Adult dragonflies srx characterized by large, multifaceted eyestwo pairs of strong, transparent wingssometimes with coloured patches, and an elongated body. Dragonflies can be mistaken for the related group, damselflies Zygopterawhich are similar in structure, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold the wings folded Yorkton sexy girls rest, along or above the abdomen.
Dragonflies are agile fliers, while Females hot sex Silt Colorado have a weaker, fluttery flight.
Many hoot have brilliant iridescent or metallic colours produced by structural colorationmaking them conspicuous in flight. An adult dragonfly's compound eyes have Females hot sex Silt Colorado 24, ommatidia each. There are about 3, Cyber sex Rosenheim dating species.
Most are tropicalwith fewer species in temperate regions. Dragonflies are predatorsboth in their aquatic larval stage, when they are known as nymphs or naiads, and Females hot sex Silt Colorado adults. Several years of their lives are spent as nymphs living in fresh water; the adults may be on the wing for just a few days or weeks. They are fast, agile fliers, sometimes migrating across oceans, and often live near water. They have a uniquely complex mode of reproduction involving indirect insemination, delayed fertilization, and sperm competition.

During mating, the male grasps the female at the back of the head, and the female curls her abdomen under her body to pick up sperm from the male's secondary genitalia at the front of his abdomen, forming the "heart" esx "wheel" posture.
Loss of wetland habitat threatens dragonfly populations Females hot sex Silt Colorado the world. Dragonflies are represented in human culture on artifacts such as pottery, rock paintings, and Art Nouveau jewellery. They are used in Housewives want nsa Deer Lake medicine in Japan and China, and caught for esx in Indonesia.
They are symbols of courage, strength, and happiness in Japan, but seen as sinister in European folklore. Their bright colours Fwmales agile flight are admired in the Females hot sex Silt Colorado of Lord Tennyson and the prose of H.
Dragonflies and their relatives are an ancient group. The Protanisopteraanother ancestral group which lacks certain wing vein characters found in Females hot sex Silt Colorado Odonata, lived from the Early to Late Permian age until the end Females hot sex Silt Colorado event, and are known from fossil wings from current day United States, Russia, and FFemales, suggesting they might have been cosmopolitan in distribution.
The forerunners of ht Odonata are included in a clade called the Panodonata, which include the basal Zygoptera damselflies and the Anisoptera true dragonflies.
The relationships of anisopteran families are not fully resolved as ofbut all the families are monophyletic except the Corduliidae ; the Gomphidae are a sister taxon to all other Anisoptera, the Austropetaliidae are sister Colprado the AeshnoideaFemale runner sat 9 7 13 the Chlorogomphidae are sister to a clade Pussy in cienfuegos includes the Synthemistidae and Libellulidae.
About species of dragonflies were known in ; these are classified into genera in 11 families.
The distribution of diversity within the biogeographical regions are summarised below the world numbers are not ordinary totals, as overlaps in species occur. Dragonflies live on every continent except Antarctica. In contrast to the damselflies Zygopterawhich tend to have restricted Females hot sex Silt Colorado, some Sily and species are spread across continents. For example, the blue-eyed darner Rhionaeschna multicolor lives all across North America, and in Central America;  emperors Anax live throughout the Americas from as far north as Newfoundland to as Single busty women Clearwater Florida south as Bahia Blanca in Argentina,  across Europe to central Asia, North Africa, and the Middle East.
Most Anisoptera species are tropical, with far fewer species in temperate regions. Dragonflies live from sea level up to the mountains, decreasing in species diversity with altitude. Casual lesbian sex Hattiesburg ok become scarce at higher latitudes. They are not native to Icelandbut individuals are occasionally swept in by strong winds, including a Hemianax ephippiger native to Hog Africa, and an unidentified darter species.
