Discover strange facts about insects and arachnids: spiders, beetles, butterflies, ants, bees, mantises, dragonflies, scorpions, and the tiny creatures that...
Insects and arachnids make up the vast majority of animal life on Earth. With over a million described species and millions more awaiting discovery, they inhabit every continent and nearly every ecological niche. From the depths of caves to the canopy of rainforests, these arthropods shape the world in ways that most people never notice.
Bees and butterflies pollinate the crops we depend on. Ants engineer soil and recycle nutrients. Spiders keep pest populations in check without a single drop of pesticide. Beetles break down dead wood and return it to the earth. Without these small creatures, terrestrial ecosystems as we know them would collapse within decades.

Scientists have described roughly 1 million insect species so far, but estimates of the true total range from 5.5 million to over 10 million. Beetles alone account for about 400,000 known species, making Coleoptera the largest order in the animal kingdom. New species are described at a rate of about 7,000 per year, meaning most insects alive today have never been formally catalogued.
Bee populations are declining due to a combination of factors that researchers call the four Ps: pesticides (especially neonicotinoids that impair navigation and immunity), parasites (the Varroa destructor mite devastates honeybee colonies), pathogens (viral and fungal diseases spread rapidly in weakened hives), and poor nutrition caused by habitat loss and monoculture farming that reduces floral diversity. Climate change compounds these stressors by disrupting the timing between flower blooms and bee emergence.
Spiders produce silk in specialized abdominal glands called spinnerets. Inside these glands, large proteins called spidroins are stored as a liquid solution. As the spider pulls the liquid through a narrow duct, changes in pH, ion concentration, and physical shearing force cause the proteins to align and solidify into a fiber that is, pound for pound, stronger than steel and more elastic than nylon. Most spiders have multiple types of silk glands, each producing a different silk for webs, egg sacs, draglines, or prey wrapping.
The horned dung beetle (Onthophagus taurus) holds the record as the strongest insect relative to its body weight. Laboratory tests have shown it can pull 1,141 times its own body weight, the equivalent of a human pulling six double-decker buses. This extraordinary strength evolved through sexual selection: males use their horns to fight rivals inside tunnels for access to females, and only the strongest males reproduce successfully.
The question remains scientifically debated. Insects possess nociceptors, sensory neurons that detect harmful stimuli, and they exhibit protective behaviors such as limping after leg injury or avoiding locations where they previously received a shock. However, whether these responses constitute the subjective experience of pain or are purely reflexive remains unresolved. Recent research on fruit flies and bees suggests more complex processing than simple reflexes, but consensus on insect sentience has not been reached.
Ants are among the most successful animals on Earth because of eusociality: a division of labor where queens reproduce, workers forage and build, and soldiers defend. This cooperative structure lets a colony function like a superorganism that can exploit resources far more efficiently than any solitary insect. Combined with chemical communication through pheromones, the ability to farm fungi and herd aphids, and adaptability to nearly every terrestrial habitat, ants have colonized every continent except Antarctica and make up an estimated 15 to 20 percent of terrestrial animal biomass.
The Brazilian wandering spider (Phoneutria) is widely regarded as the most dangerous spider to humans. Unlike most spiders that avoid contact, wandering spiders are aggressive, highly venomous, and often found in populated areas, sometimes hiding in banana shipments. Their venom contains a potent neurotoxin that can cause severe pain, paralysis, and in rare untreated cases, death. The Sydney funnel-web spider (Atrax robustus) is another contender, with venom that is particularly lethal to primates, though effective antivenoms have made fatalities rare in Australia since 1981.
