[Note Guidelines] Photographer's Note
The Dragonfly (suborder Anisoptera) is an insect belonging to the Order Odonata. It is characterized by large multifaceted eyes, two pairs of strong transparent wings, and an elongated body. Dragonflies typically eat mosquitoes, midges and other small insects like flies, bees, and butterflies. They are usually found around lakes, ponds, streams, and wetlands for the reason that their larvae (known as nymphs) are aquatic. Dragonflies do not bite or sting humans.[1] In fact, they are valued as a predator that helps control the populations of insects that do, such as mosquitoes.

The life cycle of the dragonfly, from egg to death of adult, varies from six months to as much as six or seven years. Female dragonflies lay eggs in or near water, often in or on floating or emergent plants. Most of their life cycle is spent in the larval (nymph) form, beneath the water surface, using internal gills to breathe, catching other invertebrates or even vertebrates such as tadpoles and fish. In the adult (flying) stage, larger species of dragonfly can live as long as four months. Dragonflies have very good eyesight due to their unique eye structure. Dragonflies have up to 30,000 facets to their eyes, each one is a separate light-sensing organ or ommatidia, arranged to give them nearly a 360 field of vision.

Much larger dragonfly species existed in the distant past than occur on earth today. The largest, found as a fossil, is an extinct Protodonata named Meganeura monyi from the Permian period with a wingspan of 7075 cm (27.529.5 in). This compares to 19 cm (7.5 in) for the largest modern species of odonates, the Hawaiian endemic dragonfly, Anax strenuus. The smallest modern species recorded is the libellulid dragonfly, Nannophya pygmaea from east Asia with a wing span of only 20 mm, or about 3/4 of an inch.

The Common Green Darner dragonfly (Anax junius) is nicknamed "Darning Needle" because of its body shape. It is one of the biggest and fastest-flying dragonflies, able to reach speeds of 85 km/h (53 mph).

Damselflies (Suborder Zygoptera) are often confused with dragonflies, but the two insects are distinct: damselflies at rest hold their wings together above the body, whereas dragonflies at rest hold them out, either horizontally or slightly down and forward. Also, the eyes on a damselfly are separated, while those of the dragonfly are nearly touching. Both are members of Odonata, and their life cycles are similar.

Hi Behrad!
The focus is a bit soft on the wings, but, by and large, it is a nice picture of this skimmer or darter dragonfly.
You have a great camera and I am sure you will be able to use it to great effect soon.
Welcome to TN.

Hi Behrad,
it's a pretty dragonfly and you catched it in a nice pose with a good point of view.
I like it, thanks and bye

I make my dragon-shots with the flash, so I have higher exposure and more sharpness on the wings ;-)

Cool macro shot. Sharpness is spot on

Hej Behrad!
Ladne macro! Widac jak wazka macha skrzydelkami. Wazka dobrze wyeksponowana na rozmytym tle.
Gratuluje i pozdrawiam - Roma
