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 ...

Azure Hawker
The azure hawker (''Aeshna caerulea'') is one of the smaller species of hawker dragonflies, (family Aeshnidae). The flight period is from late May to August It is about 62 mm long. Both sexes have azure blue spots on each abdominal segment and the thorax also has azure markings. The markings on the male are brighter and more conspicuous than in the female. The female also has a brown colour form. This species flies in sunshine, and will also bask on stones or tree trunks. It shelters in heather or similar low vegetation in dull weather. Unique to this species is that the blue of the male pales to a more grey colour at lower temperatures. The species is widespread in the Eurasian polar region. In Great Britain, the azure hawker occurs only in Scotland Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by t ...

Hairy Dragonfly
''Brachytron'' is a monotypic genus of European dragonfly of the family Aeshnidae containing the hairy dragonfly (''Brachytron pratense''), also known as the hairy hawker or spring hawker.

Aeshnidae
The Aeshnidae, also called aeshnids, hawkers, or darners, is a family of dragonflies. The family includes the largest dragonflies found in North America and Europe Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia ... and among the largest dragonflies on the planet. Description Common worldwide or nearly worldwide genera are ''Aeshna'' and ''Anax (dragonfly), Anax''. The African ''Anax tristis'' has a wingspan over 125 mm, making it one of the world's largest known dragonflies. There are 41 North American species in 11 genera in this family. Most European species belong to ''Aeshna''. Their American name "darner" stems from the female abdomens looking like a sewing needle, as they cut into plant stem when they lay their eggs through the ovipositor. The dragonflies mate in fligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Green Club-tailed Dragonfly
''Ophiogomphus cecilia'', the green snaketail, green gomphid, or green club-tailed dragonfly, is a species of dragonfly in the family Gomphidae. Description The only snaketail in Europe; resembles a large clubtail in general coloration and river habitat, but the 'front-end' is vivid apple green in mature individuals and the male appendages are short. It is the largest of the Gomphidae apart from Bladetail'','' with green eyes and 'face, and green thorax with thin black lines on top and side, the latter similar to those on Yellow Clubtail and Western Clubtail'';'' at the base of abdomen the green is extending to S2, the rest of the abdomen has a discontinuous yellow pattern to S 10, generally broader than on clubtails and those on S3-7 more triangular in shape, and moderately clubbed at S8-9. The legs are extensively yellow. Males appendages are short and yellowish. Female yellow markings on the abdomen are broader than on males. It shows two tiny 'crests' on the back of the he ...

Club-tailed Dragonfly
The Gomphidae are a family of dragonflies commonly referred to as clubtails or club-tailed dragonflies. The family contains about 90 genera and 900 species found across North and South America, Europe, Asia, and Australia. The name refers to the club-like widening of the end of the abdomen (abdominal segments 7 through 9). However, this club is usually less pronounced in females and is entirely absent in some species. Etymology The name may be derived from Latin ''gomphus'' or ''gond'' meaning "hinge". Characteristics Clubtails have small, widely separated compound eyes, a trait they share with the Petaluridae and with damselflies. The eyes are blue, turquoise, or green. The thorax in most species is pale with dark stripes, and the pattern of the stripes is often diagnostic. They lack the bright metallic colors of many dragonfly groups and are mostly cryptically colored to avoid detection and little difference between the sexes is seen. Adults are usually from in length; there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-legged Dragonfly
The river clubtail or yellow-legged dragonfly (''Gomphus flavipes'') is a species of dragonfly in the family Gomphidae. It is found in Europe. Its natural habitat are rivers and large streams. The dragonfly flies from June to September depending on the location. Geographical distribution ''G. flavipes'' is a European species. It has the biggest geographical range among the European Gomphid species, occurring from France to eastern Siberia. The species has a very patchy occurrence in Central Europe and has become rare in Western Europe. The southernmost occurrence is known from Greece. In Southern Europe ''G. flavipes'' is replaced by other Gomphid species. However, the exact geographical range of the species is still unclear. Habitat ''G. flavipes'' lives along the middle and lower reaches of slow flowing medium-sized and big rivers The species prefers riverbed with mud, clay, loam or fine sand as soil, since larvae develop buried in the soil, but avoids areas with decompositi ...
