This species lives in Burma, India, China, Korea, Thailand and Japan. There are very few of them in Russia, so much so that they are listed in the Red Book of the Trans-Baikal Territory. In addition, sometimes such hornets are found in the Primorsky Territory and the Amur Region.
Interesting fact: despite their apparent small numbers and rare human encounters with them, black hornets are not an endangered species. Simply because of the peculiarities of their biology, they are not perceived by people as widespread insects, including in their main areas of residence.
What to do if bitten by a hornet
If you have been bitten by a hornet, you must immediately take the following measures:
- Take an antihistamine, for example, Suprastin, as quickly as possible; it will slow down the occurrence of an allergic reaction.
- You can try to suck out the poison released by the hornet from the wound, but you need to do this very quickly, since the skin at the site of the bite begins to tighten and if you missed 1-2 minutes after the bite, then there is no point in doing this.
- It is worth putting a cold compress on the bite site; it will slow down the spread of the poison and at the same time reduce swelling of the skin.
- Apply Fenistil gel to the bite area.
- If you have a fever after being bitten, do not bring it down unless it rises above 38 C.
- Do not drink alcohol under any circumstances.
- If you feel worse, do not hesitate to call an ambulance.
Mosquito and midge bites
Mosquitoes are temporary ectoparasites. That is, only females bite us during the breeding season. The rest of the time, like males, mosquitoes feed on flower nectar. The reaction to a mosquito bite is caused by an anticoagulant, a substance secreted by the female when she pierces the skin. It prevents our blood from clotting during absorption. A single puncture does not pose any danger; mosquitoes, like midges, are dangerous in numbers. And if the body of an adult copes in most cases, then the body of a child, which is not yet formed and weakened, can react violently to bites. More detailed information on how to protect yourself and how to treat them if you are bitten: mosquitoes and midges.
A giant among wasps - the Asian hornet
The largest wasp is Vespa mandarinia, also known as the Asian hornet. It should not be surprising that the title went to the hornet. This insect is a representative of the family of True wasps. Lives in the Middle Kingdom, Japan, Korea. Numerous populations occur in the Primorsky Krai in Russia.
Appearance
The largest wasp in the world reaches 5.9 cm in length, and the wingspan is 7.5 cm. If you sit such an individual on the palm of your hand, the wings will completely cover its surface. It is not for nothing that nature has awarded this species with its impressive size.
What does an insect look like:
- body color varies from rich yellow tones to moderate brown with characteristic black wide stripes and is determined by the subspecies;
- yellow head;
- cephalothorax in black tones;
- on both sides of the head there are huge teardrop-shaped eyes of almost black color;
- In the center of the forehead in the form of a triangle there are 3 additional simple eyes that allow you to distinguish between dark and light tones and help you navigate in space.
Lifestyle
Giant wasps live mainly in forests near bodies of water. The queen hornet is in charge of arranging the new nest, which is typical for all insects of this order. After waking up in the spring, she begins preparing a home for her future family. The female prepares building materials from chewed tree bark, abundantly moistened with saliva. She builds cells from a sticky substance in a very interesting way: she grabs the substrate with her front jaws, presses it tightly to her chest and, biting off a small piece, sticks it.
While the queen maintains her status as a “single mother,” she has to independently prepare food for the larvae. To do this, she is forced to hunt insects and deliver food to the cells. As soon as the working individuals emerge from the first eggs, the queen relinquishes all authority to arrange housing, prepare food, and is only concerned with the reproduction of offspring.
From morning to night, working hornets obtain food for the voracious larvae, whose diet must be enriched with protein foods. Therefore, giant wasps often raid apiaries and can completely destroy an entire family.
Killer wasps absorb honey, and the killed individuals are taken to the nest to feed the babies. It is worth noting that insects use their giant stings in extreme cases. They effortlessly cope with weak opponents using their developed jaws. It is difficult for beekeepers to resist the powerful force of wasp aggressors, so when they discover a hornet nest, they try to destroy it immediately.
Closer to autumn, population growth stops. The males die off after mating, and the fertilized queen looks for a new wintering place to start a new family next year.
How dangerous are giant wasps for humans?
Careless and ignorant tourists, having seen the largest wasp in the world, try to photograph it. The insect perceives this as aggression and attacks the person. There is no need to worry about the life of the wasp - in a split second it will remove its sting and go on about its business.
But the condition of the victim can be alarming, especially if there are a lot of bites. The only good news is that the wasp is a thrifty creature and uses the poison very sparingly. During one bite, she injects about 2 mg. The poisonous mixture contains many toxic components, as well as a potent poison - mandarotoxin. The sting of a huge wasp is painful and is comparable to piercing the skin with a hot nail.
The following symptoms may appear:
- the appearance of redness, extensive swelling;
- changes in blood pressure;
- cardiopalmus;
- headache;
- cramp, severe pain in the affected area.
