of living dragonflies, having a wingspan of up to 160 mm and a body length of over 100 mm. Other Australian species include ''Petalura gigantea'' (commonly known as the giant dragonfly). In the United States, two species are found, one on either coast. The larvae live primarily in stream banks, mostly in burrows, but the larvae of the eastern US species, ''Tachopteryx thoreyi ''Tachopteryx thoreyi'', commonly known as the gray petaltail and Thorey's grayback, is a species of dragonfly.

Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized 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 colouration, 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, along or ...

Phenes
''Phenes raptor'' is a species of dragonfly from Chile and other parts of South America. Larvae specimen have been collected along the Malleco River and additionally from a farm mill, whereas an adult specimen has been collected from additional sites in Chile. ''Phenes raptor'' is a predator, and it is the physically largest dragonfly in Chile. ''Phenes raptor'' is the only member of its genus. Body The body of ''Phenes raptor'' is part of a group of Odonata with similar features, nicknamed the ''Odonata of Chile''. These measure approximately 35–52 mm for its hindwings. They tend to have thin yet stubby bodies, tinted lightly yellow. Their faces are black, with a thin crossbar above its mouth, while its eyes are set widely apart, and the eyes are eventually joined by a point or dot near the center of its face. The male ''Phenes raptor'' has small anal appendages (more commonly known as tails), with three to four 4- celled triangles, which includes a small notch towards t ...

Tachopteryx Thoreyi
''Tachopteryx thoreyi'', commonly known as the gray petaltail and Thorey's grayback, is a species of dragonfly. It is native to the East Coast of the United States as far north as New York, as far south as Florida, and as far west as Texas. This species is the only member of the monotypic genus ''Tachopteryx''. The gray petaltail lives in highlands, woodlands, and deciduous forests with permanent seeps, often indicated by the presence of skunk cabbage and ferns. The gray petaltail is primarily gray and black in color; the thorax is usually entirely gray, while the abdomen The abdomen (colloquially called the belly, tummy, midriff, tucky or stomach) is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates.

Petalura Gigantea
''Petalura gigantea'', the giant dragonfly or south-eastern petaltail, is one of the world's largest dragonflies, with the males having an abdomen 6-7.5 cm long and a wingspan up to 11 cm, while females have an abdomen 8-9.5 cm long and a wingspan up to 12.5 cm. The giant dragonfly occurs along the east coast of NSW from the Victorian border to northern NSW, and is not found west of the Great Dividing Range. There are known occurrences in the Blue Mountains and Southern Highlands, in the Clarence River catchment, and on a few coastal swamps from north of Grafton to Nadgee in the south. It is unusual not only in size, but also in having predominantly terrestrial habits at the larval stage. The giant dragonfly is listed as endangered under the NSW Threatened Species Conservation Act. This listing was transferred to the equivalent schedules under the Biodiversity Conservation Act 2016 (NSW) from August 2017. ''Petalura gigantea'' is a species of dragonfly in th ...

Petalura Ingentissima
''Petalura ingentissima'', the giant petaltail, has been described as the world's largest dragonfly, with a wingspan of 160 mm. It is found in Queensland, Australia. Dr R.J. Tillyard described the giant petaltail in 1908. Its species name is derived from the Latin adjective ''ingens'' "huge". It is one of five species in the Australian genus ''Petalura''. A large heavily built dragonfly, the giant petaltail has a black body with some yellow markings. The female's wingspan can be 158–162 mm and body length 125 mm, the largest dragonfly species in overall dimensions although members of the genus ''Tetracanthagyna'' can have longer wings and ''Chlorogomphus papilio'' a larger wing area. Measuring 5.9-6.3 cm long, the larvae are unusual in that they live in burrows along the river margin and hunt passing prey.

Odonata Families
Odonata is an order of flying insects that includes the dragonflies and damselflies. Members of the group first appeared during the Triassic, though members of their total group, Odonatoptera, first appeared in Late Carboniferous. The two common groups are distinguished with dragonflies, placed in the suborder Epiprocta, usually being larger, with eyes together and wings up or out at rest, while damselflies, suborder Zygoptera, are usually smaller with eyes placed apart and wings along body at rest. All Odonata have aquatic larvae called naiads (nymphs), and all of them, larvae and adults, are carnivorous. The adults can land, but rarely walk. Their legs are specialised for catching prey. They are almost entirely insectivorous. Etymology and terminology Fabricius coined the term ''Odonata'' in 1793 from the Ancient Greek ( Ionic form of ) 'tooth'. One hypothesis is that it was because their maxillae are notably toothed. Most insects also have toothed mandibles. The wor ...
