Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica.
The banded demoiselle is a species of damselfly belonging to the family Calopterygidae. It is often found along slow-flowing streams and rivers. It is a Eurasian species occurring from the Atlantic coast eastwards to Lake Baikal and northwestern China.
The beautiful demoiselle is a European damselfly belonging to the family Calopterygidae. It is often found along fast-flowing waters where it is most at home.
The Mauritius fody is a rare species of bird in the weaver family. It is endemic to the island of Mauritius. It is classified by BirdLife International as being endangered. It is also on the United States' Endangered Species List with an endangered status.
Papilio homerus, commonly known as the Homerus swallowtail or Jamaican swallowtail, is the largest butterfly species in the Western Hemisphere. The species is endangered and faces a potentially bleak future. Only two small populations of the Homerus swallowtail remain in a fraction of their original environment. It is endemic to Jamaica where the butterfly simultaneously serves as an icon of national pride and a need for conservation efforts. Over the past half century, the Jamaican swallowtail has been featured on various postal stamps and the Jamaican $1000 bill. In the face of rapid habitat destruction from human disruption and illegal collecting, the Jamaican swallowtail is listed on the Threatened Swallowtail Butterflies of the World by the International Union for Conservation of Nature and is protected under international and national level legislation.
The Rodrigues fody is a rare species of bird in the weaver family. It is endemic to Rodrigues, an island of Mauritius. It is classified by BirdLife International as being vulnerable. It is also on the United States' Endangered Species List with an endangered status.
The pygmy shrew tenrec is a species of placental mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. While it is not endangered, its population is slowly declining as it is threatened by habitat loss. This is of concern, though does not yet merit a higher protection level.
The Tana River red colobus, also called the eastern red colobus, is a highly endangered species of primate in the family Cercopithecidae. It is endemic to a narrow zone of gallery forest near the Tana River in southeastern Kenya.
The long-tailed forest shrew, or long-tailed mouse shrew, is a species of mammal in the family Soricidae. It is endemic to South Africa, where its natural habitats are Mediterranean-type shrubby vegetation and swamps.
Amanipodagrion gilliesi is a species of damselfly. Its monotypic genus Amanipodagrion was formerly in the subfamily Argiolestinae of the flatwing damselfly family (Megapodagrionidae). As a result of molecular phylogenetic studies by Dijkstra et al. in 2013, the genus Amanipodagrion is now considered "incertae sedis", without an assigned family but within the superfamily Calopterygoidea.
Coenagrion mercuriale, the southern damselfly, is a species of damselfly in the family Coenagrionidae. It is found in Algeria, Austria, Belgium, France, Germany, Italy, Liechtenstein, Luxembourg, Morocco, the Netherlands, Portugal, Romania, Slovakia, Slovenia, Spain, Switzerland, Tunisia, and the United Kingdom. Its natural habitats are rivers and freshwater springs. It is threatened by habitat loss.
Ischnura gemina is a species of damselfly in the family Coenagrionidae known by the common name San Francisco forktail. It is endemic to the San Francisco Bay Area in California in the United States. This uncommon insect has a total range of less than 500 square miles in the Bay Area, occurring only in greater San Francisco and parts of San Mateo and Marin Counties. This species is "one of the rarest Odonates in the United States."
Megalagrion nesiotes is a species of damselfly in the family Coenagrionidae. Its common name is flying earwig Hawaiian damselfly. It is endemic to Hawaiʻi, where it is known from only one location on the island of Maui. It is extirpated from the island of Hawaii. This insect was federally listed as an endangered species of the United States in 2010.
Megalagrion pacificum is a species of damselfly in the family Coenagrionidae. It is endemic to rivers and freshwater marshes in Hawaiʻi, especially the island of Molokaʻi. It is threatened by habitat loss. This insect was federally listed as an endangered species of the United States in 2010.
Risiocnemis seidenschwarzi is a species of damselfly in the family Platycnemididae and the only known species in the genus Risiocnemis. It is endemic to the Philippines. It can only be found in a small river area in one of the last forests in Central Cebu, which is threatened by habitat loss, illegal logging, and water pollution. The survival of the species is believed to rely solely only the continued conservation of the river where it lives and breeds. There are no conservation programs yet to be administered in the area where it lives. It is the most endangered insect species in the whole Philippine archipelago. It is one of the 2012 World's 100 Most Threatened Species, which was compiled by IUCN and the Zoological Society of London.
The Roloway monkey is an endangered species of Old World monkey endemic to tropical West Africa. It was previously considered a subspecies of the Diana monkey. The species is classified as Critically Endangered due to habitat loss and their continued hunting because of the bushmeat trade. The Roloway monkey is mainly an arboreal species, for the most part inhabiting forests in Ghana and some reserves in South-Eastern Côte-D'Ivoire. More specifically, studies have shown that the C. diana roloway is primarily concentrated in the Tanoé forest of the Côte-D'Ivoire because of their heavy threats to extinction and lack of habitat. It is still difficult to gather data on wild subjects, as they have low populations in a vast forest, but they are a unique and vanishing species.
Pseudochazara cingovskii, the Macedonian grayling, is a species of butterfly in the family Nymphalidae. It is found only in the North Macedonian village of Pletvar. The males are a little smaller than the females.
Proischnura polychromatica, the mauve bluet, is a small species of damselfly in the family Coenagrionidae. It is endemic to a small area of Cape Province in South Africa. The adult male has a mauve sheen to its dark-coloured body, a bronze-green thorax striped with mauve, and a pale brown abdomen with a bronze-green dorsal stripe. The female is mainly pale brown. The natural habitat of this damselfly is transient pools in stream beds with floating vegetation, especially sedges. Although previously more widespread, it is now known from a single location where it is threatened by the encroachment of cattle and the loss of suitable habitat. For these reasons, the International Union for Conservation of Nature has rated it as "endangered".
Calopteryx hyalina is a species of broad-winged damselfly in the family Calopterygidae.