First aid for a victim of an Asian hornet before the doctor arrives is to remove the sting if it is accidentally left, disinfect the affected area and apply a cold compress to relieve pain, burning and reduce swelling.
Benefits and harms
Why is this beautiful bumblebee dangerous? Male purple carpenter bumblebees lack the ability to sting, although they can pursue intruders into their territory. A female bee can sting, but it will not attack for no reason; in most cases, it will simply fly away when it sees a person. Solitary tree bees as a species are characterized by a low level of aggression, in contrast to honey bees (medium level of aggression), or wasps (high). The black bumblebee is no exception.
The sting of a black carpenter bee is painful and dangerous. Severe pain is felt at the site of the lesion, the skin turns red and swells. Insect venom contains substances that affect the human nervous system, so serious problems are possible for people with neurological diseases. Extremely negative consequences are likely for people suffering from allergies.
Could this bee attack lead to death? A carpenter bee sting to the throat can actually be fatal due to anaphylactic shock. However, the insect is an endangered species and, due to its calm disposition, rarely bites. Therefore, the likelihood of being harmed by a purple carpenter bumblebee is extremely low.
Carpenter bumblebees are sometimes considered pests that damage wooden buildings. But insects never choose fresh, strong wood for their nests. It is beyond their strength, despite their powerful jaws. Carpenters settle only in old wood that has lost a significant portion of its density. Therefore, their settlements can be considered an indicator of the quality of fences or sheds: if a carpenter bee begins to build masonry in them, then it’s time to update the material.
Carpenter bees do not live in painted or treated wood. The purple carpenter bumblebee is an excellent pollinator. In solitary bees this figure is many times higher. They work even in bad weather and are able to cover vast distances in search of food.
Mimicry
As already mentioned, syrphids are very similar in appearance to stinging insects - wasps, bees, bumblebees. The hoverflies seem to be camouflaged as them, and their striped black and yellow coloring helps them in this. But upon closer examination, you can notice the difference:
- syrphids have much shorter antennae (for example, a wasp has antennae up to 1 cm);
- they are smaller than wasps, bees, etc. (excluding especially large species);
- they have 1 pair of wings, while the stinging ones have 2.
But even with these minor differences, nothing prevents syrphids from feeling quite at ease and boldly in nature: their external imitation (mimicry, from the English word mimicry - disguise, imitation) of dangerous stinging insects is so believable that few birds risk attacking them, especially if you have already had a sad experience of contact with a wasp. But all this is despite the absolute harmlessness and even some defenselessness of the syrphids.
Nature has endowed these flies with such a coloring, thanks to which they may not be afraid of attacks from enemies. Hence several more popular names for hoverflies: bee-eater, wasp-fly, wasp fly, etc.
There is one unusual insect that appears in May. Everything about it is unusual: its appearance, as if stolen from a bumblebee, but with a long proboscis, and its flight style, with hovering in the air in one place, like a hummingbird, and even its name - Big Buzzer
, with three letters “F” in the name, in Latin Bombylius major. Flying from flower to flower and diligently collecting nectar, this shaggy miracle causes delight in everyone who manages to see it.
The body is short, slightly flattened, densely covered with hairs. The wings, the front of which are painted dark, are spread out to the sides, like a jet plane. The comparison with an airplane is all the more true since these flies (as well as hoverflies) are excellent flyers. The buzzer is capable of hovering in the air. It has a long, non-retractable proboscis, with which it can suck nectar directly on the fly, in the manner of hawk moths and hummingbirds. Such a proboscis, along with other features, creates a unique appearance, and once you see it, you are unlikely to confuse this fly with others.

Why do insects imitate wasps?
Predators with a long striped body and a stinger hunt for insects. Individuals attack prey that is much larger than them. The poison poisons the victim, and strong jaws help cope with resistance and crush tissue. Due to the aggressive behavior of wasps, even large animals and birds avoid them.
Mimicry as a predator protects against attack. The close external resemblance and coloring of the imitator deceives the aggressor. In butterflies and flies, the method protects against mobile vertebrates that use good vision. Bright, striped spots on the abdomen warn the hunter that the object is about to sting.
Mimicry of wasp predators increases safety. The poisonous specimen declares its inedibility. Each generation of animals learns through personal experience. If the aggressor has encountered the original source, he will not risk contacting the bug.
Wasps are dangerous predators that are avoided by animals, birds and insects. Successful imitation will protect the offspring and save lives. Imitators often live next to the object of mimicry and completely adopt the habits.
Hornet: description
In practice, a hornet is a large wasp, the length of which is in the range of 2-2.5 cm, while the queen is somewhat larger and can reach 3.5 cm in length. These insects can often be seen in gardens, summer cottages and in the wild outside the city. Their nests can be located anywhere, including under the roofs of outbuildings, in trees, in firewood and other places protected from weather conditions and easy access to them. A hornet can be easily distinguished from a wasp not only by its size, but also by the color of its chest: the wasp’s chest is black, while the hornet’s is brown with a reddish tint; in addition, the back of the hornet’s head is wider than the front.
