Golden-ringed Dragonfly
The golden-ringed dragonfly (''Cordulegaster boltonii'') is a large, striking dragonfly and the longest British species, the only member of its genus to be found in the United Kingdom. Identification They are easily identified by their distinctive black and yellow stripes, which no other dragonfly in the United Kingdom has. A very large species, males average 74 mm and the larger females 84 mm. Wingspan is up to 101 mm. Larvae The female lays the eggs in shallow water. The hairy larvae live at the bottom of the water and are well camouflaged amongst the silt. They emerge after about 2–5 years, and usually under the cover of darkness. Behaviour They are often seen flying leisurely over mountain streams or a river; they also occasionally show up at a pond. They are also typically seen flying over heath land. Their bright yellow and black stripes make them easy to identify, even from a fair distance away. They feed mainly on insects ranging from small prey such as ...

Rockingham Forest
Rockingham Forest is a former royal hunting forest in the county of Northamptonshire, England. It is an area of some lying between the River Welland and River Nene and the towns of Stamford and Kettering. It has a rich and varied landscape, with farmland, open pasture, pockets of woodland and villages built from local stone. History The forest was named after the village of Rockingham, where the castle was a royal retreat. The boundaries were marked by the River Nene on the eastern side and on the western side what is now the A508 road from Market Harborough to Northampton. Over the years the forest shrank, and today only a patchwork of the north-eastern forest remains. The bulk of the remaining forest is located within a square, of which the corners are Corby, Kettering, Thrapston and Oundle. The area became a royal hunting ground for King William I after the Norman conquest. The term ''forest'' represented an area of legal jurisdiction and remained so until the 19th centur ...

Edward Donovan
Edward Donovan (1768 – 1 February 1837) was an Anglo-Irish writer, natural history illustrator, and amateur zoologist. He did not travel, but collected, described and illustrated many species based on the collections of other naturalists. His many books were successful in his time. He died penniless in 1837 leaving a large family destitute. Personal life Almost nothing is known about Donovan's family background, education or early life, although he is known to have been born in Cork, Ireland, and was originally surnamed O'Donovan. He is presumed to have had some independent wealth. His health declined in later years and he died penniless at his home in John Street in 1837 leaving a large family destitute. Biography Aged 21, he moved to London. He was an avid collector of natural history specimens purchased mainly at auctions of specimens from voyages of exploration. He was a fellow of the Linnean Society and the Wernerian Society which gave him access to the best collecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

British Dragonfly Society
The British Dragonfly Society is a conservation organisation in the United Kingdom. It was founded in 1983 and its aims are to promote and to encourage the study and conservation of dragonflies and damselflies and their natural habitats, especially in the United Kingdom. The Society runs the Dragonfly Recording Network (DRN) to collect Odonata records in the UK. It also promotes a range of research and conservation projects. The British Dragonfly Society is a registered charity, number 800196. See also *Odonata *List of British dragonflies There are 57 recorded species of Odonata in Britain, made up of 21 damselflies (suborder Zygoptera) and 36 dragonflies (suborder Anisoptera).

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

ARKive
ARKive was a global initiative with the mission of "promoting the conservation of the world's threatened species, through the power of wildlife imagery", which it did by locating and gathering films, photographs and audio recordings of the world's species into a centralised digital archive. Its priority was the completion of audio-visual profiles for the c. 17,000 species on the IUCN Red List of Threatened Species. The project was an initiative of Wildscreen, a UK-registered educational charity, based in Bristol. The technical platform was created by Hewlett-Packard, as part of the HP Labs' Digital Media Systems research programme. ARKive had the backing of leading conservation organisations, including BirdLife International, Conservation International, International Union for Conservation of Nature (IUCN), the United Nations' World Conservation Monitoring Centre (UNEP-WCMC), and the World Wide Fund for Nature (WWF), as well as leading academic and research institutions, such ...

List Of British Dragonflies
There are 57 recorded species of Odonata in Britain, made up of 21 damselflies (suborder Zygoptera) and 36 dragonflies (suborder Anisoptera). Of these, 42 species (17 damselflies and 25 dragonflies) are resident breeders, and the remainder are either extinct species, or vagrants - in respect of the latter, this list follows the decisions of the Odonata Records Committee. Some of these rare species have not been seen since the 19th Century; however, the British Odonata list is also currently undergoing a period of unprecedented change, as new species are being discovered for the first time, some going on to become breeding species. This list is based on the following principal references: * Merritt, R., N. W. Moore and B. C. Eversham (1996), '' Atlas of the dragonflies of Britain and Ireland'', HMSO () * Parr, A. J. (1996), Dragonfly movement and migration in Britain and Ireland, ''Journal of the British Dragonfly Society'' Vol. 12 No. 2 pp. 33–50 * Parr, Adrian (2000a), ...

Cordulegastridae
The Cordulegastridae are a family of Odonata (dragonflies) from the suborder Anisoptera. They are commonly known as spiketails. Some vernacular names for the species of this family are biddie and flying adder. They have large, brown or black bodies with yellow markings, and narrow unpatterned wings. Their bright eyes touch at a single point, and they can be found along small, clear, woodland streams, flying slowly 30 to 70 cm above the water. When disturbed, however, they can fly very rapidly. They usually hunt high in forest vegetation, and prefer to capture prey resting on leaves or branches (known as gleaning). The Cordulegastridae usually lay their eggs in the sand in shallow water, the female hovering just above the water with her body in a vertical position, and making repeated dips into the water with her abdomen. The family is distributed worldwide; all eight species in North America belong to the genus '' Cordulegaster''. The name Cordulegastridae comes from the G ...
