What is a Dragonfly?
The name dragonfly refers to any of about 3,000 species of flying insect found throughout the world, particularly in tropical and wetland regions.
Dragonflies are powerful flying insects, fearsome predators of the insect world. They eat a variety of other insects and have various methods for hunting these insects; most often, they use their superior flying ability to catch their next meal in midair.
Dragonflies lay their eggs in or near freshwater sources, such as ponds and swamps. The eggs hatch into nymphs, which live in the water, hunting water insects as well as tadpoles and small fish.
The nymphs shed their skin multiple times, eventually emerging from the water and morphing into adult dragonflies and gaining their wings. Dragonflies live in the adult stage from a few weeks to several months, depending on the species.
Adult dragonflies tend to be brightly colored and have clear wings, though sometimes the wings also have colored markings on them. They have large heads containing large eyes that nearly touch on the top of their heads; due to eye structure, many dragonflies have nearly 360-degree vision.

Are Dragonflies Dangerous?
Dragonflies are often associated with legends or superstitions. In some parts of the world, they are seen as good luck charms and symbols of prosperity and happiness; but in other regions, they are thought to be associated with death, the devil, and black magic.
Of course, dragonflies aren’t really dangerous; seeing one is not necessarily a bad omen. That said, if you try to handle a dragonfly, you may come away with a painful bite.
Dragonflies are not poisonous or venomous, and their bite isn’t strong enough to draw blood; but it is strong enough to cause momentary pain. Dragonflies don’t make a habit of biting, but they will sometimes bite if they feel threatened.
For this reason, if you catch a dragonfly in a net or attempt to have one sit on your hand, it’s best to wear gloves when handling it. Again, though, dragonflies are not dangerous as their bite will not cause any lasting effects.
Dragonflies are large flying predators of the insect world. They are often brightly colored, and though they are associated with a range of legends and superstitions, they are not dangerous to humans. You can check also this guide on how to help an injured dragonfly.
