Dragonflies look delicate, almost imaginary, shimmering wings, metallic colors, impossible aerial maneuvers. But the truth is even stranger than they appear.
These insects once ruled prehistoric skies with wingspans nearly as wide as hawks. Their babies breathe through their anuses. Their eyes contain tens of thousands of lenses. And some migrate across oceans for thousands of miles without stopping.
Dragonflies are not just beautiful insects. They are ancient flying predators engineered with a level of precision that can make modern technology look primitive.
Here are dragonfly facts that prove nature has always been far stranger than fiction.

What Makes Dragonflies So Unusual?
Dragonflies are among the oldest insects on Earth, with ancestors dating back more than 300 million years. Scientists consider them some of nature’s most efficient predators because of their nearly 360-degree vision, independent wing control, and extraordinary hunting accuracy.
Some dragonfly species migrate thousands of miles, while their underwater young breathe through specialized rectal gills, one of the strangest adaptations in the insect world.[1]

Ancient Dragonfly Facts
Prehistoric dragonflies were the size of birds
While modern dragonflies have wingspans of between 2–5 inches (5 cm-12 cm), fossils of dragonflies show that they had wingspans of up to 2 feet.[1]
-
Dragonflies were among the first winged insects to evolve, taking flight over 300 million years ago.[1]

Dragonflies have bejeweled the skies for 300 million years; let's keep them around for 300 million more
-
Scientists recreated “giant dragonflies” in the lab
By placing dragonfly larvae in special chambers that mimic the Earth's oxygen levels from 300 million years ago, scientists have grown super-sized dragonflies that are 15% larger than normal.[1]
-
Their name literally means “toothed one.”
Dragonflies belong to the order Odonata, derived from the Greek word for “tooth,” a reference to their serrated jaws.[1]
-
3. Dragonflies are older than dinosaurs
Dragonflies were already flying through Earth’s skies roughly 100 million years before the first dinosaurs appeared.[3]
-
Dragonflies Are Terrifying Hunters
Dragonfly larvae eat just about anything
Before they ever fly, dragonflies begin life underwater as predatory larvae that hunt tadpoles, fish, mosquitoes, and even each other.[1]
-
Adult dragonflies can eat while they are flying
Dragonflies don’t need to land to feed. They catch prey midair and consume it during flight.[1]
-
Their hunting success rate is almost unbelievable
Dragonflies successfully capture their prey about 95% of the time, making them some of the most efficient hunters on Earth.[4]
-
Luckily,most dragonflies can’t hurt humans
Most dragonflies are harmless to humans and rarely bite, though larger species can occasionally nip if handled.[1]
-
A single dragonfly can eat 30 to hundreds of mosquitoes per day
They are natural mosquito control.[4]

Their Bodies Sound Almost Alien
Dragonfly babies breathe through their anuses.
Dragonfly nymphs pull oxygen-rich water into their rectums, where internal gills absorb oxygen. Additionally, when the dragonfly expels water from its anus, it is propelled forward, which helps the nymph move around.[1]
-
A dragonfly can open its mouth as wide as its entire head.
Their oversized jaws help them grab prey with terrifying efficiency.[1]
-
Dragonflies have nearly 360-degree vision
Their enormous compound eyes allow them to see almost everything around them at once.[2]
-
They can see ultraviolet light
Dragonflies likely experience a version of reality invisible to humans.[2]

Masters Of The Sky
Dragonflies can fly in almost any direction
They can hover like a helicopter, fly straight up and down, and even mate in midair.[1]

Their wings move independently
Unlike many insects, dragonflies control each wing separately, giving them extraordinary agility.[1]

The veins in a dragonfly's wings not only provide structural support but also prevent cracks and tears from spreading throughout the wings
-
Dragonflies will rapidly flap their wings to warm up their bodies
Some dragonflies even use their wings as reflectors, tilting them to direct solar radiation to their bodies.[1]
-
Their flight has inspired flying robots
Scientists study dragonfly aerodynamics to improve drones and robotic flight systems.[1]
-
Dragonflies are surprisingly fast
Some species can reach speeds between 17–38 mph (27–61 km/h).[1]

The Weirdest Dragonfly Facts
One species migrates across entire oceans
The globe skimmer dragonfly can fly across oceans nonstop. The 1.5 inch (3.8 cm) insect logs 11,000 miles (17,700 km), giving them the title of the world's longest insect fliers, able to fly for longer periods of time than any other insect on Earth, including the monarch butterfly.[5]

Would you let one land on your head?
-
In many cultures, it is considered good luck if a dragonfly lands on your head.[1]
-
Depending on the altitude and latitude, some dragonfly species can remain in a larval state for up to six years.[1]
-
Some dragonflies survive in water saltier than the ocean
While most insects cannot live in the ocean, some dragonfly species, such as the seaside dragonlet, produce offspring in water several times saltier than the ocean.[1]
-
The smallest dragonflies are barely larger than a fingernail.
There are several dragonflies in the genus Agriocnemis that take the title of the smallest dragonfly. They have a wingspan of just 17–18 mm or 7/10 of an inch.[4]
-
Dragonflies beat their wings about 30 times per second
By comparison, bees beat their wings about 300 times per second.[1]
-
The largest living dragonfly comes from Australia
The largest currently living dragonfly is Petalura ingentissima from Australia, with a wingspan up to 16 cm (6.2 inches).[1]
-
In some parts of the world, people eat dragonflies
In Indonesia, dragonflies are considered to be a delicious snack.[1]
-
Dragonflies are not related to flies.[1]
-
Because a male dragonfly stores its sperm in a separate place than its copulatory organ, it must transfer its sperm to its penis each time it mates.[1]
-
Even though dragonflies have six legs, like all insects do, they cannot walk.[4]

Dragonflies Feel Like Creatures From Another Planet
Dragonflies existed before flowering plants. Before birds. Before mammals. They survived mass extinctions, shifting continents, and catastrophic climate changes while retaining one of nature’s most efficient body designs.
They are ancient aerial predators wrapped in iridescent glass wings; creatures so strange that, if they appeared for the first time today, many people would probably assume they were science fiction.
