Interesting facts from the life of insects abstract. Interesting facts from the life of insects

We don’t know about you, but somehow we don’t really like various insects: the buzzing of flies, mosquito bites .... Brrr... It's just awful. We are generally silent about cockroaches. But despite our hostility, insects sometimes show interesting abilities that any person would envy.

cockroaches

Probably the most disliked insects in our country are cockroaches. But despite the general hatred towards them, they are the most powerful. When the Americans dropped nuclear bombs on the Japanese cities of Nagasaki and Hiroshima, the only surviving insects were cockroaches, although they will still die when exposed to 100,000 units of radon. But the ability to survive where it is deadly for an ordinary person is not the only plus of these vile creatures. More recently, scientists have discovered that cockroach brains contain 9 antibiotic molecules that protect them from deadly bacteria. Through laboratory tests, scientists realized that these nine molecules could help us fight disease far more powerfully than any antibiotic we use to treat disease. Perhaps very soon, cockroach molecules will help us get a cure for methicillin-resistant staphylococcus aureus, a bacterial infection that is more dangerous than E. coli and AIDS.

Fleas

Despite the fact that fleas are harmful to your beloved pets, they have something that deserves admiration: they are able to jump 150 times their height. For example, if you are 175 centimeters tall and you were a flea, you could jump 263 meters.

bees

The most intelligent insects in the world are bees, which can not only communicate with each other (with the help of their “waggling dance”: making movements with their bodies, they tell other bees where they are). the best place to create a colony or arrange food), but they also know that our planet is round. They take this fact into account when determining the location of the food source. In addition, they can easily calculate the angles by simply reading the data of their waggle dance. And they also use the position of the sun for orientation, as well as various landmarks and the electromagnetic field of our planet.

dragonflies

Unlike many animals, humans have the ability to selectively focus. Right now you are manifesting this ability to eliminate various factors distracting you from reading this article. It turns out that in addition to humans and primates, dragonflies also have this ability. If, for example, she sees a swarm of tiny insects, she is able to focus on only one individual. When it comes to catching prey, dragonflies are second to none and their success rate is ninety-seven percent!

locust

Locusts can be called the best pilots in the world of insects. They can fly long distances while expending a minimum of energy. In addition, while flying, locusts can twist their wings to control the amount of flapping they make. This helps them maintain a constant flight speed. So that they can easily fly up to eighty kilometers without rest.

bombardier beetle

But the most the best insect with a defensive strategy is the bombardier beetle. He is able to fire his hot mixture of chemical solution so hard that he easily maims his enemies. The temperature of its toxic mixture reaches one hundred degrees Celsius. But the most amazing thing about this beetle is the structure of its body. He fires a mixture of hydroquinone and hydrogen peroxide at his enemies. If not properly stored and mixed properly, these chemical substances capable of literally blowing up a bombardier beetle. But due to the presence of two glands in the abdominal cavity, he separates hydroquinone from hydrogen peroxide and mixes them only in a certain part of his body. The result of this proper blending is its toxic defense that inflicts fatal wounds on the enemies of the bombardier beetle.

Fireflies

We all know about the amazing ability of fireflies to produce their own light. But besides this, humanity can learn from them how to use energy efficiently. The nature of fireflies is so amazing that it allows them to use energy without losing much of it to heat. For example, the electric lamps we use at home use ninety percent of their energy for heat, and only 10% for light production. The firefly's body uses one hundred percent of the energy to generate light. In addition, these wonderful insects can communicate with each other using different kind flicker.

Ants

We all know about the industriousness of ants, but besides that, they also have an amazing ability to always find their way home. They do this with the help of various visual cues, and in places where there are none (for example, in the desert), they additionally use their super-sense of smell. They seem to smell in stereo, that is, they can distinguish simultaneously two different smells coming from different places. With the help of this super ability, they create their own scent map and easily find their way to their anthill.

wasp riders

Wasp riders get their name from the fact that they can literally turn their prey or prey into "zombies". They lay their larvae in the bodies of young moth caterpillars. The larvae live inside the caterpillars, feeding on their bodily fluids. And when the wasp larvae are fully formed, they leave the body of their victim and create a cocoon, which is attached to a branch or leaf. At the same time, the caterpillar does not leave the cocoon, but remains nearby and acts as a bodyguard, protecting the wasp from various predators.

dung beetles

Dung beetles made our list of superbugs thanks to astronomy and feces. All due to the fact that dung beetles lead a disgusting lifestyle: they collect other people's feces and roll them into a ball. They use this ball as a source of food, in the form of a house, or lay their eggs in them. But the amazing thing is that they can roll a ball of dung exactly in a straight line even at night. This happens because they are guided by the stars. Conclusion: Dung beetles are great processors and incredible astronomers.

For most urban children, the village is a living museum of nature, much more interesting and instructive than all the "adult" expositions put together. After all, there are so many interesting, unknown and mysterious things in the countryside! First of all, it is worth paying the attention of children to insects from the “inner environment”. These are ladybugs, caterpillars, butterflies, grasshoppers. We got used to their presence and almost stopped noticing them, and children will be happy to listen to stories about the everyday life of these funny creatures. Watching insects, the baby will not only acquire new knowledge, but also learn to think, analyze, compare, reason.

10 interesting facts about insects:

1. All insects have common features: six legs, antennae and wings. Their body is, as it were, divided into parts by thin lines - notches. Hence the name "insects".

2. Ladybug is of great benefit: it destroys many plant pests - aphids. Ladybug is cunning - she can pretend to be dead if you put her on the palm of your hand. The ladybug at the first danger releases a yellow liquid - even if the bird once grabs ladybug, then he will understand that this bug is tasteless, remember its color and will not touch it again.

3. Why is it said that the grasshopper plays the violin? The fact is that on his wings there are special notches. He rubs them quickly, quickly, one against the other, as if he were running a violin with a bow, and a chirring is heard. Let the kid properly examine the grasshopper (what color is it, does it have antennae and eyes), and at the same time think about why it needs such long hind legs. Of course, to jump!

4. Bees, bumblebees and wasps are pollinating insects. Indeed, without them, flowers would never have become fruits, which means that we would not be able to enjoy delicious apples.

6. Ant is the strongest on earth! He can carry loads 10 times heavier than his own weight. If adults do not forget to take a magnifying glass to the dacha, with its help the kids will learn a lot of interesting things about the life of these ubiquitous ants. To do this, it is enough to find a small anthill with holes-doors in the ground and from time to time observe it: what do the ants do, how they treat each other, what prey they drag, how far do they run away from their home?

7. The main pest for country garden - Colorado beetle, regularly "attacking" the potatoes. The child needs to be told about the harm this insect causes, and asked to help in the fight against it. Usually, children do a good job of this task, collecting bugs in a jar of water, while training their fingers.

8. At night, it is interesting to follow the fireflies. The firefly flies in zigzags. Be sure to show with your hand in the air how the firefly flies. In the dark, the firefly glows with a yellowish light.

9. Bees collect nectar from which they make honey. The bee collects nectar with its proboscis. Bees have a whole set of tools on their legs. Here you will see brushes for collecting pollen, and baskets for transferring pollen, and brushes with which bees clean their eyes from pollen that has fallen into them. Bees, flying, buzz: "zh-zh-zh-zh-zh-zh-zh". Play bees with your child: repeating this sound is good for speech development.

In impenetrable forests and jungles, new species are still discovered from time to time, which amaze scientists, and already known ones sometimes change under the influence of external environment. Evolutionary processes do not stop, it’s just that it is far from always possible to trace the changes caused by them over several generations.