The sting of a European hornet is much more painful compared to a bee or wasp. Due to the toxins contained in its venom, the human body tolerates a hornet bite more severely. In addition, the venom of this insect contains histamines, which can cause allergies. Despite this, single bites are not fatal. If we talk about the bite of a giant hornet, which lives in Southeast Asia, then untimely help can end very badly.
As a rule, only females that have a sting bite, but this does not make it any easier, since it is almost impossible to distinguish a female just like that.
Types of hornets and their lifestyle
Tireless builders construct cocoon-like nests from pieces of tree bark. Then the insects hang them in places protected from wind or rain: in attics, in the crown of trees, in a woodpile, etc. In such houses, the female lays eggs, and the remaining adults obtain food for the fast-growing offspring.
Since colonies of predators can be located in the most unexpected places, being outside the city, you need to be more careful. The hornets themselves are not aggressive and do not attack first. However, any sudden movement near the nest or its destruction signals danger and stimulates the production of an alarm pheromone, which determines the behavior of the entire swarm.
Asian hornet nest
Asian species are especially dangerous to humans, the bites of which are almost always fatal. The length of adult individuals reaches up to 5.5 cm, and the poison in the sting is highly toxic.
The bite of the European hornet, which lives on the territory of the Russian Federation, is more harmless and leads to the development of fatal complications only in the case of a rapid allergic reaction and the absence of timely anti-shock therapy.
How and with what does a hornet bite?
The method of destruction cannot be called a bite, because the insect does not bite, but stings. Powerful, developed jaws are designed for obtaining food: small midges, arthropods. The expression “the hornet strikes” is not without meaning, because when approaching the victim, the insect does not sit on the surface of the skin, but sticks its sting with lightning speed, literally on the fly, bending in a special way. After injecting the poison, the hornet removes its sting.
The sting, designed to protect against attacks from enemies, is located at the bottom of the abdomen, and only in females. It does not have serrations, like bees, which means it is suitable for repeated attacks. If a person does not threaten the peace of a swarm or an individual, he is safe.
But in case of sudden movements, attempts to kill an insect or catch it, it will not only sting the offender, but will also send a signal to the rest of the inhabitants of the nest. The fact is that during the insertion of the sting, pheromones begin to be released, signaling danger. Having received the signal, a whole flock of hornets, capable of biting to death, flies to the aid of their relative.

It is impossible to avoid a hornet attack, because the insect, which has an unusually fast reaction, stings from any position. If a person's face is hidden by a mosquito net, the hornet sprays poison, leaving severe burns on the skin and mucous membranes.
How to avoid insect bites?
Having an aggressive appearance, hornets are never the first to attack humans. There needs to be some reason for them to attack. Basically it is finding a nest near a person. Such a home is constantly guarded by several insects, which, in case of danger, make certain sounds. At this signal, other hornets flock and begin to attack the enemy.
To avoid being bitten, you must:
when going to the forest, you should behave very carefully and try to avoid places where these insects may live; you should not catch hornets; do not attack or kill an insect near its nest, because the signal it emits can cause a swarm of ferocious relatives to appear; Do not use food-grade fragrances or deodorants that cause alarms; if a nest is discovered, do not touch it, shake it or throw it to the ground; When insects appear, do not wave your arms or make sudden movements; take special care when collecting fruits and berries, which hornets love to feast on, gnawing into their pulp.
If a bite does occur, the consequences will depend on the number and location of the bites.

Types and description of hornets
There are over 20 varieties of these dipterans. Among them there are the most common and recognizable ones. Each has its own external characteristics. They also differ in habitat.
Ordinary
This is one of the largest representatives of the genus. The body length of males reaches 2.8 cm, that of queens – up to 3.5 cm. Their body structure is different. There is a modified apparatus for oviposition, which over time turned into a sting. It is also present in working individuals, but is absent in males.
On the abdomen there are alternating stripes of black and orange-golden, while the chest remains black. The female's cheeks and the back of the head are colored red, while the male's are orange. In all individuals, the anterior region of the head is yellow. The paws are brown-red.
The common hornet lives on the territory of European countries (with the exception of the southernmost and northern regions). It can be seen in Kazakhstan, southern Siberia, eastern China and Ukraine. This species is also found in the European part of Russia and North America.
Deplorable
This species of hornet is native to the Philippine Islands. Their body color is black or brown, depending on the subspecies.
Some insects have white stripes on their abdomen. A special feature of these dipterans is the ability to produce toxic poison. For this reason, it is better for a person to avoid meeting these insects.
Oriental
The hornet has a red-brown color and is relatively small in size. The uteri are quite large, reaching a length of three centimeters. Males and workers are somewhat smaller in size. This variety can be distinguished by the characteristic yellow stripe that runs along the abdomen.
