The skimmers or perchers and their relatives form the Libellulidae, the largest dragonfly family in the world. It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded (as Silsby does), there still remains a family of over 1000 species. With nearly worldwide distribution, these are almost certainly the most often seen of all dragonflies.

Dragonfly Infraorder of insects with long strong bodies and two pairs of wings

A dragonfly is an insect belonging to the order Odonata, infraorder Anisoptera. Adult dragonflies are characterized by large, multifaceted eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Dragonflies can be mistaken for the related group, damselflies (Zygoptera), which are similar in structure, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold the wings folded at rest, along or above the abdomen. Dragonflies are agile fliers, while damselflies have a weaker, fluttery flight. 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.

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

The insect family Corduliidae contains the emerald dragonflies or green-eyed skimmers. These dragonflies are usually black or dark brown with areas of metallic green or yellow, and most of them have large, emerald-green eyes. The larvae are black, hairy-looking, and usually semiaquatic. Members of this family include the baskettails, emeralds, river cruisers, sundragons, shadowdragons, and boghaunters. They are not uncommon and are found nearly worldwide, but some individual species are quite rare. Hine's emerald dragonfly, for example, is an endangered species in the United States.

The genus Libellula is mostly New World, but also has one of the few endangered odonates from Japan: Libellula angelina . Many of the members of this genus are brightly colored or have banded wings. The related genus Plathemis includes the whitetails. The genus Celithemis contains several brightly marked species in the southern United States. Members of the genus Sympetrum are called darters (or meadowhawks in North America) and are found throughout most of the world, except Australia. Several Southern Hemisphere species in the genera Trithemis and Zenithoptera are especially beautiful. Other common genera include Tramea and Pantala .

<i>Libellula</i> genus of insects

Libellula is a genus of dragonflies, commonly called skimmers, in the family Libellulidae, distributed throughout the temperate zone of the Northern Hemisphere. Most species are found in the United States, where they are the best-known large dragonflies, often seen flying over freshwater ponds in summer. Many have showy wing patterns.

New World Collectively, the Americas and Oceania

The New World is one of the names used for the majority of Earth's Western Hemisphere, specifically the Americas, and Oceania.

Japan Country in East Asia

Japan is an island country in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian continent and stretches from the Sea of Okhotsk in the north to the East China Sea and the Philippine Sea in the south.

The libellulids have stout-bodied larvae with the lower lip or labium developed into a mask over the lower part of the face.

Larva juvenile form of distinct animals before metamorphosis

A larva is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle.

Etymology

The family name may have been derived from the Latin libella which means "booklet".

Genera

The Libelluidae contain these genera:

<i>Acisoma</i> genus of insects

Acisoma is a small genus of dragonflies in the family Libellulidae. It contains six species:

Aethiothemis is a small genus of dragonflies in the family Libellulidae.

<i>Aethriamanta</i> genus of insects

Aethriamanta is a genus of dragonflies in the family Libellulidae. Species of Aethriamanta are found in Madagascar, through Southeast Asia, Indonesia, New Guinea and northern Australia.

<i>Orthetrum sabina</i> species of insect

Orthetrum sabina, the slender skimmer or green marsh hawk, is a species of dragonfly in the family Libellulidae. It is widespread, being found from south-eastern Europe and North Africa to Japan and south to Australia and Micronesia.

<i>Libellula depressa</i> species of insect

Libellula depressa, the broad-bodied chaser or broad-bodied darter, is one of the most common dragonflies in Europe and central Asia. It is very distinctive with a very broad flattened abdomen, four wing patches and, in the male, the abdomen becomes pruinose blue.

<i>Trithemis kirbyi</i> species of insect

Trithemis kirbyi, also known as the orange-winged dropwing, scarlet rock glider, or Kirby's dropwing, is a species of dragonfly in the family Libellulidae.

<i>Diplacodes</i> genus of insects

Diplacodes is a genus of dragonflies in the Libellulidae family. They are commonly known as perchers. Their colours range from the totally black body of the African Diplacodes lefebvrii, the lovely pale blue of India's Diplacodes trivialis, to the intense red of the Asian–Australian Diplacodes haematodes.

<i>Sympetrum</i> genus of insects

Sympetrum is a genus of small to medium-sized skimmer dragonflies, known as darters in the UK and as meadowhawks in North America. The more than 50 species predominantly live in the temperate zone of the Northern Hemisphere; no Sympetrum species is native to Australia.

<i>Lestes</i> genus of insects

<i>Macromia</i> genus of insects

Macromia is a genus of large dragonflies in the family Macromiidae. They are commonly known as river cruisers from their habit of cruising long distances along river banks.

They typically have colored bases to their otherwise translucent hindwings. In particular when they fly, this creates the impression of their carrying bags at the start of their abdomens. They are known commonly as saddlebags or saddlebags gliders.

<i>Zygonyx</i> genus of insects
