With one species reaching speeds of 58 kilometers (36 miles) per hour, dragonflies are the world's fastest flying insect.

Dragonfly migration season is believed to run from August to November

Researchers know much less about dragonfly migrations than they do about bird or whale migrations. However, North America may have up to 18 migratory dragonfly species. A recent study revealed that the species undertakes complex long-distance migrations every year that span generations and seem to be influenced by temperature, making them particularly vulnerable to climate change.

Catfish have taste buds spread across their entire skin, making their whole body function like a tongue that can taste food several feet away.

Fruit fly experiments helped identify genes responsible for major body development

The insects' fast life cycle and affordability have allowed geneticists to quickly identify which genes are responsible for limbs, eyes, and other body structures by inducing mutations. The same genes may be responsible for different parts of a species' body, such as limb-building genes being responsible for wing pigmentation in butterflies.

Fruit fly sperm are gigantic—about 40 times larger than human sperm, according to scientific research published in June 2026.

Mosquitoes stop flying at wind speeds equivalent to the swishing of a horse's tail.

Fireflies light up to provide mating signals and warnings to predators

Variations in the illumination patterns and flight paths while emitting light have been observed across firefly species. Some species instead rely on pheromones if they are primarily active during the day or have lost the ability to illuminate.

Metamorphosis evolved over millions of years as species that hatched as smaller versions of adults started exhibiting genetic mutations that differentiated juvenile and adult bodies.

Why scientists are making robot insects

Insects have much to teach us about flying, jumping, moving quickly, and more. So, roboticists are studying how insects do the ridiculous things they do, like walk on water or jump fifty times their body height, to inform their design and engineering of a new slate of robots: tiny ones. Learn the future of this type of robot with this fascinating video with insights into both insects and robots.

At any given time, there are an estimated 10 quintillion individual insects alive on Earth.

Mosquitoes drink a maximum of 0.01 milliliters of blood in a single meal.

Some female fireflies mimic the signals of other species to lure in and eat them

The genus Photuris does not produce its own defensive pheromones to ward off predators, so it has developed mimicry to attract males of firefly species that do. Unsuspecting males are consumed after these chemicals—lucibufagins—are extracted.

What is it like to be a bee?

Scientists have long known the intimate features of bee anatomy: six limbs, five eyes, lots of hair, a long, tasteless tube -like tongue, and wings that stroke close to 12,000 times a minute. But getting inside the mind or consciousness of a...

Although many insects are colloquially referred to as bugs, insects are only considered true bugs if they possess a proboscis—a straw-like mouthpart that can pierce surfaces and suck up fluids.

Some mosquitoes are key pollinators—and eat disease-carrying mosquitoes.

Tracking butterfly migration via the pollen they collect

Trillions of insects migrate around the world each year, but many are too small to track with physical trackers, leaving their migratory routes a mystery. In recent years, scientists have utilized pollen grains collected from butterflies to analyze which plants that pollen originated from—providing substantial data to infer the insect's specific route. Research has shed light on many insects' migrations since, including the Painted Lady butterfly. Read more and see a map here.

The dragon has been central to Chinese culture since ancient times

One of the most recognizable symbols in Chinese culture, the dragon is known as a mighty yet often benevolent creature. The dragon is capable of interacting with gods in the heavens; it can turn invisible, shape-shift, and control the weather. These features made the mythological creature hugely significant to the Chinese people because if they could summon dragons, other aspects of their life could improve.

View some of the species named after David Attenborough

Acisoma attenboroughi is a dragonfly from Madagascar named in honor of Attenborough's 90th birthday. Stating they liked watching Attenborough's documentaries with their family, the discoverer of a flightless weevil from Indonesia named it Trigonopterus attenboroughi in 2014. A Peruvian frog was named Prisimantis attenboroughi in 2014 to honor Attenborough for raising awareness of wildlife conservation.