They also have a wide yellow spot stretching from the mouthparts to the eyes. This species lives in the southern Russian regions, North America and on the island of Madagascar. Insects build their nests in the ground. This is due to the fact that their habitat is steppe and desert areas.
Dybovsky's Hornet
The uterus of this hornet reaches a length of 3 cm, males - 2.5 cm, working insects - 2.3 cm. They have light brown wings, brown-black chest and abdomen. This species is considered rare and is even listed in the Red Book. Such insects lead a parasitic lifestyle, attacking other hornets.
Giant Asian
This is the largest of all hornets found in nature. Its body reaches 6 cm in length, and its wingspan is 7.3 cm. For such unusual dimensions, the insect received the name giant. Its jaws are red-brown and its body is yellowish-copper. A distinctive feature is a large dark spot on the cephalothorax, as well as yellow and black stripes on the abdomen.
Japanese hornet
This is a type of the largest hornet that lives on the Japanese islands and is called the “sparrow-bee”. Diptera can only be found in the Land of the Rising Sun. Its wingspan reaches 6 cm. These hornets live in large colonies and prefer forest areas.
The number of individuals in a single hive can reach three hundred. Their diet mainly consists of small insects and flower nectar. At the same time, cases of attacks on people are often recorded. This happens at moments when a person is regarded by the hornet as a threat.
False Hornets
This can be used to describe insects that are mistakenly called hornets. In reality, they belong to other families and genera.
The most common misconceptions include insects that are called:
- Blue. This is a representative of bees - the purple carpenter bumblebee. The habitat is in the southern region of the country, including Crimea. For this reason, it is also called the Crimean hornet.
- Purple. He lives in the Caucasus.
- Red. In fact, this is the name of the uterus of the Oriental or Asian giant hornet.
- Zemlyanogo. This is the name given to all species that build colonies underground.
Hornets are interesting insects. They live according to a complex caste hierarchy. Due to the presence of poisonous glands, certain species become dangerous to animals and humans. Knowledge of the external features and habits of these dipterans allows you to become more familiar with their lifestyle and get rid of them in case of threat.
Butterflies in the form of wasps
A large insect that looks like a wasp may turn out to be quite an ordinary glass butterfly. However, this is not the only remarkable thing about the airy fluttering creatures. Most of them are distinguished by transparent wings. And if not for the contrasting border, it would be impossible to visually determine the presence of wings.
The most common species in the European part are poplar, currant, and apple. The insect is associated with the wasp exclusively by its bright yellow striped body color and flight style. Otherwise, it is a typical garden pest. The female lays eggs under bark scales near the buds. After a few days, caterpillars emerge from them, gnaw holes in the shoots and penetrate deep into the plant. They gnaw out the core, gradually descending to the base of the tree or bush. After wintering, they continue to eat the plant from the inside. And although an insect similar to a wasp does not bite a person, its harmfulness is significant. The offspring are located inside the trunks and branches, so the emerging pest can only be dealt with in a radical way - by pruning and destroying the affected areas.
An interesting picture is presented by the mating games of glass butterflies. The males gather in a circle near the female and begin to flutter around the lady, as if surprising her with their abilities and showing themselves in all their glory. The female can only choose the individual she likes.
Climaciella brunnea
The insect is very similar to a wasp, with a long body, and has huge limbs like a praying mantis. A representative of the mantispid family can be recognized by its thin, graceful body, colored brown with yellow horizontal stripes. Predators have well-developed enlarged front legs, which they use to grab prey. Males live only in the spring before mating.
Reproduction and lifespan
Mating of the wasp nest queen, which occurs in the autumn, occurs sometime in October. The male individuals of these insects are usually called drones, just like bees. The purpose of such a colony caste is to copulate with the queen.
They have no other responsibilities. In the fall, the queen has contact with several drones at once, and when she receives their sperm, she stores it in her body until the next spring. The males, having fulfilled their natural purpose, soon die. And the uterus falls into suspended animation for the entire period of severe cold and cold.
With the arrival of warmth, she, waking up from hibernation, immediately begins the work of building a nest. What material is used to construct the home of an aspen family has already been described; it should only be added that, like bees, it consists of cells.
First, the queen looks for a suitable place for the nest, and then builds honeycombs. And this entire structure ultimately ends up suspended on a branch or in a hollow tree or, as often happens, on the ceiling or attic of some building. A wasp nest can be found attached to window frames, in gardens and forests, and in abandoned burrows of small rodents.
As time passes, the next stage begins - the pupa. The larva turns into it, wrapping itself in a web. This is called a cocoon. After 3 days, the imago hatches from it, that is, the wasp in the adult stage.
Wasp mating
It should be noted that the eggs of these insects are not all the same. They may or may not be fertilized. The eggs of the first type produce a new queen and worker wasps. Here everything depends solely on the type of nutrition in the larval stage. Drones are given life by unfertilized eggs.
By mid-summer, the responsibilities of feeding the larvae are taken over by young wasp insects. They build honeycombs and feed the queen herself. By the end of summer, worker wasps stop hatching; in the autumn, only females and drones are born.
