How to recognize exactly which insect has bitten you

 - Чей это укус?

Sting and insect bites are painful conditions associated with insect bites (mainly Hymenoptera and Diptera).

Few people in life can avoid insect bites. In the summer, this problem is particularly relevant.

It is sometimes difficult to determine who bit you. The wound may ache, itch, swelling may occur. But do not panic. We created a cheat sheet so that you know exactly which insect attacked and bit you.

Mosquito bites look like puffy redness the size of a small berry.

Most often they are located on open areas of the body.

Mosquitoes bite where the skin is thinnest and easier to reach the blood vessels. Biting, they inject saliva into the wound together with anticoagulants that thin the blood. They cause tissue swelling, redness and itching.

Mosquitoes, or real mosquitoes, or blood-sucking mosquitoes (lat. Culicidae) are a family of Diptera insects belonging to the group of the long-caped (Nematocera), the females of which are in most cases a component of the gnus complex. Oral organs are characteristic of this family: the upper and lower lips are elongated and form a sheath in which long, thin needles are placed (2 pairs of jaws); males have underdeveloped jaws - they do not bite.

Motile larvae and pupae of mosquitoes live in stagnant bodies of water. Fossil mosquitoes are known from the Cretaceous period. In the modern world there are more than 3,000 species of mosquitoes belonging to 38 genera. Representatives of 100 species belonging to the genera of real mosquitoes (Culex), Kusak (Aedes), Culiseta, anopheles mosquitoes (Anopheles), Toxorhinchites, Uranotaenia, Orthopodomyia, Coquillettidia live in Russia.

Mosquito-piskun, or common mosquito (lat. Culex pipiens) - a polytypic species (otherwise - a complex) of blood-sucking mosquitoes (Culicidae). It is widespread all over the world and has a great epidemic significance. Most occurring mosquitoes range in size from 3 to 7 mm. Females feed on plant sap (for life support) and blood (for egg development), mainly on humans, and the male feeds exclusively on plant sap. .

Female mosquitoes are carriers of various human diseases, such as Japanese encephalitis, meningitis, as well as animals, such as avian malaria. Forms of the nominative subspecies of the culex pipiens pipiens forma pipiens and culex pipiens forma molestus mosquito-piskiens are the main objects for research in the form

On the attack of the tick, the body reacts with a red spot at the bite site.

An insect can stay on the victim for a long time and grow in size, feeding on its blood.

The worst thing is that ticks infect humans with encephalitis, borreliosis and many other diseases.

If after the removal of the insect a round spot on the skin did not pass, but only increased in size, rather consult a doctor.

Mites (Latin Acari) - a subclass of arthropods from the arachnid class (Arachnida). The most numerous group in the class: more than 54,000 species are currently described, including 144 minerals. Ticks reached such a flourishing due to the fact that in their historical development they acquired microscopically small dimensions, which allowed them to master the upper layers of the soil, rich in decomposing plant residues.


Блохи - Чей это укус?

Flea bites can be confused with allergies or tricks of mosquitoes, because on the skin appear similar red swelling.

But, unlike mosquitoes, these insects bite quite painfully, the bites from them itch much more.

Fleas usually attack the legs and only a sleeping person can bite in other places.

One insect can bite a person several times, so often the distance between the spots is 1–2 cm.

Fleas carry many dangerous diseases for humans.

At the site of the bite appear red swelling, acute pain and burning, and then unbearable itching. There may be hemorrhages on the skin.

A wasp can bite a person several times. As in the case of a bee, it is important that there is no allergy to insect venom, otherwise anaphylactic shock may occur.

At the site of the hornet bite, redness and swelling of tissues occur, blisters may appear.

A person will feel a burning pain, even more acute than with a wasp sting. Since the hornets are larger than their relatives, their poison is more toxic. It has histamine and acetylcholine.

If after a hornet bite a person feels cold in the limbs, his ears and lips turn blue, it becomes difficult to breathe, an urgent need to see a doctor.

Most ants do not pose a danger to humans.

But, for example, red fire can cause trouble.

On the ground of his bites pustules form - pustules, which then turn into scars.

The bite of a more harmless red forest ant looks like a mosquito bite.

A pink stain appears on the skin, which will then itch.

At the moment of a bite, the person will feel a burning sensation, as if boiling water has hit the skin.