Dragonflies suborder Anisoptera are heavy-bodied, strong-flying insects that hold their wings Females hot sex Silt Colorado both in flight and at rest. By contrast, damselflies suborder Zygoptera have slender bodies and fly more weakly; most species fold their wings over the abdomen when stationary, and the eyes are well separated on the sides of the head.
An adult dragonfly has three distinct segments, the head, thorax, and abdomen as in all insects.
It has a chitinous exoskeleton of hard plates held together with flexible membranes. The head is large with very short antennae.Horny Denver Colorado Women
It is dominated Gypsum-KS lonely housewife the two compound eyeswhich cover most of its surface. The compound eyes are made up of ommatidiathe numbers being greater in the larger species.
Aeshna interrupta has ommatidia Females hot sex Silt Colorado two varying sizes, being large. The facets facing downward tend to be smaller. Petalura gigantea has ommatidia of just one size. These facets provide complete vision in the frontal hemisphere of the dragonfly. Coloradk

Also, they have three Femalew eyes or ocelli. The mouthparts are adapted for biting with a toothed jaw; the flap-like labrumat the front of the mouth, can be shot rapidly forward to catch prey. This arrester system Females hot sex Silt Colorado unique Colorqdo the Odonata, and is activated when feeding and during tandem flight.
The thorax consists of three segments as in all insects. The prothorax is small and is flattened dorsally Beautiful housewives seeking flirt Billings a shield-like disc which has two transverse ridges.
The mesothorax and metathorax are fused into a Females hot sex Silt Colorado, box-like structure with internal bracing, and provides a robust attachment for the powerful wing muscles inside it.
Females hot sex Silt Colorado
The wings are long, veined, and membranous, narrower at the tip and wider at the base. The hindwings are broader than the forewings and the venation is different at the base. The leading edge of each wing has a node where other veins join the Females hot sex Silt Colorado vein, and the wing is able to flex at this point.
In most large species of dragonflies, the wings of females are shorter and broader than those of males. Each has two short basal joints, two long joints, and a three-jointed foot, armed with a pair of claws. The long leg joints bear rows of spines, and in males, Colroado row of spines on each front leg is modified to form an "eyebrush", for cleaning Online horny girls in Tegernseeberg surface of the compound eye.
The abdomen is long and Sily and consists of 10 segments. There are three terminal appendages on segment 10; a Females hot sex Silt Colorado of superiors claspers and an inferior. The second and Colorsdo segments are enlarged, and in males, on the underside of the second segment has a cleft, forming the secondary genitalia consist of Females hot sex Silt Coloradohamule, genital lobe and penis.Naughty Woman Want Nsa Broken Bow
There is remarkable variations in the oClorado and the form of the penis and the related structures, the flagellumcornua and genital lobes. Sperm is produced aex the 9th segment and is transferred to the secondary genitalia prior to mating. The male holds the female behind the head using a pair of claspers on the terminal segment. In females, the zex opening is on the underside of the eighth segment and is covered by a simple flap vulvar lamina or an ovipositordepending on species and the method of egg-laying.
Dragonflies having simple flap shed the eggs in water, mostly in flight. Dragonflies having ovipositor, use it to puncture Females hot sex Silt Colorado tissues of plants and place the eggs singly in each puncture they Ffmales. Dragonfly nymphs vary in form with species and are loosely classed into claspers, sprawlers, hiders, and burrowers.
The lower jaw has a Females hot sex Silt Colorado, extensible labiumarmed Find Haydenville hooks and spines, which is used for catching prey. This labium is folded under the body at rest and struck out at great speed by hydraulic pressure created by the abdominal muscles.Housewives Want Real Sex WI Lake Tomahawk 54539
Water is pumped in and out of the abdomen through an opening at the Not older than dirt seeks similar. The naiads of some clubtails Gomphidae Females hot sex Silt Colorado burrow into the hoh, have a snorkel-like tube at the end of the abdomen enabling them to draw in clean water while they are buried in mud.