Spiders may manipulate captured male fireflies into mimicking female mating signals

Rather than killing a male firefly captured in its web, the Araneus ventricosus spider bites into it, which researchers believe injects a venom that disrupts normal flashing behavior and produces a form of mimicry to attract additional males. (Some readers may experience a paywall.)

Over 1,500 insect species pollinate plants in the UK

These insects—including bumblebees, moths, butterflies, and beetles—play a crucial role in the reproduction of flowering plants, also known as angiosperms. They do so by transferring pollen from the male reproductive organ—the anther—to the female one—the stigma—which enables the plant to produce fruit.

Watch insects and animal pollinators in slow motion

Mosquitoes top the ranking of the world's deadliest animals.

Mosquitoes are the world's deadliest animal, but gene drives could kill them.

Owls cannot move their eyes because they lack eyeballs, having instead developed cylinder-like tubes held in place by bones, which provide stability and lock visual focus when hunting prey.

About one-third of the world's food supply depends on pollinators like bees, butterflies, and bats to transfer pollen between flowers, which use bright colors, scents, and nectar to attract them.

Coevolution of pollinators and flowering plants diversified both

The first pollinators were beetles, which consumed pollen before flowering plants existed. Over time, plants evolved to attract more insects and improve the uptake of pollen, while insects adapted their biology to enhance the capture of pollen, such as developing specialized mouthparts.

Some dinosaurs evolved night vision and acute hearing for nocturnal hunting

Paleontologists analyzed the fossilized eye and ear structures of 16 theropods, finding that some had owl-like hearing and huge pupils. These characteristics are consistent with modern-day nocturnal species, including nightjars and geckos.

How snake biology allows them to eat prey larger than they are

Possessing flexible skulls with elastic ligaments and unfused jaw bones, snakes can open their mouths to engulf much larger prey, and adjustable airways enable them to continue breathing while their teeth grip onto their food. Through slow digestion and specialized cells that decompose bones, some snakes can survive on a single large meal for over a year.

Butterfly populations have declined by 22% from 2000 to 2020

Research suggests that one in every five butterflies is lost due to pesticide use, habitat loss, and climate change. Playing a vital role in pollination, their declining populations threaten plant reproduction and the health of ecosystems.

Fruit fly experiments show personality emerges, in part, from genetic factors

A 2025 study revealed that fruit flies exhibit unique behavioral preferences, akin to personalities, which could be artificially selected for when breeding to modify behavioral variability. This variability can be adaptive in unpredictable environments.

Bees evolved from meat-eating wasps that became vegetarian

After flowering plants first appeared approximately 140 million years ago, some wasp diets would have changed as they consumed pollen-coated insects that would visit these plants. Bees that branched from these wasp species also developed long tongues to slurp nectar and ultraviolet vision to identify flower patterns unseen by humans.

Biofluorescent animals—those that absorb light, such as ultraviolet rays, and re-emit other types of light, such as neon green—include some flying squirrels, scorpions, sea turtles, and platypuses.

Mosquito necroprinting uses an insect's mouthpart as the printer nozzle

Mosquitoes are abundant, and their nozzles are 32-100 times cheaper to harvest than to create from scratch out of metal or glass. By coating the organic nozzle to increase its strength, researchers are employing necroprinting to create tiny structures at better resolutions than commercial alternatives.

Snakes move around by coordinating hundreds of muscles

Mosquito saliva acts as an anticlotting agent

The bug's piercing mouthpart, the proboscis, is actually several tubes—one for sucking, one for spitting. But the chemicals in its spit actually help its blood meal to flow, combating its victim's ability to clot at the puncture site.

A Venus flytrap's hairs convert sensory touch into electrical signals

A stretch-activated ion channel called DmMSL10 acts as an amplifier, converting grazing contact into a strong impulse that the plant uses to react and close its jaw. To distinguish prey from raindrops or other stimuli, the jaw only closes when the hairs are touched twice in quick succession.

Chameleons change color by altering the spacing of nanocrystals under their skin, which changes what colors of light are absorbed and reflected.
