No matter your opinion on them, insects are an integral part of our world and a fascinating topic for teaching purposes. Many educators utilize insect models in classroom lessons as an introduction to science.
1. They have brains
One of the more surprising facts about insects is their brain is relatively large for such tiny organisms! Their protocerebrum brain, responsible for memory and learning, also connects to their antenna to gather information on taste, scent and sound.
Insects possess numerous “little” brains throughout their bodies that aid them in performing tasks not controlled by the central brain. These “ganglia” are similar to nerve bundles found in your arm, thigh or head; one such ganglia in an insect’s abdomen even continues to function after losing its head; hence why praying mantis can continue functioning without its head!
But one of the most amazing characteristics of insects is their remarkable capacity for adaptation, evidenced in their behavior, anatomy and color patterns. For instance, beetles can survive long submersion in water by holding themselves upside-down and collecting air via their abdomen that serves as a breathing tube. Communication among ants within a colony occurs through chemical signals transmitted by their queen and then disseminated throughout. By doing this, she can warn her troops for an impending attack or even kill any enemy intruders who enter her territory. Ants exhibit impressive intelligence and make fascinating displays like this, showing us how a small brain can assist a larger system in making wise decisions. That explains how so many insect species have survived across diverse habitats from mountain ranges covered with snow to scorching deserts on Earth.
2. They feel pain
One of the fascinating insect facts is that insects feel pain. While many might dismiss the possibility, multiple studies have confirmed this fact; for instance, one found a fly with an illness flew around panicked and behaving as though dying!
Insects possess nerve cords with descending neurons that stimulate defensive behaviors when they’re injured. For example, tobacco hornworms squirm and shake their bodies when feeling needle pricks or the touch of leaves touching their bodies, grooming themselves to remove debris that may have caused injury and also grooming themselves to remove any potential debris that caused injury.
Researchers have studied the behavior of ants with crushed legs and found they continue to behave normally, though this doesn’t imply they don’t feel pain; it could just be that their normal response to injury has been suppressed; this also happens with humans when we continue fighting after receiving life-threatening wounds.
Some insects even kill themselves to relieve themselves of pain – this is known as self-deprecation. For instance, certain ant species (like the Exploding Ant) will split their skin open to release yellow goo and divert enemy attention away from their colony – this practice of self sacrifice is one of many fascinating bug facts!
Insects are fascinating creatures. From their amazing mating rituals to how cricket chirps can forecast weather changes, insects offer many fascinating behaviors and are vital components of our world. With 20 startling facts about insects you’ll be amazed at just what six-legged creatures can do!
3. They have ears
Insects are one of the world’s most diverse groups of animals, boasting over 10 quintillion species in existence. Yet some aspects remain universal among them all – all insects possess a head, thorax and abdomen covered by an exoskeleton and three pairs of legs; furthermore they possess antennae, compound eyes and may even possess ears (Live Science).
Ears are composed of chordotonal organs found throughout an insect’s body and modified so they function like ears; these sensory cells help the insect detect sound vibrations necessary for locomotion as well as serve as proprioceptors – sensors which allow insects to sense their position in space.
An insect’s ears may not be readily apparent; they’re located on either side of its head and used to detect all manner of sounds ranging from insects moving nearby to crickets or birds nearby; their ears can even detect soundwaves that penetrate its exoskeleton and penetrate their senses.
An insect’s ears provide an excellent example of “one-part-many-functions”, or multifunctionality. Their ears act as receptors for near-field sounds while their antennae contain highly specialized sensory cells that detect far-field sounds as well as particle movements caused by vibrations.
Although most of us may recognize that bugs can fly, not everyone understands why and how they do so. Some insects can fly for long distances while others have learned to walk on water or build houses made out of glass. Other notable facts about insects include termites’ ability to hear heavy metal music which makes them chew more effectively on wood.
4. They have webs
Though we often associate insects as fragile and small creatures, some parts of their bodies can actually be quite strong and durable. Their wings, for instance, are composed of cuticle material – the second toughest natural material known to humanity – meaning if one breaks, they must live with it until it heals – usually successfully!
Another impressive fact about bugs is their remarkable ability to breathe underwater, thanks to an organ on their abdomen similar to a snorkel. Gerridae insects are great examples of this, while other bugs that can walk across water’s surface include titan beetles (with up to seven inch jaws and huge mouthparts), double drummer cicada’s (known as loudest insect in the world), and double drummer cicadas – which has the loudest insect sound worldwide!
Not only can insects breathe, they have ears that can detect vibrations. Some insects, like tachinid flies, feature ears protruding from their necks while crickets and katydids possess sound-sensitive membranes on their legs that enable them to hear buzzing of other insects through these membranes.
5. They fly
Most people don’t think of bugs as superflying flying superheroes; when June beetles crash against their windows or mosquitoes buzz near blood-engorged ears, most will likely want to swat them away rather than admire them. Yet for scientists studying insect flight, these tiny creatures are amazing feats of engineering.
Attractively shaped wings help insects generate lift by rotating in an oval fore-and-aft arc similar to that of a helicopter blade, flipping their wings over at the end of every stroke to form a leading edge vortex and help create smooth and powerful flight, while simultaneously decreasing drag — an issue especially pertinent when creatures flap their wings 200 times per second!
Insects are among the most diverse animals on Earth and can be found almost everywhere. Their class, Insecta, includes ants, bees, flies and beetles with three body segments (head, thorax and abdomen) connected by two pairs of wings – making insects an amazing group of organisms! Their hard exoskeletons, compound eyes and three legs make them highly versatile creatures.
Exploding ants of the Order Formicidae insect family sacrifice themselves when their colonies are attacked by enemies by splitting open and spraying a yellow goo all over themselves – this self-sacrifice being an essential component of their survival strategy.
Other insects display equally impressive abilities. Elytra sylvestris leaf bugs have one of nature’s most amazing camouflage techniques: rocking back and forth like leaves being blown by the wind to fool predators into believing they’re real plants. Meanwhile, termites use vibrations from heavy metal music to accelerate their chewing speed, chewing through wood faster.
