The emperor dragonfly or blue emperor is a large species of hawker dragonfly of the family Aeshnidae. It is the bulkiest dragonfly in most of Europe, including the United Kingdom, although exceeded in some areas by other species.
Coenagrionidae or are a family of damselflies, also known as pond damselfies, in the order Odonata and the suborder Zygoptera. The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common. More than 1,300 species are in this family, making it the largest damselfly family. The family Coenagrionidae has six subfamilies: Agriocnemidinae, Argiinae, Coenagrioninae, Ischnurinae, Leptobasinae, and Pseudagrioninae.
Coryphagrion grandis is a species of damselfly found in coastal forests and on the lower slopes of the Eastern Arc Mountains in Kenya, Tanzania and Mozambique. Its monotypic genus Coryphagrion is considered as the only member of the family Coryphagrionidae. It was once placed within the family Pseudostigmatidae, whose other members are all Neotropical, but further studies showed this family was paraphyletic.
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.
The Pseudostigmatidae are a family of tropical damselflies, known as helicopter damselflies, giant damselflies, or forest giants. The family includes the largest of all damselfly species. They specialize in preying on web-building spiders, and breed in phytotelmata, the small bodies of water held by plants such as bromeliads.
Megaloprepus caerulatus, also known as the blue-winged helicopter, is a forest giant damselfly of the family Coenagrionidae. Forest giant damselflies were previously recognized as their own family, Pseudostigmatidae. M. caerulatus is found in wet and moist forests in Central and South America. It has the greatest wingspan of any living damselfly or dragonfly, up to 19 centimetres (7.5 in) in the largest males. Its large size and the markings on its wings make it a conspicuous species; a hovering Megaloprepus has been described as a "pulsating blue-and-white beacon".
Coenagrion is a genus of damselflies in the family Coenagrionidae, commonly called the Eurasian Bluets. Species of Coenagrion are generally medium-sized, brightly coloured damselflies.
Hetaerina is a genus of damselflies in the family Calopterygidae. They are commonly known as rubyspots because of the deep red wing bases of the males. The name is from Ancient Greek: ἑταίρα (hetaira), courtesan. H. rudis, the Guatemalan rubyspot, is considered vulnerable on the IUCN Red Data List.
Mecistogaster is a genus of large Neotropical damselflies in the family Coenagrionidae, commonly known as helicopter damsels. There are eleven species distributed from Mexico to Argentina.
Neoneura is a genus of damselfly in the threadtail family Coenagrionidae. They are found in the Neotropics, from Cuba and Texas to Argentina.
Prodasineura, the Asian threadtails, is a genus of damselflies in the family Platycnemididae. All the Afrotropical species formerly in this genus are now placed in Elattoneura, the African threadtails. Dijkstra et al. (2014) moved the genus from Protoneuridae to Platycnemididae based on molecular phylogenetic research.
Pseudagrion is the largest genus of damselfly in the family Coenagrionidae, with over 140 species. Its range includes most of Africa, much of Asia, and Australia. Africa holds most of the diversity with almost 100 species. It has occupied most of the freshwater habitats in its range, and dominates damselfly communities in habitats as different as desert pools, equatorial rainforests and montane streams.
Trithemis is a genus of dragonflies in the family Libellulidae. They are commonly known as dropwings. There are over 40 species, mainly from Africa; two are endemic to Madagascar, and five can be found in Asia. They are found in a wide variety of habitats; some species being adapted to permanent streams in forests, and others being capable of breeding in temporary pools in deserts.
The Protoneuridae are a family of damselflies. Most species are commonly known as threadtails, while others are commonly known as bambootails.
Calopteryx haemorrhoidalis is a species of damselfly in the family Calopterygidae known by the common names copper demoiselle and Mediterranean demoiselle.
Euphaeidae, sometimes incorrectly named Epallagidae and commonly called gossamerwings, is a family of damselflies in the odonate superfamily Calopterygoidea. The family is small, consisting of around 78 species living species in nine genera occurring in the Palearctic, Australasia, and Asia. The family contains two subfamilies, Euphaeinae, encompassing all the living species and a single fossil genus, and the extinct Eodichromatinae, encompassing fossil genera from the Eocene to late Oligocene. Euphaeid species are large and mostly metallic-coloured, looking similar to species of damselflies in the family Calopterygidae.
Prodasineura verticalis is a damselfly in the family Platycnemididae. It is commonly known as the red-striped black bambootail or black bambootail.
Platysticta is a genus of shadowdamsel in the damselfly family Platystictidae. There are about nine described species in Platysticta.
Pseudostigma is a genus of damselflies in the family Coenagrionidae. There are at least two described species in Pseudostigma.
The giant hawker or the gigantic riverhawker, is a species of dragonfly in the family Aeshnidae. It is found throughout Sundaland, having been recorded on Thailand, Peninsular Malaysia, Singapore, Sumatra, and Borneo. It is the type species for the genus Tetracanthagyna.
