Tachopteryx thoreyi, (Grey Dragonfly)
This dragonfly Belong to the class Insecta and is a member of one of the oldest family of insects that still exist today the phylum Arthropoda (Dragonflies) family.
Phylum Arthropoda family. (Dragonflies)
The first Arthropoda have segmented bodies and an external skeleton. It is believed that the entire kingdom Animalia evolved from the same ancestor. This ancestor is believed to have been a colonial flagellated protist, found in the Precambrian era, more than 700 million years ago. Also, most of them have compound as well as median eyes. Their body is open on the inside.
The dragonfly of today has bulbous eyes, six legs, a very long slender segmented body and large elongated wings. There are about 3,500 species. Their colors vary greatly, from dull gray to vivid reds and greens and blues. Size can range from less than an inch long to 3 ½ inches long. Dragonflies belong to the order Odonata (“toothed ones”). Odonates are found all over temperate areas of the world, in all different types of habitats. They must have access to clean water, as the eggs are laid in or near water, and the nymphs live in water or wet soil. The grey petaltail dragonfly is the only species in the genus Tachopteryx. It belongs to the family Petaluridae. The order Odonata includes suborders zygoptera (damselflies), anisozygoptera and anisoptera. Many people call all Odonata dragonflies, however, only anisoptera are actually dragonflies. Anisoptera wings are perpendicular to the body, while Zygoptera wings are held parallel. Anisozygoptera only have a few living species. The grey petaltail, or tachopteryx thoreyi is considered to be phylogenetically primitive, which means structurally, it has changed very little from its prehistoric ancestors. The Petaluridae family was one of the larger families during the Mesozoic era. Today there are only 9 Petaluridae species in the world. The tachopteryx thoreyi is one of two species of the family Petaluridae, or Petaltails, that live in North America. They are the largest mostly grey dragonfly in the Eastern United States It is one of few species that have a habit of perching on tree trunks. Dragonflies do not bite or sting humans. However, females of some species have sharp blades in their ovipositors, which aide in depositing eggs. If a female with blades lands on a human mistaking a leg for a tree trunk, it may stab the leg with its ovipositor, while trying to lay eggs. Dragonflies are credited with keeping numbers of mosquitoes low. Presence of dragonflies is a good indicator of a healthy ecosystem.

Hi Jorge,
Lovely capture. I like the limited colour palette, blues and greens, which simplifies the image nicely.
Thanks

Hola Jorge, yo nunca había visto una de este color, me fascina ese tono gris azulado, de hecho uno de mis deseos es poder fotografiar de cerca a alguna libélula azul, espero que se cumpla en el mes de abril, me encantan las libelulas de ese color y aun no logro fotografiarla de cerca. Me gusta mucho la composición además de que captaste a la libélula con preciosa nitidez, cristalina, esos ojos y su brillo son un gran atractivo en la foto, (sin duda una de mis favoritas) es una toma nocturna verdad? porque ese fondo obscuro le añade una atmósfera especial,
