Dragonflies attract much attention of naturalists for their vibrant color.  The showy striking color of their body amazes many onlookers.

Odonates (dragonflies and damselflies)  are insects  which contains three Suborders: 1) Anisoptera (dragonflies), 2) Zygoptera (damselflies), 3) Anisozygoptera.

The two former suborders of dragonflies and damselflies are widespread whereas Anisozygoptera is represented by one single species in Japan and one in the Himalayas. 

There are more than 5000  odonate species worldwide. In Malaysia more than 300 species have been found. Dragonflies  are helping  us in  keeping down the numbers of mosquitoes and we tend to forget that mosquitoes form a large part of the diet of many predators including dragonflies and birds.

Photography on dragonflies is now getting popular among the nature lovers. Morning is the best time for a beginner in photography dragonflies. Most dragonflies  require that their flight muscles reach a certain minimum temperature before they are able to fly efficiently. Often insects are sluggish in the morning as they wait for the temperatures to rise enough to get their flight muscles warm. In a cool morning the dragonflies are much more approachable. And the dew condensed on the dragonflies wings often makes for a nice photo.

In  cool, dewcy mornings, one  may find dragonflies covered with dew. They usually hide in a more sheltered spot, among weeds or cattails. They won't be going anywhere until morning sun fully warm them up.

Dragonflies  have favorite perches location. One can get as close as physically possible to the perching site and set up the camera. For macro close up work, a small F-stop is usually required (F16 or so). The dragonfly will leave during the setup, but will normally return within minutes  landing on the same stem tip in the same physical position.

Some dragonflies hunt into the late afternoon aided by their excellent eye-sight. They perch on twigs, grass blades, or leaves at the water’s edge, waiting to grab small insects that come within range.

A dragonfly usually perches with its body in a horizontal position. They  take  an upright posture as if  doing a handstand. It had assumed this “obelisk posture” to cool itself by minimising the rays of the sun ray to the body.

Dragonflies are usually found near ponds, lakes, rivers, or even puddles of water that are quite permanent. When they are not flying, you can find them perching on leaves or twigs at the water’s edge.

Dragonfly are magnificent flying machines. It can fly at speeds of nearly 100kph. It can hover like a helicopter, fly vertically, stop or turn sharpy in the midst of rapid flight, even fly backwards. It has the best eyesight among insects.

蜻 蜓

蜻蜓的交配也是在飛行中進行的。雄蜻蜓用腹部末端的把握器抓緊雌蜻蜓的頸部;雌蜻蜓腹部由下向前彎,把生殖孔接到雄蜻蜓腹部第二節下面的貯存精子器官,然後雄蜻蜓才進行授精。產卵時,大多是邊飛邊用尾部碰水面,把卵排出。我們常見的所謂「蜻蜓點水」,就是雌蜻蜓產卵的表演動作。蜻蜓還有「領域佔據」的習性,雄性的蜻蜓為了覓食及搶得與雌蜻蜓交尾配對的機會,常會發生爭奪地盤而互相追逐的場面。


蜻蜓交尾

蜻蜓交尾的方式非常獨特,雌雄會形成"輛狀",雄的在上用尾部緊緊拑著雌性的頭部或胸部,在下的雌性會彎曲腹部貼著雄性的第三節腹部,這時精子和卵子便會結合.交尾的時間由數分鐘至數小時不等.一般雄蜻蜓會伴著雌蜻蜓直至產卵才分開......


蜻蜓的頭與胸部連結的部分較窄,使頭部能夠上下左右轉動,且有一對大複眼,視覺非常敏銳,能夠在空中追擊或攔截一些動作慢的飛翔昆蟲,所以是空中的惡棍。

捕捉的昆蟲包括蜜蜂、蛾類,甚至較小的蜻蜓。

Feats and  Facts


Fossils of prehistoric dragonflies have been found with wingspans of 30 inches and body lengths up to 18 inches.

Adults of Odonata can fly backwards or forwards and even hover like a helicopter. They can do these incredible aerial tricks because their two pairs of wings move independently of each other, in contrast to most other insects.

The fastest recorded insect flight belongs to the Australian dragonfly, Austrophlbia costalis, which can reach 36 miles per hour over short distances.

Some dragonflies can have between 10,000 and 50,000 individual eyes (commatidia) in each compound eye.

The naiad shoots out its labium very fast to catch a prey, and the forward movement requires less than three one-hundredths of a second.

The common green darner found in the United States, Anax junuios, migrates north into Canada each summer. In the fall, the offspring of these dragonflies will make their way back to the south.

The largest damselfly, Megaloprepus coerulatus, has a wing spread of more than seven inches. This damselfly is found in Central and South America.

A dragonfly nymph can use jet propulsion to move forward very quickly. By pulling water into the rectal chamber of its abdomen and then shooting it out.

