Up to 20 species of hornets live on Earth. Some of them are large and dangerous to humans. The largest hornet is the Asian giant hornet. Its body is up to 5 cm long, its wingspan is up to 7.5 cm, and its weight is up to 200 g.
This insect is so large that during flight it can be mistaken for a bird, therefore it is called a sparrow bee. The bites of giant hornets are poisonous, so people are better off staying away from the nests of these creatures.
The most common and largest are four types of hornets. Topping their rating is the Asian killer hornet.
Blister beetle
This beetle is known to the world as a locust exterminator. A lot of benefits come from it for vegetable gardens and crops. It is common in the southern and southeastern parts of our country. It is dangerous for people with its protective secretions, which can leave extremely painful blisters.
If the poison of this insect gets inside the body, then the harm can be irreparable, especially for young children. In ancient times, quite a few people from noble families were poisoned by the poison of this insect.
Brazilian wandering spider
If you intend to travel to Brazil, please skip this paragraph. The Brazilian wandering spider, also called the banana spider, has entered the Guinness Book of Records as the most venomous spider. Found in the tropics of South and Central America. Spider venom contains a powerful neurotoxin that acts on muscles. A person cannot control muscle activity, which ultimately leads to respiratory arrest and paralysis. The ingress of poison into the blood in 85% of cases leads to death. The only good news is that the antidote has long been found, the main thing is to go to the hospital on time.
Asian killer hornet
Even in the middle lane there are hornets. Their bites are extremely painful and can send you to a hospital bed for a couple of weeks. If the bite hits the neck, death can occur. As for the killer hornet, the name of the insect speaks for itself.
First, such a hornet is huge. Its gigantic size is frightening and makes most people tremble with fear. It is about 5-6 centimeters long. Its bite can be fatal. In addition, it is incredibly painful, because the sting of this insect reaches more than half a centimeter in length. Those who are "lucky" to feel the bite of this "monster" note that it is unlike any other pain. It penetrates to the bone. If you get bitten, it can attract other hornets, so it's best to run.
3) African siafu ants
One colony of these ants, which consists of 20 million individuals, can devastate an entire African village, sweeping away everything in its path. When there is not enough food, the siafu colony begins to eat whatever it comes across in order to somehow survive. Ants can kill animals and humans and cause thousands of dollars in damage annually as they destroy valuable food supplies to Africa.
Usually nesting in sand or soil, fire ants build rather tall anthills, feed mainly on plant food, sometimes on crickets and small insects. If disturbed, they can sting painfully, and their bite is similar to the sensation of a burn, hence the name. Small bites of one or two ants can be easily and quickly cured, but if you are attacked by a whole family of angry ants, expect trouble.These ants are reported to kill up to 150 people daily and also harm crops.

Bumblebee
In childhood, adults told many of us that the bumblebee does not bite, that he is kind and should not be afraid of him. This is partly true, because this insect stings incredibly rarely. On the other hand, if it stings, it will lead to very unpleasant consequences. The bumblebee bite is quite painful, and it can be repeated, because this insect does not lose its sting.
One case in a hundred can lead to serious consequences in the form of loss of consciousness. The cause is an allergic reaction to bumblebee venom. If he bites you in the face, then the swelling may not go away until 2-3 days.
Caterpillar Lonomia
This colorful caterpillar lives in the forests of South America. Locals call her the Lazy Clown, but this nickname does not fully reflect the insect's danger. It is enough just to touch the caterpillar to receive a portion of the poison, which serves to protect against predators. For humans, it is also dangerous: poison causes kidney failure, destruction of red blood cells, hemorrhagic bleeding. The severity of the symptoms depends on the duration of the touch - if it lasted only a few seconds, the chance of survival is quite high. But if a person is faced with several lonomies at once, then a lethal outcome is very likely.
Lonomia is difficult to detect - the natural color helps the caterpillars to camouflage well in the forest.
Wasp
Wasps can fly alone, or they can be in a certain place in a whole flock. They are not as aggressive as some bees or hornets, but will sting easily if a person smells of sweat or waves their hands. A wasp sting is toxic, but not particularly dangerous. More terrible for humans is that wasps carry various diseases.
There are cases when, after a wasp bite, a person became infected with intestinal diseases of varying severity. This insect is far from the most pleasant insect, because it looks for food everywhere - in garbage dumps and in terribly dirty places.
