List Of Dragonflies Of Menorca
Menorca is a small island in the Mediterranean Sea belonging to Spain. Along with Majorca, Ibiza, and Formentera it is part of the Balearic Islands. It has a population of approximately 88,000. It is located 39°47' to 40°00'N, 3°52' to 4°24'E. It is a dry island without many wetlands or river systems; many of the wetlands in Menorca were drained to provide agricultural land. Despite this dragonflies are abundant on Menorca and in summer any pool of water will be alive with them. The best months to see dragonflies are May to September. The taxonomy follows that of Dijkstra, K-D.B & Lewington, R. (2006).

Red Veined Darter 2
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the ...

Anax Imperator
The emperor dragonfly or blue emperor (''Anax imperator'') is a large species of hawker dragonfly of the family Aeshnidae, averaging in length. The generic name ''Anax'' is from the ancient Greek , "lord"; the specific epithet ''imperator'' is the Latin for "emperor", from ''imperare'', to command. Distribution This dragonfly has a wide distribution; it is found throughout Africa and through most of Europe, the Arabian Peninsula, and south-western and central Asia. Since 2000, its range has expanded in Europe, both northwards and to higher altitudes. Behaviour They frequently fly high up into the sky in search of prey, which includes butterflies, other Odonata and tadpoles; small prey is eaten while flying. They breed in a variety of aquatic habitats from large ponds to dikes, but they require a plentiful supply of vegetation in the water. The females lay the eggs into plants such as pondweed, and always lay alone. The larvae are very aggressive and are likely to influence the ...

Aeshna
''Aeshna'', or the mosaic darners, is a genus of dragonflies from the family Aeshnidae. Species within this genus are generally known as "hawkers" (Old World) or "darners" (New World). Description These are relatively large dragonflies. Their thoraces and abdomens are brown in color, with blue or yellow stripes or spots on the thorax, and yellow, blue or green spots on the abdomen. Natalia von Ellenrieder's 2003 paper demonstrated that the Holarctic and Neotropical species placed in this genus did not share a common ancestor, and proposed the latter be placed in the genus '' Rhionaeschna''. The name ''Aeshna'' was coined by the Danish entomologist Fabricius in the 18th century. The name may have resulted from a printer's error in spelling the Greek ''Aechma'', "a spear". The spelling ''Aeschna'' has been intermittently used over a period of time, but is now abandoned for the original name ''Aeshna''. However, derived genus names (such as '' Rhionaeschna'') retain the 'sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aeshna Isoceles
''Aeshna isoceles'' is a small hawker dragonfly that is found in Europe, mostly around the Mediterranean, and the lowlands of North Africa. Its common name in English is green-eyed hawker. In Britain it is a rare and local species and is known as the Norfolk hawker. It has a brown colour with green eyes and clear wings and also a yellow triangular mark on the second abdominal segment which gave rise to its scientific name. It used to be in the genus '' Anaciaeschna'' as it has several differences from the other members of the genus ''Aeshna''. Its specific name is often spelt ''isosceles''. Identification ''A. isoceles'' is one of only two brown hawkers found in Europe, the other is '' A. grandis''. Both have a brown thorax and abdomen but ''A. isoceles'' has green eyes and clear wings and a diagnostic yellow triangular mark on the second abdominal segment. The hindwings have an amber patch at their base. In contrast ''A. grandis'' has yellowish wings and blueish eyes. The green ...

Aeshna Mixta
The migrant hawker (''Aeshna mixta'') is one of the smaller species of hawker dragonflies. It can be found away from water but for breeding it prefers still or slow-flowing water and can tolerate brackish sites. The flight period is from July to the end of October. ''A. mixta'' occurs in North Africa, southern and central Europe to the Baltic region. Identification ''A. mixta'' is a small ''aeshna'' which appears dark in flight. It is similar in appearance to other aeshnas but has a characteristic "golf-tee" shaped mark on the second segment of the abdomen (S2) which is diagnostic. In flight it looks like a small Emperor dragonfly with a blue abdomen which, when seen from the side, curves down. The main identification problem in the field is distinguishing this species from '' A. affinis'' where the two species fly together. The markings on the side of the thorax are different in '' A. affinis'' and ''A. mixta''. In '' A. affinis'' the sides of the thorax are greeny yellow with ...

Aeshna Affinis
''Aeshna affinis'', the southern migrant hawker or blue-eyed hawker, is a dragonfly found in southern Europe and Asia. It is in the family Aeshnidae and is very similar in appearance to '' A. mixta''. Identification ''Aeshna affinis'' is a small ''Aeshna'' and very similar to the related '' A. mixta'' with which it is easily confused. As its name suggests the male has blue eyes and also blue marking on the abdomen. ''A. affinis'' lacks the yellow T-shaped mark which is found on the top of the second abdomen segment in ''A. mixta''. The markings on the side of the thorax are also different in ''A. affinis'' and ''A. mixta''. In ''A. affinis'' the sides of the thorax are greeny yellow with fine black lines along the sutures. In ''A. mixta'' the sides of the thorax are similar in colour but the yellow is separated by dark brown areas so it gives the appearance of having two broad yellow stripes Distribution and habitat ''Aeshna affinis'' is found in southern and central Europe an ...

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.

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 ...