The word for dragonfly in Japanese is "tombo", but many years ago dragonflies were called "akitsu." Japan was once called Akitsushima, meaning "The Island of the Dragon-fly."

Odonates are insects with two large compound eyes, two pairs of delicate and membranous wings, and a long slender abdomen. Their life history occurs in two different stages: aquatic and aerial stages. The larval stage is spent in aquatic environment, and the adulthood is in terrestrial.

Both the larvae and adults are good hunters. Prey may be stalked or ambushed.

Dragonflies receive less attention due to their less economical significance compared to other insects such as butterflies.

Yet, they are good  indicator for aquatic ecosystem, and the larvae (nymphs) are proven to be good biocontrol of insect pests.


Adult dragonflies and damselflies catch and eat insects while flying. They eat anything small enough for them to handle, including flies, wasps, moths, and beetles. Adults often fly  away from their nymphal home in the water to another area where they feed for several weeks before returning to the pond, lake, or stream to mate and lay eggs.


Mating of dragonflies and damselflies is peculiar in that the mate holds the female behind the head while the female receives the male reproductive cells.

Mating pairs will stay clasped for several minutes to several hours depand on species. They even fly while joined together.


Dragonflies and damselflies undergo incomplete metamorphosis (egg-nymph-adult). The eggs are laid in water or in water plants and hatch into an aquatic nymph (naiad). The naiad stage lasts for a few weeks to almost five years. The nymphs must shed their skin, or molt, in order to grow in size, and they can molt 10 to 15 times before becoming mature. The mature nymph crawls out of the water onto the stem of an aquatic plant, where the adult emerges from the skin of the nymph, dries, and expands its wings, and flys away in search of food.


Dragonflies are different from damselflies

 Dragonflies hold their wings out from the body when at rest.

 Damselflies rest with their wings held together over their backs.


Dragonflies and damselflies wings are transperant with many veins. Most species in Sabah have beautiful color patterns. The coloration of the male dragonfly often differs from that of the female.


Their mouthparts include large mandibles for biting and chewing. They have small hairlike antennae.


There are 5,000 species of dragonflies and damselflies. About 500 to 1500 species are to be described and named in the world.

 


Dragonflies and damselflies have large compound eyes that can see in all directions. When the compound eye is magnified several hundred times, each individual facet (ommatidium) is shown to be hexagonal in shape.

A Guide to the Dragonflies of Borneo: Their Identification and Biology By: Orr A G

The first guide to the dragonflies of Borneo Island. The most comprehensive coverage for any tropical region. 275 species (60%) occurring on the island are described and illustrated in photographs and 25 beautiful plates of 1/2-wing drawings. Chapters on biology, classification and ecology, as well as a complete checklist. 19.5 x 26.5 cm.

Many more yet to be discovered, Borneo has one of the richest and most exciting dragonfly faunas in the world. More than 40% species found nowhere else, making Borneo the most distinctive sub-region of Sundaland. It is home to such spectacular species as Tetracanthagyna plagiata, the heaviest of all dragonflies, many beautiful picture-winged chlorocyphids and euphaeids, and high-altitude endemics such as Matronoides cyaneipennis restricted to Mount Kinabalu and nearby mountains.

 
The first guide to Borneo’s dragonflies, is also the most comprehensively illustrated account of any large tropical dragonfly fauna yet published. Species are figured by natural photographs and half-wing drawings. About 60% of known species are shown, including almost all the distinctive and common species likely to be encountered by a casual visitor. Particular attention is given to the identification of the common but difficult medium-sized red dragonflies of which there are several.

The text augments the illustrations and provides useful information on biology. Introductory chapters discuss structure and general biology, ecology and conservation, faunistics and biogeography and collecting techniques and photography. There is a complete and up to date checklist. Illustrated keys to families of adults give the reader an understanding of the structures used in classifying dragonflies and augment the usefulness of the illustrations of entire insects. Main larval forms are shown. This book will be useful not just in Borneo, but also in neighboring parts of south-east Asia.

Dragonflies are among the most beautiful of insects. Peninsular Malaysia and Singapore are home to more than 230 species (twice the number found in Europe). They include some of the most exquisite forms found anywhere in the World. They occur wherever there is suitable fresh water habitat. Many species frequent the borders of garden ponds in our largest cities, perching on lily pads with glowing red bodies in striking contrast to their green platform. Others haunt swift clear streams in virgin rainforest, while yet others are confined to blackwater swamps. A few occur deep in the forest understorey, far from streams or pools, where they breed in the water accumulated in cavities in tree trunks. This book figures 98.7% of species known from Peninsular Malaysia and Singapore. For most, coloured drawings of the whole insect (omitting one pair of wings) are provided. Where necessary, coloured or monochrome drawings showing diagnostic features are also included. For some species, especially small Zygoptera (damselflies), only detailed structures are figured, as the general resemblance between close species is strong. A wide range of larval types is also figured.