Green (carrion)
Despite its indifference to all kinds of carrion and sewage, this fly is a very beautiful insect with a glossy emerald body and translucent smoky wings with a weakly expressed openwork pattern. Its body length is about 8 mm. The fly's eyes are large, reddish, the abdomen is rounded, the cheeks are white. Green flies live mainly in dirty places.: on decaying animal carcasses, in manure, waste, - but sometimes they can
meet among flowering plants with a strong aroma. They feed on organic decaying substances, where they lay their eggs.
After mating, the female lays about 180 eggs. The egg has a grayish or light yellow tint. She tries to hide them as deep as possible in carrion, where they develop for 6–48 hours to the larval stage. The body length of the larva varies from 10 to 14 mm. After 3–9 days, they leave their habitat and move to pupate in the soil. The pupal stage lasts from 10 to 17 days (depending on weather conditions), after which the insect climbs to the surface already in the form of an adult fly.
Bees
Another representative of the "biting". Bees are a noble insect that gives us honey, pollinates plants. Beekeeping is very common in our country, so in some villages and villages you can stumble upon a large number of these little hard workers.
If you are near the hive and the bees do not like your smell or one of them has bitten you, then it is better to run as quickly and further as possible. When a whole hive rises, it is worse than any attack. Of course, bees are pure insects, but they stand up for each other and protect the queen at the cost of their lives.
Second place - ground beetle
A meeting with a ground beetle is associated with a special risk - and this is not in vain.A large black beetle may interest a child or be close to an adult, and interest in him may end in failure. The beetle is able to shoot corrosive liquid from the back, and at a considerable distance, up to 50 cm. If the substance gets on the skin, there will be a burning sensation and discomfort. In case of contact with eyes, mouth, respiratory organs, the risk increases; it is necessary to rinse the affected surface with plenty of water.
Gadfly
It is a scary insect because the consequences of its interaction with humans can be catastrophic. Gadflies are similar to horseflies, but they are larger, shaggy and have a disproportionately large head. Their larvae are dangerous, not themselves. Larvae live inside a living organism - for example, a human. Often they can be picked up on the grass, but there are species of gadflies that shoot a larva on the fly, aiming at the eyes.
The gadfly can enter both the abdominal cavity and the brain. If nothing is done in time, there is a risk of death. The presence of a gadfly larva in the body becomes clear after the appearance of vomiting, fever, blue discoloration at the site of the bite.
Room
The fly belonging to this species practically does not live in the wild. Therefore, she is the most annoying and impudent guest in our homes in the summer-autumn period. At this time, our life is complicated by the constant struggle with these small, but very fast and dodgy insects.
Houseflies are most active during the daytime. The homeland of this insect is the steppe of Central Asia. But at the moment, its spread is observed everywhere near a person's dwelling - both in rural areas and in cities.
A fly of this species is not a biting and blood-sucking insect, but nevertheless it causes significant harm to humans. Its limbs have tentacles on which various harmful bacteria and dirt collect, leading to infectious diseases.
The body of a housefly is gray with brown tints. It consists of an abdomen, head and chest. The chest is connected with wings and three pairs of legs. On the head are very large eyes, which occupy almost the entire head, the oral cavity and short antennae. The upper part of the breast with four dark stripes, the belly with black spots in the form of quadrangles. The lower half of the head is yellow. The total body length of a fly usually does not exceed 8 mm. Males by size
there are fewer females.
In the female, the frontal part of the head is wider, and the distance between the eyes is greater than in the male. The flight of a fly is carried out only with the help of two front membranous transparent wings, and the rear ones (halteres) are necessary only to maintain balance.
In appearance, many species of flies are similar to the house fly, but its distinguishing feature is the vein that forms a break in front of the edge of the wing. The limbs of the housefly are thin and long with suction cups for easy movement over various surfaces. These suction cups allow it to move freely even on a vertical glass plane and on the ceiling. The fly's speed is very high and it can last for several hours.
Food
Despite the small antennae, the sense of smell in the housefly is heightened. She is able to smell the smell of food at long distances.
Her mouth organs are not capable of biting - they only have a licking-sucking function. For this, the fly has a flexible proboscis on its head, with the help of which it not only sucks liquid food, but also absorbs solid food. The fact is that the fly secretes saliva, which dissolves solids.
Reproduction and development
The favorite place for laying eggs for the housefly is rotting moist environments such as manure and various sewage. Having chosen a suitable place, the female lays from 70 to 120 white eggs, the length of which is about 1.2 mm.The stage of transition from egg to larva, depending on environmental conditions, lasts for 8-50 hours. The larva is an elongated white body without limbs, similar to a small worm 10–13 mm long, with a pointed head. She continues to live in the stool of various farm animals (horses, chickens, cows).
