Odonata is an order of insects, encompassing dragonflies (Anisoptera) and damselflies (Zygoptera). The word dragonfly is also sometimes used to refer to all Odonata. The term odonate has been coined to provide an English name for the group as a whole, but is not in common usage; most Odonata enthusiasts avoid ambiguity by using the term true dragonfly when referring to just the Anisoptera. This order has traditionally been grouped together with the mayflies and several extinct orders in a group called the "Paleoptera", but this grouping appears to be paraphyletic. What they do share with mayflies is the nature of how the wings are articulated and controlled.
It was long believed that the Anisoptera were a suborder and that there existed a third one, the Anisozygoptera (ancient dragonflies). However, they were combined in the suborder Epiprocta (in which Anisoptera is an infraorder) after it was revealed that the Anisozygoptera are a paraphyletic group composed of mostly extinct offshoots of dragonfly evolution.
These insects characteristically have large rounded heads covered mostly by well-developed, faceted eyes, legs that facilitate catching prey (other insects) in flight, two pairs of long, transparent wings that move independently, and elongated abdomens. In most families there is a structure on the leading edge near the tip of the wing called the pterostigma, which actually is a thickened, blood–filled and often colorful area called a cell. Cell in this case means a closed area of an insect wing bounded by veins. The functions of the pterostigma are not fully known, but it most probably has an aerodynamic effect and also a visual function. More mass at the end of the wing may also reduce the energy needed to move the wings up and down. The right combination of wing stiffness and wing mass could reduce the energy consumption of flying. A pterostigma is also found among other insects, like bees. Although generally fairly similar, dragonflies differ from damselflies in several, easily recognizable traits. Dragonflies are strong fliers with fairly robust bodies and at rest hold their wings either out to the side or out and downward (or even somewhat forward). Damselflies tend to be less robust, even rather weak appearing in flight, and when at rest most species hold their wings folded back over the abdomen. Dragonfly eyes occupy much of the animal's head, touching (or nearly touching) each other across the face. In damselflies, there is typically a gap between the eyes.
Odonates are aquatic or semi-aquatic as juveniles. Thus, adults are most often seen near bodies of water and are frequently described as aquatic insects. However, many species range far from water, seeking open fields and hilltops where they prey on smaller insects, catching these in flight. Dragonflies in particular are the raptors of the insect world and absolute masters of maneuverings in flight.

Hi Melina!
This is a very nice portrait of Anisoptera dragonfly (most probably Libellulidae family).
Every single ommatidium is seen!
On the other hand I would try to use "noise reduction" in this photo.
Anyway, very nice picture.
Regards,
Radomir

Hi Melina

Good macro. Clear details and good POV. Nice camera work. :-)

Una auténtica maravilla Melina. Perfectos detalles en esta fantástica macro. Buena iluminación.
Una nota extensa pero instructiva.
Un saludo, JL.

Olá, Melina. Belas cores e bela saturação.

Gosto muito do ângulo e do contato direto. O fundo, além de não distrair, cria contraste.

Belo trabalho.

Very good close up, fine rich colors and details. If you up the contrast or darken just a touch it will eliminate the slight smokey haze in front of the subject. Ciao, Rob

hi melina,
vous êtes spécialisée dans les insectes et la macro à fort grossissement, le résultat est vraiment bon. Toujours intéressant de voir ces détails.

tfs

Fantástica sua foto.
Caso tenha interesse o exemlar da foto parece ser Pantala flavescens (Fabricius, 1798)
Flavescens quer dizer laranja, aloirado etc.
esta espécie é a única de Odonata cm distribuição cosmopolita
Um abraço
