How big is the dragonfly? I can't believe it has so many eyes!

We all know that dragonflies, which are insects flying in ponds or rivers, are called giant vein dragonflies, which are said to be the largest species of insects that have ever appeared on earth. So, how big is the dragonfly?

How big is the dragonfly?

1. The giant vein dragonfly, also known as the big-tailed dragonfly and the giant-tailed dragonfly, is an insect of the Carboniferous period 300 million years ago. it is similar to modern dragonflies in appearance, but it became extinct as early as 250 million years ago in the Permian. Its fossils were discovered in France in 1880.

2. The giant-veined dragonfly is the largest known insect species on earth, with wings spreading up to 2.5 feet (75 cm) wide, while ordinary dragonflies have a wingspan of 16 cm and the smallest species have a wingspan of 2 cm. By comparison, the giant vein dragonfly is huge, and scientists believe that how it grew into such a huge size in the Carboniferous period was due to the high oxygen content in the air at that time.

3. Because of its large size, giant dragonflies eat insects and small amphibians and have few natural enemies, while ordinary dragonfly larvae prey on wigglers or other small animals in the water, and adults prey on mosquitoes, flies, butterflies, moths, bees and other pests. But the air overlords eventually became extinct, probably due to a drop in oxygen levels, because they could not adapt to the environment at the time, leading to extinction.

How many eyes does a dragonfly have?

1. Dragonfly is the insect with the largest number of eyes in the world. Its eyes are large and bulging, occupying most of its head. It has three single eyes, and its compound eye consists of more than 28000 small eyes. Although humans can see a colorful world of red, blue and green, dragonflies have up to 33 different photosensitive proteins and may see more colors than humans.

2. Dragonflies are the winged insects with the best vision in the animal kingdom. they have excellent eyesight, and they can look up, down, forward and backward without having to turn their head, and their compound eyes can also measure the speed of their compound eyes. each "small eye" reacts in turn, and the speed of the target object can be determined after processing.

How many pairs of wings and legs does a dragonfly have?

1. Dragonflies have two pairs of wings, the front and rear wings are equally long and narrow, membranous, and the veins of the reticular wings are extremely clear, with a wingspan of 5 centimeters generally. As an excellent aviator in the insect kingdom, dragonflies swing their wings 30 to 50 times per second at high speed, up to 10 meters per second, and can not only turn suddenly, but also go straight into the sky, and sometimes fly backwards.

2. Dragonflies have six legs, grow on the chest, are close to the head, are thin and weak, and have hooks on them, which can catch pests when flying in the air, but the hatched larvae have no feet and have simple feet after the first peeling.

The giant-veined dragonfly is the largest known insect species on earth. its wings are 2.5 feet (75 centimeters) wide, much larger than ordinary dragonflies and feed mainly on other insects and tiny amphibians, but eventually become extinct. Dragonflies are not only the insects with the most eyes in the world, but also the winged insects with the best eyesight in the animal kingdom. they can not only see more colors than humans, but also can see all directions at the same time without having to turn their head.