After the larva has 3 molts, after 3–25 days, its shell hardens and separates from the body. Thus, it becomes a pupa and after 3 days it turns into a young fly, which can produce offspring in 36 hours. The average lifespan of a housefly is 0.5–1 months, but sometimes, under particularly favorable conditions, it can survive up to two months. The female is capable of laying eggs up to 15 times in her entire life. Depending on the air temperature and other climatic factors, the total number of offspring ranges from 600 to 9,000 eggs. The breeding season of the housefly lasts from mid-April to the second half of September.
Cockroach
Cockroaches themselves are harmless, albeit disgusting. It's scary what they can bring with them. We are talking about encephalitis, intestinal viruses, parasites. If there are a lot of cockroaches in the house, there is a risk of contracting something dangerous and very unpleasant.
This is one of the nastiest insects that can exist. Their mere sight is nauseating, so they can be called the worst nightmare of any room.
Conclusions and advice
As you can see from the description of this small species, we can conclude that very poisonous insects live around us. Meeting with them can turn out to be deplorable for us. Russia, with the wealth of its geographic latitudes, is a haven for the most dangerous and poisonous insects. As a rule, we meet with them while relaxing in nature.
The most important rules of conduct should be remembered:
- on vacation, be careful, if poisonous insects are found, leave the place;
- wear protective clothing (anti-mosquito, anti-mite clothing);
- treat open areas of the skin with special aerosols and ointments;
- if you feel a bite or find a bite site, treat the wound with antiseptics and see a doctor.
Remember! Only the most careful and correct actions will reduce the chances of being bitten by poisonous insects.
Mite
Ticks carry a very dangerous disease - encephalitis. This insect is very unpleasant in that it is very difficult to notice it even after it has sucked on to a person. At the same time, it is advisable not to do anything on your own, but to immediately go to the doctor so that you are checked for diseases and the insect got out correctly.
Ticks live in grass and trees, so in the forest in central Russia you always need to cover yourself with something. Ticks can enter the ears, bite the head and other parts of the body. Children are most susceptible to this. Be as careful as possible in the forest and parks.
Each of the above described insects is dangerous to humans. They are unpleasant because they are small, and many can fly. They are elusive, almost invisible, but very scary. We wish you never to be bitten by these creatures.

Tsetse fly
Inhabitants of tropical and subtropical Africa, when bitten by an animal or person, infect him with sleeping sickness caused by parasites trypanosomes.
They attack everything that moves, but it's interesting, but the only animal that this poisonous fly does not bite is zebras. Scientists say that the Tsetse eye perceives this animal only as a series of moving black and white stripes, not perceiving zebras as a victim.
Despite the struggle, in the arid African climate, Tsetse is rapidly recovering its population.
So the top of the most poisonous insects on planet Earth from TopCafe.su has been completed.Science is developing, and it is possible that in the future entomologists will present to the world new and most dangerous species of flying, crawling, jumping insects.
But in any case, a careful attitude to nature and adherence to basic safety standards will save you from many problems associated with communicating with wildlife.
What do insects threaten
Nature never ceases to amaze people with the wonders of flora and fauna. Not only are beetles sometimes very unpleasant looking, but they can also be deadly to others. How does the threat manifest:
- insects become carriers of infection;
- the creature poisons the victim's blood with poison upon close contact.
The study of insects is the science of entomology. The individuals themselves received the name "insects", thanks to Karl Linnaeus, the author of the animal classification system.
Kissing bug
Bedbug got a romantic adjective to its name for a disgusting addiction. He is attracted by human lips during sleep. The kissing bug senses the exhaled carbon dioxide. When bitten, transmission of a nasty parasite that causes Chagas infectious disease is possible. Many people infected with the kissing bug develop heart failure for ten years, the cause of which is the products of the parasite's poisonous waste inside the human body. More than ten thousand people die from Chagas disease every year.
Army ant
Army ants live in colonies, the number of which is simply enormous. The army ants are friendly and organized. Due to their blindness and aggressiveness, they attack even a huge victim, such as a horse. It is generally better for a person not to get in the way of army ants. No wonder they are considered one of the most dangerous insects in the world. Ants are constantly moving.
Karakurt
Karakurt is an insect that looks very cute, but it was not there. The insect looks like a ladybug, only larger. But only bites of females are fatal, both for humans and animals. But not every animal can kill this insect.
This spider lives in the steppes and close to water, so you need to be careful when going to the seas and to the Arkhangelsk region. The poison of the insect is second only to the venom of the black widow.