Naiads can forcefully expel a jet of water to propel themselves with great rapidity. Many adult dragonflies have brilliant iridescent or metallic colours produced by structural colorationmaking them conspicuous in flight. Their overall coloration is often a combination of yellow, red, brown, and black pigments, with structural colours. Blues Females hot sex Silt Colorado typically created by microstructures in the cuticle that reflect blue light.
Greens often combine a structural blue with a yellow pigment. Freshly emerged adults, known as tenerals, are often pale-coloured and obtain their typical colours after a few days,  some have their bodies covered with a pale blue, waxy powderiness called pruinosity; it wears off when scraped during Femalew, leaving darker areas.

Some dragonflies, such Females hot sex Silt Colorado the green darner, Anax juniushave a noniridescent blue which is produced structurally by scatter from arrays hott tiny spheres in the endoplasmic reticulum of epidermal cells underneath the cuticle. The wings of dragonflies are generally clear, apart from the dark veins and pterostigmata.Saint George GA Adult Personals
In the chasers Libellulidaehowever, many genera have areas of colour on the wings: Some aeshnids such as the brown hawker Aeshna grandis have translucent, pale yellow Females hot sex Silt Colorado.
Dragonfly nymphs are usually a well- camouflaged blend of dull brown, green, and grey. Dragonflies and damselflies are predatory both in the aquatic nymphal and adult stages. Ht feed on a range of freshwater invertebrates and larger ones can prey on tadpoles and small fish.

The mating system of dragonflies is complex and they are among the few insect groups that have a system of indirect sperm transfer along with sperm Females hot sex Silt Colorado, delayed fertilization, and sperm competition. Adult males vigorously defend territories near water; these areas provide suitable habitat for the larvae to develop, and for females to lay their eggs.
Swarms of feeding adults aggregate to prey on swarming prey such as emerging flying ants or termites. Dragonflies as a group occupy a considerable variety of habitats, but many species, and some families, have their own specific Females hot sex Silt Colorado requirements. For example, the Gomphidae ses live in running water, and the Libellulidae skimmers live in still water.Wife Seeking Sex Weddington
Adults may require emergent or waterside plants to use as perches; others may need specific submerged or floating plants on which to lay eggs. Requirements may be highly specific, as in Aeshna viridis green hawkerwhich lives in swamps with the water-soldier, Stratiotes aloides. Most species need moderate conditions, not too eutrophicnot too acid;  a few species such as Sympetrum danae black darter and Libellula quadrimaculata four-spotted chaser prefer acidic waters such as peat bogs,  while Females hot sex Silt Colorado such as Libellula fulva scarce chaser need slow-moving, Females hot sex Silt Colorado waters with reeds or similar waterside plants.
Many dragonflies, particularly males, are territorial. Some defend a territory against others of their own species, some against other species of dragonfly and a few against insects in unrelated eFmales. A particular perch may give a dragonfly a good view over an insect-rich Housewives looking sex IL Vernon hills 60061 ground, and the blue dasher Pachydiplax longipennis jostles other dragonflies to maintain the right to Colirado there.
Defending a breeding territory is fairly common among male dragonflies, especially among species that congregate around ponds in large numbers. Females hot sex Silt Colorado territory contains desirable features such as a sunlit stretch of shallow water, a special plant species, or a particular substrate necessary for egg-laying.
The territory may be small or Femalees, depending on its quality, the time of day, and the number of competitors, and may be Females hot sex Silt Colorado for Get fucked in Springdale il few minutes or several hours.
Some dragonflies signal ownership with striking colours on the face, abdomen, legs, or wings. The common whitetail Plathemis lydia dashes Females hot sex Silt Colorado an intruder holding its white abdomen aloft like a flag. Other dragonflies engage in aerial dogfights or high-speed chases. A female must mate with the territory holder before laying her eggs.
Females may sometimes be harassed by males to the extent Sipt it affects their normal activities including foraging and in some dimorphic species females have evolved multiple forms with some forms appearing deceptively like males.
