Bugs & Insects Facts for Kids
Creepy-crawly facts about insects and bugs
Spiders don't have extensor muscles in their legs — instead they extend them by pumping fluid into them hydraulically. When a spider dies, its legs curl inward because the hydraulic pressure is lost.
The black fire beetle can detect forest fires from 80 km away using infrared sensors on its body — it seeks out freshly burned trees to lay its eggs where competition is reduced.
The Sydney funnel-web spider has a venom so potent it can kill a human within 15 minutes — but an antivenom developed in 1981 means no one has died from a confirmed bite since then.
Mole crickets tunnel Y-shaped burrows carefully designed to amplify their calls like a megaphone — the dimensions are tuned to the frequency of their own song to maximise broadcast distance.
Leaf-cutter ants carry bacteria on their bodies that produce antibiotics to protect their fungus gardens from harmful moulds — scientists are studying these bacteria for new antibiotic compounds.
Female fig wasps crawl inside figs through a tiny opening to lay eggs, often losing their wings in the process — as they move around inside, they pollinate the fig's flowers.
The drone fly larva, nicknamed a rat-tailed maggot, lives in stagnant water and breathes through a telescoping tail tube up to 15 cm long that extends to the water surface like a snorkel.
Unlike mosquitoes that pierce skin, horse flies have scissor-like mouthparts that slice skin open and lap up the blood — their bites cause more pain but are less likely to transmit disease.
Maggots of certain blow fly species are used in medicine to clean infected wounds — they eat only dead tissue, leaving healthy tissue intact, and secrete antimicrobial compounds.
Potter wasps construct tiny clay pots that look like miniature vases — they fill each pot with a paralysed caterpillar as food for their larva, lay an egg, then seal the pot with a clay lid.