In some cases, the queen may lay her eggs in the fall. The resulting new generation of wasps goes in search of a pair to mate outside of their native nest. After completing the mission, the males, as usual, die. However, such a fate does not befall females. They hibernate in order to form their own new colony in the spring.
The process of a wasp emerging from a larva
The queen lives the longest in the aspen family. Its lifespan is about 10 months. Worker wasps, like drones, live much shorter lives - about four weeks.
After a warm winter (a secluded place is specially located for this), the queen begins to build a nest and lay eggs there. From these eggs only sterile individuals will emerge, which will further build the nest and obtain food.
And only towards the end of summer the queen begins to lay eggs, from which wasps will emerge capable of reproducing. It is these individuals that swarm and mate with each other.
One female mates once and is capable of producing more than 2000 wasps. For the most part, these are worker wasps, sterile. The eggs are sealed in a chamber along with small insects (food). The larvae will then feed and gain weight in order to turn into a wasp.
The larvae that will produce wasps capable of reproducing feed differently. They are fed food that promotes the formation of reproductive organs. After the wasp emerges from the larva, it climbs out of the chamber on its own. The queen is 10 months long, but worker wasps and drones are only 4 weeks old.
Family organization and behavioral characteristics
Hornets are social insects. They live in large colonies, building complex multi-tiered nests. The ancestor of the family, the queen, wakes up in the spring and begins to look for the most suitable place to build a nest.
Having found it, she also begins to form a future home for the family, in which she lays her eggs. After the larvae appear, he feeds them.
After the first generation of worker wasps grow up, all responsibilities for nest building, feeding, and feeding the larvae pass to them. The queen is only engaged in the reproduction of new hornets.
Hornets are highly developed insects. They distinguish each other and communicate using special signals. They lead a predominantly diurnal lifestyle, try to stay away from people, and do not show persistence like other wasps.
Safety regulations
Important to know! Neighborhood with the hornet family threatens many troubles. The stings of these representatives of the wasp family are very painful and dangerous to health. In people prone to allergies, a bite can cause anaphylactic shock, which leads to death
In people prone to allergies, a bite can cause anaphylactic shock, which leads to death.
- acute pain, swelling, inflammation, hematomas, in rare cases - suppuration;
- intoxication, dizziness, fever, nausea, migraine;
- allergic reaction;
- anaphylactic shock.
Insects themselves do not show aggression unless they see a threat to their home. Among other things, they are very useful in gardens and vegetable gardens: they destroy and eat pests. If it is urgently necessary to get rid of flying neighbors, do not neglect a protective suit or turn to professionals.
Hornets are arthropod insects that are large in size. Outwardly, they look like giant wasps. They move with the help of large wings, making a buzzing sound.
Hornets are characterized by:
- An adult hornet has an oblong body. Based on the species, the body can grow up to 5.5 cm.
- The head is large in size with antennae, the crown is wide. In color it is orange or black with slight splashes of yellow.
- Insects have two compound eyes and three ordinary eyes.
- In front of the head there are strong jaws, necessary for hunting, chewing food, and building nests.
- The belly is round in shape, in the area of \u200b\u200bcombination with the sternum it is tied with a thin waist. The color of the abdomen is represented by alternating transverse stripes of yellow and black colors.
- Females have a sting at the end of their belly, which is a modified ovipositor. It is located inside the belly and protrudes during a hornet attack.
- The surface of the sting is smooth, hollow inside. At the base of the sting there is a gland that secretes a toxic substance, and there is a reservoir where the poison accumulates. Compared to a bee's sting, a hornet has no barbs, so they, like other wasps, are capable of stinging their prey repeatedly.
- There are 3 pairs of legs extending from the hornet's chest. Each limb is represented by a complex structure.
- Hornets have two pairs of wings. The front wings are large, the hind wings are small. They are located on the front of the chest. When a hornet flies, its wings form a single plane, since the hind wings are attached to the front wings by small hooks.
Hornets are considered the leaders among insects that pose a threat to humans. This includes both poisoning and skin lesions. The insect is dangerous because the poison affects both the tissues of the stung area and the body as a whole.
As practice shows, even if a person deliberately catches a hornet, the insect will try to escape, but will not attack.
An attack by individuals occurs in the case of obvious aggression towards them. This happens when a person:
- destroys the nest;
- tries to grab with his hands;
- sits on an insect.
The following signs are identified after a hornet attack:
- The occurrence of throbbing pain in an acute form.
- The stung area swells, swelling occurs, a pathological process.
- The toxic substance leads to disorder of cells and vessel walls, which leads to the appearance of extensive hemorrhages. Dire situations are characterized by huge tumors, suppuration, and general intoxication of the body.
- The poison leads to headaches, increased heartbeat, dizziness, and increased temperature.
How dangerous is a wasp to humans?
They can cause material damage and also harm human health.
