Dragonflies and damselflies (together known as Odonata) are among the most remarkably distinctive insects in their appearance and biology, and they have become some of the most popular creatures sought by avocational naturalists.

 

Dragonflies have been perfecting their flight tactics for a long time. The earliest known fossils of dragonfly-like insects are from the Carboniferous period; these 325 million year old eugeropterids, as they are called, were roughly similar in size to modern dragonflies, but they had 3 pairs of wings. The 3rd pair was much reduced in size and it is thought to have acted as an airfoil to provide additional stability in flight. The meganeurid dragonflies which graced the skies during the Permian 250-300 million years ago more closely resembled our modern dragonflies but on a much larger scale; specimens found in Oklahoma and Kansas show wingspans of 27-28 inches. Fossils of what appear to be modern families of Odonata have been found beginning in the Jurassic period, about 145-200 million years ago.

 

Sometimes the wing patterns of a Dragonfly are so distinctive that no other clues are necessary for identification. Such is the case with the Four-spotted Pennant (Brachymesia gravida). It is the only dragonfly with a rounded spot and a white stigma (the little opaque mark on the leading edge of the wing near the tip) on each wing. This can be a very common dragonfly at times, but they are difficult to approach. Other characteristics include a very slender abdomen that is quite swollen at the base, and brown color in the female and black in the male.

 

I believe this is a female Four-Spotted Pennant which I found on the shore of Lake Kissimmee at Joe Overstreet Landing in Osceola County, Florida.

 

I have been advised by the expert himself Mr Vince Capp that this is a juvenile male and not a female. Thanks Vince for keeping me on the right track.

There wern't many butterflies at the gardens for some reason but there were plenty of dragonflies.

 

This little guy was drinking in the morning sunlight when I first arrived.

A wasp? No, this is a tiny dragonfly that appeared to be a wasp at first sight. Eastern Amberwing Dragonfly - Morgan County, Alabama - 2017

Caught this little Amberwing out in the front yard this afternoon. I've had two young grandchildren staying here the past few days so haven't been able to check out your recent posts but will get back to you soon.

A picture sometimes conerys a feeling.,, and this for us was one of those., it has that 'summer' feeling that we will long for once the long months of winter arrive and everything is looking so grey and dead.

Dragonflies are one of the only creatures on this planet that undergo a complete transmutation from a water nymph to a winged dragonfly. The spirit of dragonfly is special, and they are messengers to those who are listening.

I sat patiently for 45 minutes watching this Dragonfly, waiting for it to land and then when it did I only managed 2 shots before it took to the air again

For me is amazing to photograph tiny insects like the dragonflies. Incredible acrobats and they don seem to mind being photograph at all. The down part of photographing these guys is that you have to get into the skirts of lakes or rivers to get close to them, and by doing that get dirty, but their photos are amazing!

Photography is my passion, and nature photography is my favorite.

 

I have been in Explore for more that a hundred times, and it is an awesome experience to have your photos showcased in such a special way.

 

I'm in many groups, and I only add my photos to them if they are not private.

 

I thank your for coming today, for leaving a comment, and make a favorite of yours this photo, (if that is the case) thanks again!

 

The best part of this forum is the contacts and friends that I have made over the years, that have the same passion for this art that is called photography!

 

Martha,

Emperor Dragonfly (Anax imperator).

Besides all the great birds that were attracted to the feeders and flowers at the Harrison's house, dragonflies ocassionally landed on the flowers. The 500 made for a decent "macro" lens as well.

 

Cerro Azul, Panama. February 2017

Heat and humidity here. Lots of things are flourishing.

First time I saw a dragonfly with prey eating on a blade of grass.

 

Many thanks for your continued visit and support:)

I was walking around looking for wildflowers to photograph when this beauty came flying by, the more photos I took of her the closer she let me get! She is quite colorful!

  

With a big smile on his face!

Dragonfly’s eyes have about 30,000 lenses and have a full 360-degree field of vision, but they don’t see details very well. A human eye only has one lens and sees better than a dragonfly, but only to the front and side.

Typically dragonflies are very flitty creatures but this one was quite friendly and let me take a nice macro shot of him.

It's so difficult to take a picture of a dragonfly under the sun of Miami! Enjoy and let me know if you like it!

Dragonflies - Libelle

 

The dragonflies (Odonata) form an order within the class of insects (Insecta). Of the 5680 known species (as of 2008) [1] in Central Europe occur about 85. The wingspan of the animals is in general between 20 and 110 mm, the type Megaloprepus coerulatus (Zygoptera, Pseudostigmatidae, so a "small" dragonfly), however, can even reach a maximum span of 190 mm.

No crop...just as framed in the camera. File size reduced. Most satisfying detail shot yet of one of these dragonflies. Large is nice.

Dragonflies and damselflies are large, conspicuous insects often found close to fresh water. The Order Odonata is divided into two suborders, the Anisoptera containing the dragonflies, and the Zygoptera containing the damselflies. Odonata closely resemble the oldest flying insects known from fossils. These fossil 'dragonflies' were very large, with one species reaching 71 cm in wingspan.

Adult dragonflies are generally stout bodied and when at rest spread their wings out to the sides. Damselflies are generally more delicate and hold their wings along their body when at rest.

The larval stages of the two suborders can be distinguished by the placement of the gills. Dragonfly larvae suck water into their abdomen and move it over their internal gills. Damselfly larvae have gills at the end of the body as three appendages.

Like many insects, the larval and adult stages of dragonflies and damselflies differ in their shape and behaviour and use different habitats.

Eggs are laid into, or close to, water. The larvae adopt an aquatic lifestyle, with only a few exceptions. They feed on aquatic animals such as other insects, tadpoles and occasionally fish. Some larval dragonflies and damselflies are commonly known as 'mudeyes'. They are important in the diets of many aquatic predators such as fish. After progressing through up to twelve larval stages the larvae crawl out of the water. Their skin splits and the adults emerge. The adults are predators that often capture prey while flying.

The adult stage has a pre-reproductive period that may last up to three weeks. At this stage the colour of the wings and body may change and the adults may disperse from their emergence point.

The reproductive phase may involve the establishment of territories by males, which are protected against other males of the same species. Copulation involves the male grasping the female behind the head with appendages on his abdomen while she bends her abdomen underneath his thorax to recover a packet of sperm that he has placed there. Adults may be seen flying in this tandem position
