History shows that petaluridae originated in what is known as New Zealand today. The praying mantis is from the order Mantodea. [79], Dragonflies are affected by three major groups of parasites: water mites, gregarine protozoa, and trematode flatworms (flukes). Also known as darner, devils darning needle, and devils arrow, these winged insects were some of the first flyers to evolve over some 3000 million years ago. It has a chitinous exoskeleton of hard plates held together with flexible membranes. Dragonflies having ovipositors use them to puncture soft tissues of plants and place the eggs singly in each puncture they make. The many types of dragonflies are a reason that some people confuse them with other insects. Gliding, with the wings held out, is used in three situations: free gliding, for a few seconds in between bursts of powered flight; gliding in the updraft at the crest of a hill, effectively hovering by falling at the same speed as the updraft; and in certain dragonflies such as darters, when "in cop" with a male, the female sometimes simply glides while the male pulls the pair along by beating his wings. You can also subscribe without commenting. Some water scorpions hide among dead leaves. Only dragonfly nymphs have internal gills, called a branchial chamber, located around the fourth and fifth abdominal segments. 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" or "wheel" posture. 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 above the abdomen. In Indonesia, adult dragonflies are caught on poles made sticky with birdlime, then fried in oil as a delicacy. Their wings are also much shorter and haven't developed the characteristic veined pattern that adults have.

[27][29][30][31], Dragonfly nymphs vary in form with species, and are loosely classed into claspers, sprawlers, hiders, and burrowers. Favorite kinds of dragonfly food include: Dragonflies are strictly carnivorous insects. They range in color, including the blue-spotted ones. These include falcons such as the American kestrel, the merlin,[76] and the hobby;[77] nighthawks, swifts, flycatchers and swallows also take some adults; some species of wasps, too, prey on dragonflies, using them to provision their nests, laying an egg on each captured insect. Owlflies have long, clubbed antennae. [84] Over 60% of Japan's wetlands were lost in the 20th century, so its dragonflies now depend largely on rice fields, ponds, and creeks. Females may sometimes be harassed by males to the extent that it affects their normal activities including foraging and in some dimorphic species females have evolved multiple forms with some forms appearing deceptively like males. [71] Dragonflies are also some of the insect world's most efficient hunters, catching up to 95% of the prey they pursue. Depending on the type, the abdomen of a skimmer is either thick or super thin.

Tigertails are one of the oldest species of dragonflies and are most commonly found in Australia and New Guinea. Light is sent down flexible light-pipes named optrodes[c] from the backpack into the nerve cord to give steering commands to the insect. Unlike other common dragonflies, theirbodies do not look metallic, and they have a toneddown hue to avoid instant recognition.

The long leg joints bear rows of spines, and in males, one row of spines on each front leg is modified to form an "eyebrush", for cleaning the surface of the compound eye. Most Anisoptera species are tropical, with far fewer species in temperate regions. These dragonfly species belong to the Odonata order which means toothed one in Greek. [37], The wings of dragonflies are generally clear, apart from the dark veins and pterostigmata. Nymphs of Cordulegaster bidentata sometimes hunt small arthropods on the ground at night, while some species in the Anax genus have even been observed leaping out of the water to attack and kill full-grown tree frogs. Debbie Hadley is a science educator with 25 years of experience who has written on science topics for over a decade. The large, clubbed antennae of the adult antlion easily differentiate it from a damselfly. (making them look like they are carrying saddlebags) and huge reddish eyes positioned in the back of the head. [74] A dragonfly can see in 360 degrees, and nearly 80 percent of the insect's brain is dedicated to its sight. [25], In high-speed territorial battles between male Australian emperors (Hemianax papuensis), the fighting dragonflies adjust their flight paths to appear stationary to their rivals, minimizing the chance of being detected as they approach. Any member of the suborder Zygoptera of the predatory aerial insect family Odonata is referred to as a damselfly. There is a little dramatic flair to the story. However, as these flies begin to develop, they start feeding on larger species such as microcrustacea. However, their superior visual acuity and sensitivity to vibration make it possible for them to expertly navigate their environment. Moreover, these dragonflies also take ages to grow into an adult.

They are predators and can eat other insects, even while they are flying. Most species need moderate conditions, not too eutrophic, not too acidic;[41] a few species such as Sympetrum danae (black darter) and Libellula quadrimaculata (four-spotted chaser) prefer acidic waters such as peat bogs,[42] while others such as Libellula fulva (scarce chaser) need slow-moving, eutrophic waters with reeds or similar waterside plants.

In females, the genital opening is on the underside of the eighth segment, and is covered by a simple flap (vulvar lamina) or an ovipositor, depending on species and the method of egg-laying. [55] They breathe through gills in their rectum, and can rapidly propel themselves by suddenly expelling water through the anus. Some fossil Odonata ancestors have wingspans of more than 28 inches. Luckily for them, they have a killer lip that snatches pre. It is believed that male saddlebags approach their female counterparts and roam around them.

These are some of the most common dragonfly species and are spread worldwide. In the water, various species of ducks and herons eat dragonfly nymphs[76] and they are also preyed on by newts, frogs, fish, and water spiders. Early in the morning, they may choose to perch in a vertical position with the wings outstretched, while in the middle of the day, a horizontal stance may be chosen.

[50] The pair flies in tandem with the male in front, typically perching on a twig or plant stem. This behaviour involves doing a "handstand", perching with the body raised and the abdomen pointing towards the sun, thus minimising the amount of solar radiation received.

The mouthparts are adapted for biting with a toothed jaw; the flap-like labrum, at the front of the mouth, can be shot rapidly forward to catch prey. Nymphs feed on a range of freshwater invertebrates and larger ones can prey on tadpoles and small fish. Species Group. [92] For the Navajo, dragonflies symbolize pure water. These dragonflies are regarded as burrowers and sprawlers as they burrow well deep into the substrate, allowing only their head to be visible. Flies have large compound eyes that occupy most of the head, while bees have narrow compound eyes on the sides of the head. Anchoring itself firmly in a vertical position with its claws, its exoskeleton begins to split at a weak spot behind the head. At the same time, more research into dragonflies needs to be done, consideration should be given to pollution control and the public should be educated about the importance of biodiversity.