Materials include:
- spoilage of fruits: after bites, black spots appear that spoil the appearance of the fruit;
- apiaries: bees can serve as food, both protein food and nutritious nectar.
Human health:
Wasp venom is a colorless liquid with a bitter taste. Contains substances that cause pathophysiological reactions. Contains phospholipase, histamine, melitin - components that lead to allergic reactions, edema, tumors, cell destruction, and affect the human nervous system.
Children and the elderly are especially sensitive to wasp stings.
Wasps are aggressive in hot weather when there is a lot of food around. In this way, wasps protect their nest or themselves.
Wasp venom is much more dangerous than people think. In one species of individuals, the content of components in the venom is different. Individual intolerance by a person. It is unknown what the allergic reaction and its consequences will be.
List of subspecies
The Vespa species is represented by a large number of subspecies. At the moment, more than twenty species of these insects have been described. The most common of them are:
- Vespa analis is an Asian hornet that lives in Korea, Japan, and China;
- Vespa basalis – basal hornet, found in Laos, India, Nepal;
- Vespa biolor is a two-colored hornet found mainly in Hong Kong and Thailand;
- Vespa affinis is a small striped hornet that lives in Taiwan and Malaysia;
- Vespa bellicosa is a warlike hornet, most often found in Indonesia;
- Vespa crabro is a common hornet (hornet wasp), widely distributed in Europe.
Also in small areas there are Bingham, tropical, ardent, variable, lamentable, multi-spotted, yellow and other species of this insect.

Dream Interpretation - Bite
A dream in which you bit your man means true love; if he did the same, there is complete reciprocity between you, based on common spiritual interests. If you are bitten by a rabid animal, this means illness and failure; if it is a lion, you will experience pressure from competitors. A dream in which you received a fatal bite from a poisonous snake and are shuddering in death convulsions is a sign of impatience in anticipation of upcoming intimacy with a man. If you are bitten by a small but feisty dog in a dream, in reality you will suffer minor losses, and if a huge dog bites you, your financial situation will sound an alarm. Being bitten by fleas, bedbugs or ticks will leave an unpleasant aftertaste on your soul from meeting a vile type who once dishonored you.
Life cycle features
To learn more about an insect, consider its life cycle from birth to death.
Birth
A single queen gives life to an entire generation of a family of giant wasps. In the spring she finds a place to build a house for a new colony. The female makes the first honeycombs herself, then lays eggs in them. After a few days, larvae appear and require animal food. Their mother regularly goes hunting for caterpillars, beetles, butterflies and other insects. The grown larvae wrap themselves in silk thread and turn into pupae. Two weeks later, the young hornets gnaw the path of their cocoon.
Maturity
In July, several working males and females grow up and are ready to take care of the family. They help complete the construction of honeycombs and fly for protein for the larvae. The queen stops leaving the house and concentrates on laying eggs. How long do hornets live? The life of working females and males is very short. They grow up at the end of summer, and in September most of the individuals die. The rest survive until the first cold weather.
In early autumn, the family reaches its population peak. In the last clutch, the queen laid fertilized eggs, from which females emerged that could become new queens. Individuals born earlier had altered ovaries; their functioning was suppressed by the queen’s pheromones. Young females and males begin to swarm around the nest and mate. The insects will save the sperm obtained in the fall to found a new family. After mating, males will live for about a week. The old queen loses her ability to reproduce and is driven out onto the street or killed.
Where do they winter?
Only fertilized queens overwinter. Males and workers die with the onset of cold weather. The uterus begins to actively feed at the end of summer - at the beginning of autumn, accumulating nutrients.
Then find the most suitable place for wintering. It should be secluded, safe, protected from the wind.
Insects climb into abandoned hollows, under the bark of trees, into the cracks of wooden buildings and even into piles of fallen leaves and fall asleep. The uterus wakes up in the spring, when the average temperature reaches + 10⁰С.
Emergency care for a hornet sting
- You need to take an antihistamine, this will stop the allergic reaction.
- It is not worth sucking out the poison, because the skin at the site of the bite has tightened.
- You need to apply cold to the bite site to reduce swelling.
- If the temperature rises above 38 degrees, you need to take an antipyretic, except for children under 12 years of age.
- Drinking alcohol is prohibited.
- It is necessary to monitor the condition of the bitten person for a day and if the state of health worsens, go to an ambulance.
In general, large individual wasps are quite peaceful. However, despite the fact that insects are beneficial by exterminating some pests of gardens and household plots, they are rather dangerous neighbors.
Why is a tree bumblebee bite dangerous?
The bumblebee, due to its biological characteristics, does not bite, but stings, introducing a toxic composition under the human skin. Only the female of the species, which is not aggressive in nature, is capable of stinging. When confronting a person, the possibility of avoiding a bite is high. It is rare to see a female building a nest, but the bee will defend itself and the created tunnel with its offspring if something threatens it.
