Delifies are among the oldest insects
Introduction
The dragonflies are among the oldest insects of which there is knowledge, it is estimated that they have been flying for more than 300 million years. These insects usually live near the water, since their young are aquatic, they need water to complete their first life cycle of approximately 2 years. While the dragonfly has six legs, they are not the best to walk. When flying, however they are usually excellent. They can fly at large speeds and even catch their prey in the air.

What is fed the dragonfly?
All dragonflies are carnivorous in the larval and adult stages of their lives. They usually feed on other insects such as flies or mosquitoes. Although sometimes they eat other larger ones such as butterflies, moths and even smaller dragonflies.
This insect is not able to chop the human being, but it can try to bite it, although it is not able to cause any damage to the skin. That is why it is considered a rather harmless insect.
Adult dragonflies should be careful with their predators: birds, reptiles, spiders or folds of larger. Although the greatest danger passes by being larvae, since they are susceptible to becoming the food of other animals that live just like them in lakes and swamps.
Its physical characteristics
The dragonflies have two big eyes that occupy most of their head. Like flies, they have six legs and their body is divided into three parts: head, thorax and abdomen. The only difference with flies is that the dragonfly has four large wings while the fly has only two.
The wings of this insect are really striking, they distinguish for being membranous and transparent. Some of them can present a light yellow color on the tips. In addition your body is very colorful, some may present the green thorax and bluish abdomen. Others are red and yellow.
conclusion
The dragonfly is undoubtedly a wonderful insect that is worth appreciating. Breathe through spiracles (small holes located in your abdomen) and can move your wings together or separately. They are also excellent aviators, they can fly up, down, float like a helicopter and even mate in the air.
If they could not fly, they would die hungry, since they only eat insects that get caught while flying. Did you know that the dragonfly flight is so special that even engineers dream of making robots that fly like them?
