All About Dragonflies

Is a dragonfly a fly?
No. Flies are insects with two wings. Dragonflies have four wings. However, both flies and dragonflies are insects, meaning that they have six legs and three body parts: a head, a thorax, and an abdomen.

Why are they called dragonflies?

The name comes from their fierce jaws, which they use to catch flies (among other winged insects).

Where do dragonflies come from?

The dragonfly begins its life as an egg. Adult female dragonflies lay their eggs in water. After about two weeks, the eggs hatch and an immature dragonfly, or nymph, emerges. The nymphs are not pretty like the adults. They have tiny wings and a large lower lip, which they use to catch their prey (often mosquito larvae). Dragonfly nymphs live in the water. As they grow, they molt (shed their skin). Nymphs of some species may take as long as three years to mature.

When the dragonfly nymph reaches maturity, it crawls out of the water onto a plant stem. Then its skin begins to split. First the head, then the thorax, then the legs, and then the wings of an adult dragonfly emerge. Soon the newly emerged dragonfly is able to fly. The process takes about two hours. It takes about two days before the adult dragonfly's beautiful colors are fully developed. Adult dragonflies live only a few months.

How long have dragonflies been around?

Dragonflies are ancient insects. They were around before the dinosaurs! Ancient dragonflies may have been considerably larger than those we see today. A fossilized impression of a dragonfly wing, found in a coal mine in England, is the oldest known dragonfly specimen. This dragonfly lived 300 million years ago and had a wingspan of eight inches. The largest known dragonfly had a wingspan of 24 inches (two feet). Today, the largest dragonfly is found in South America and has a wingspan of slightly over seven inches. Other than being smaller, modern-day dragonflies do not look very different from their ancestors.

Are dragonflies like other insects?

Dragonflies and damselflies belong to an order of insects all their own, called Odonata. Although the two are similar, damselflies are smaller than dragonflies. In addition, damselflies can fold their wings over their backs when they are at rest. Dragonflies can't fold their wings, so they rest with their wings held straight out.

Are dragonflies beneficial to humans?

You bet they are! In fact, dragonflies are sometimes called "mosquito hawk" because they catch and eat so many mosquitoes. Always on the hunt, dragonflies consume gnats, flies, and mosquitoes--all of which humans consider pests.

Why are dragonflies such good hunters?

Dragonflies' ability to maneuver makes them able to out-fly their prey. But dragonflies also have the advantage of excellent eyesight. If you've ever watched dragonflies, no doubt you have noticed their huge eyes. Each of the two large eyes is made up of thousands of six-sided units. Together, these smaller eyes enable a dragonfly to detect even the slightest movement. To test this, try sneaking up and catching a dragonfly. You usually come up empty-handed.

Hi Pankaj,
You've capture fine rich colors and detail on this dragonfly.
Great POV to show the face. Amazing eyes.
Presented well in the frame.
A bit more DOF to focus wings would be a plus.

Hello Pankaj,
an excellent shot with a brilliant note.
Very sharp and crisp with an excellent DOF.
Perfect BG.
Well done,
Joe

Between you and Sumon....there are no better in this arena, in my eyes. Some may see it another way of course. That is only human....but your work as well as Lawhill, is above good...setting a benchmark.

Hello Pankaj,

A very interesting diagonal composition! I don't see this way of composing an image by having the empty space placed on one half of the diagonally split picture and the subject on the other side. The blurred background emphasizes the dragonfly and makes the sharp details look even sharper. I also liked the natural colors and enjoyed the notes. Very well done! Thanks!

With Friendly Regards,
Eddie

Hello Pankaj,
Superb capture of a species of Club-tail dragonfly with excellent sharpness and detail, neutral BG and fine diagonal composition. Good use of flash too.
Well done and TFS!

This time you nailed a dragonfly instead of your usual butterfly atop lantana flowers, Pankaj.
This species of dragonflies is new to me and I have really enjoyed looking at its very individual features and colours.
The focus on the eyes and thorax is sharp as razor. Would like to know more about the species, though.
Thanks for sharing the picture, which, if I recall correctly, is one of the rare contributions from a butterfly expert.
Regards and take care.

bonjour pankaj
oh quel beau specimen,je note juste un manque de profondeur de champ qui se traduit par le bout de l'abdomen un peu flou.

Hi Pankaj.
What a superb shot of this amazing dragonfly. Pictures scene, its characters are great. Bright colours are excellent, composition is outstanding as well as the POV. For such subject the larger DOF is better. I think the ISO speed could be faster a bit. My compliments and TFS. Perfect job.

Hi Pankaj,
Wonderful shot of this beautiful one. Even I have a shot of this and thanks to you I atleast know its ID now. Very sharp image and neat focus on its eyes. The lantanas act as a nice perch again. Excellent POV to portray it and very nicely composed. Kudos.
TFS.

Hello Pankaj,
An excellent note to go with an excellent picture. Beautiful composition with the focus on the wonderful blue eyes of the dragonfly. Not easy to take pictures with such a pose. The blurred background is a beautiful contrast to the brighter colours of flower and insect. Well seen
Anne

Bel et attrayant mélange de couleurs.
Bonne journée.