Important! To avoid unnecessary contact, the insect should not be irritated or approached close to it. The carpenter bee is twice as large as the usual honey bee, so its bite is noticeably more painful.
The bite of a carpenter bumblebee is dangerous due to the poison in its sting and severe swelling of the bite site. If a skin puncture can only result in painful sensations that subside after a while, then a sting in the eye, nose or throat is life-threatening. A bite to the neck can cause suffocation due to swelling or allergic reactions.
Important! If you need to remove an insect nest, you should definitely use protective clothing, especially on exposed areas of the body.
Insects of the xylocope species are especially active in spring.
Black bumblebees do not like noise, so you can drive them out by making loud noises near the nest.
The place where the bumblebee carpenter worked will be revealed by a perfectly even hole in the wood, as if drilled with a construction tool, and piles of shavings nearby.
What does a hornet look like?
Winged predators have a size that varies depending on the species. Common insects do not exceed 3.5 cm in length. Vespa mandarinia is considered the largest, the length of which can vary from 4 to 6 cm.
They have some differences that make them stand out from other hornets, namely: an enlarged head, a wide crown, and the back of the head, which is located behind the facet-type eyes. These hornets also have 3 regular eyes. The color of the head can vary from yellow to brown. The antennae are a distinct brown color, the number of branches of which varies in both sexes. The jaws are called mandibles. They can match the color of the head.
Representatives of these insects have a round abdomen. The waist is located at the junction of the chest and abdomen.
Unlike the wasp, which has clearly defined alternating yellow-black stripes, in hornets they are not very clearly depicted on the body.
Some species have a naturally brown or black abdomen, with a red, yellow, or white stripe sometimes visible. The entire body is covered with not very thick hairs of varying lengths.
The hornet has 2 pairs of wings. They are big in front, smaller in back. When at rest, the front wings fold and lie on the back. If the insect is about to fly, the hind wings “stick” to the front wings and form a single wing.
The legs of hornets can also differ in color: they are characterized by black, yellow, and brown shades. There are 3 pairs of them. The legs consist of several parts: at the top is the coxa, then is the trochanter, in the middle is the thigh, below is the tibia with a spur, and at the end is the tarsus.
All females have an ovipositor at the very end of the abdomen (only in the uterus it performs the function of procreation), which is the sting. In a state of calm it is drawn inward. The poison is located at the very base of the sting, which, like that of a wasp, is smooth. This explains the fact that the hornet stings several times at once, since it can calmly pull the sting out of the victim’s body.
Carpenter bee: how to get rid of it
To detect unpleasant neighbors, it is enough to know a few facts about them:
- The carpenter bee prefers weathered wood from softwood trees;
- A painted or treated surface will not attract insects - they need natural raw materials to build a nest;
- The greatest activity is observed in the spring - it is during this period that young individuals look for a place to live.
If you detect carpenter bee passages, use one of the following:
- Insecticides, gasoline or just water;
- Sealants, glue, steel filings for puttying passages;
- Essential oils of citrus and almond.
When carrying out work, do not forget about personal protective equipment, and if there are a lot of nests, then resort to the services of professionals.
Although violet xylocopa poses a danger if contact is too close, its positive qualities (hard work, unpretentiousness, non-aggression) attract beekeepers who continue to try to domesticate the carpenter bee. However, to date, all of them remain unsuccessful - representatives of the species prefer natural conditions of the wild.
Reproduction
The hornet is an insect with a strict hierarchy in the swarm, which allows for good organization of reproduction, feeding, construction of nests, rearing of larvae, and protection of the colony from enemies. With the arrival of warmth, the queen flies around the territory and looks for a place for a nest. Having chosen a place, he establishes cells of the cells. One egg is placed in each cell; after 5-8 days, a larva measuring 1-2 mm in size is born. In a couple of weeks the larva turns into a pupa, after 13-15 days it becomes an adult wasp, gnaws through the cell and climbs out.
When adult adults appear, the queen gives them the construction of honeycombs and care of the offspring and no longer flies out of the nest. Working wasps obtain food for larvae, water, and materials for construction. Hornets do not sleep, they work at night too. In the fall, the queen lays eggs with females for procreation. Young females mate with males, after which they die. In the fall, the old queen of the hive and unfertilized females die. Fertilized queens overwinter in the hive and establish their own nest the following season.
Carpenter bee: features of vital activity
Despite the name “solitary bees,” representatives of the species still have contacts, since the instinct of procreation is one of the main ones in nature. Each male protects his territory, where 5-6 females live. When a new individual appears, the male rises to a height (branch or bush) and attracts her attention with a strong buzz. If the female does not leave the nest, the male can penetrate inside and appear outside up to several times until his chosen one pays attention to him.
Although not an active honey plant due to the absence of a queen, the carpenter bee is nevertheless distinguished by great endurance and is able to fly long distances in search of food. Representatives of the species are hard-working and work even in bad weather, making the carpenter bee a valuable pollinator.
Important! In the same nest, up to 10 generations of xylocope can change - the dwelling will remain inhabited until the wood deteriorates. Although insects prefer secluded habitats (forest edges, steppes, forest-steppes), often the lack of suitable material pushes them to colonize human homes. In this case, there may be a threat to life, since a sting in the throat of such a bee is fatal.
What types exist
Now let's talk about what types of hornets exist, and what are the characteristics of each of them.
Overall, there are more than 20 representatives of this genus of Hymenoptera. But we will consider only the most common of them.
So, let's highlight the following types of hornets:
- Common or European hornet. The common hornet (Vespa crabro) is the most common species, living in the central and southern parts of Europe, Russia, Ukraine, as well as China, Mongolia, South Korea, Japan and the USA. We can say that this is the same yellow hornet that a resident of the countries of the former USSR may encounter. It has all the classic external characteristics for its taxon. The length usually ranges from 2 to 3.5 cm. The head and chest are brown, the abdomen is yellow with black transverse stripes. Large mandibles and large eyes, as well as sexual dimorphism in favor of females, indicate that this wasp belongs to the genus of hornets.
- Eastern Hornet. The most pretentious representative of its kind in appearance. It has a color that distinguishes it from other species with one wide transverse yellow stripe on the abdomen. The body and wings themselves are bright purple. Dimensions range from 2.5-3 cm. This is the most heat-resistant representative of the genus, capable of living in steppes and deserts. The homeland of this most beautiful species is North Africa, about. Madagascar, as well as hot regions of Asia and Europe.
- Dybovsky's Hornet. It has a second name - Black Hornet. Interesting in appearance, having an almost solid black body color and brownish wings. Only on the abdomen can you see several thin dark orange stripes. A very rare species, found exclusively in regions of Asia, including countries such as Thailand, India, Japan, China and Korea, and the Russian Transbaikalia. The body length does not exceed 3.5 cm, like most other varieties.
- Asian giant hornet. He is also the hornet Vespa mandarinia. This is not only the largest hornet in the world, but also the largest representative of the wasp family in general. The huge Asian hornet can reach a length of 5.5 cm. Its wingspan can cover a human palm and is 8 cm. It is indeed a very large wasp, reminiscent of a small bird in flight, which gave it the local name among the Japanese “sparrow bee”. Such a huge hornet poses a high threat to humans and domestic animals, since the danger of these insects is directly proportional to their size.
And these are not all types of hornets, there are also the Philippine Vespa luctuosa, the tropical Vespa tropica, the Asian Vespa velutina, and many other interesting varieties.
bumblebee carpenter
The carpenter bumblebee is distinguished by its ability to build tunnels inside wood, in which it breeds offspring and overwinters.
Insects choose trees for their nests that are old, dry, loose, with peeling bark; rotten stumps are also suitable. A tree or other place where a nest is formed, if its condition is suitable, bees can use for up to 14 years in a row, settling in them from year to year. Having chosen ready-made, but old, holes once left by other representatives for laying eggs, bees are able to repair them, holding the wood together with their saliva. The main condition for choosing a place for a nest is dryness and softness of the material. Insects will never choose a fresh, healthy tree. If possible, several bees make holes in the same material next to each other.
In the wood, with the help of powerful jaws, insects gnaw out a hole - an even circle, with a diameter the size of a purple bee. The passage is made from the south side of the tree and first has a horizontal direction, and then goes down and inside the tree at a distance of about 30 cm. Such a tunnel is needed for laying larvae, which will be in it one above the other and will independently go through all stages of development to a fully formed adult individual .
Fighting hornets in the house
Considering the danger of bites, the proximity of a hornet nest to people is undesirable. If there are uninvited neighbors under the roof of a house, in a barn or on a tree nearby, you need to get them out. It is useless to fight individual individuals - in order to destroy the queen and the entire colony, it is necessary to destroy the nest. This will help you do this:
- Chemicals. The plastic bag is treated from the inside with insecticides and placed on the nest. The top edges of the bag are glued with tape to the surface on which the nest is located, so that the hornets do not fly out. Effective means: Dichlorvos;
- Get;
- Raptor;
- Karbofos;
- Tetrix.
Sometimes, to combat hornets, traps made of plastic bottles with sweet liquid are used as bait. The insects fly into the bottle and can’t get out. But this method makes sense only with a small number of insects flying in from somewhere. The nest cannot be destroyed this way.
A hornet trap is a very simple but ineffective remedy.
You can also try traditional methods, they are less effective, but they are accessible and mostly safe for people and pets:
- red pepper pods are hung next to the nest;
- poison insects with boric acid, adding meat or sweets as bait, and placing poison near the nest;
- the hornets' home is doused with boiling water;
- all exits from the nest are filled with foam - the hornets will die inside from lack of water and food;
- you can also fill the nest with foam from a fire extinguisher;
- make a water trap by placing a bucket of water so that the entire nest is flooded;
- It is believed that planted mint, geranium, and lemon balm repel hornets.