Ants (lat. Formicidae) - a family of insects from the superfamily of the ant order of Hymenoptera. They are social insects forming 3 castes: females, males and working individuals. Females and males are winged, working individuals are wingless. Antennae articulated, in females and working individuals 11–12-segmented, in males 12–13-segmented, in a number of species 4-, 6- or 10-segmented. The main segment of the antennae (scape) is usually much longer than all the others. The posterior part of the chest (epinotum) is the first abdominal segment, merged with the posterior loom. The abdomen proper joins the epinotum with a stalk formed by the first or second segments. Ants of some subfamilies (myrrhizins, ponerins, and others) have a developed sting. Wings with reduced venation.

Gadfly looks like a big fleshy fly.

But, unlike her, it can be painful enough to bite a person and be supported by his blood.

First, a small red spot of more than 1 mm in diameter can be seen at the site of the bite.

Then there is swelling and itching.

Blind people carry various diseases like tularemia and anthrax, but more often attack livestock than people.

Blind (lat. Tabanidae) is a family of dipterans from the suborder short-lived. Adult females of many representatives are the component of the nasal. Numerous in the forest zone, steppes and deserts, but usually keep along the banks of rivers and lakes, where larvae of many species develop. In the world fauna about 4400 species are described, which unite in approximately 200 genera; in the territory of the CIS countries about 200 species. Fossil gadflies have been known since the Oligocene.


Вошь - Чей это укус?

If you notice small red dots, similar to mosquito bites, in places where hair grows thick, on the head, neck or behind the ears - you are bitten by head or pubic lice.

If there are such points on the back, abdomen, arms and legs - these are tricks of linen lice.

Bites are located at a distance of several centimeters from each other, and on the site of the bite you can see a trace of skin puncture.

Lice are carriers of dangerous diseases, such as trench fever and typhoid.

Вошь - Чей это укус?

Lice (lat. Anoplura) - a suborder of the small obligate ectoparasites, detachment of the feather-eared (Phthiraptera). Oral organs of lice are adapted to pierce the skin of the host animal and to absorb blood. Lice are highly specialized parasites, they live only on one or on some related species of animals. This feature of lice in some cases makes it possible to find out the closeness of host species. Lice, such as the human louse (Pediculus humanus), are carriers of such dangerous diseases as typhus and relapsing fever. Distributed throughout the world.

At first glance, bedbug bites look like signs of a flea, mosquito or allergy attack.

On the skin you can notice swelling, redness, there is a strong itch.

But to distinguish the "work" bugs can be on the characteristic chain-tracks on the skin.

Bites are close to each other.

And bedbugs bite more than mosquitoes.

Multiple paths on the body can be found in the morning - bugs go hunting at night.

Клоп - Чей это укус?

Bedbugs (lat. Heteroptera) - a suborder of insects from the order Hemiptera (Hemiptera), previously considered as an independent unit.

About 40 thousand species from more than 50 families. In the Far East of Russia there are about 800 species (for the former USSR, more than 2000 species have been indicated).

Клоп - Чей это укус?

Bed bug (lat. Cimex lectularius) is a species of bugs, a common obligate synanthropic blood-sucking insect.

Is an ectoparasite of man and warm-blooded animals - feeds on their blood.


The sting made by some insects from the hymenoptera detachment (Hymenoptera) with the help of a sting, releases into the wound a poisonous liquid that forms in specific glands (see Hymenopterism).

Mosquito bites cause itching (see Kulitsidoz), as well as flea bites (see Dermatophiliases).

Lice parasitism leads to itching, dermatitis and other pathological skin manifestations (see Pediculosis, Phyriasis).

The reaction to bedbug bites can manifest itself from itching to anaphylaxis (see Hemipterosis). Humans are also bitten by mosquitoes (see Phlebotodermia), gadflies (see Tabanidosis), midges (see Simulidotoksikoz) and other diptera. A person can bite and thrips (see Tizanopteric dermatitis).

Bites of blood-sucking insects (and ticks) can lead to infection with vector-borne diseases, such as malaria, leishmaniasis.

In addition to insects, arthropods can bite human centipedes (see centipede bites), spiders (see Arachnidism, Latrodectism, Loxosselism), scorpions (see Scorpionism), solpugi, poisonous mites (see Tick-borne paralysis) (see also Arthropod bites). ).

Clinical picture and symptoms

The reaction to the bite is of three types. The usual reaction involves the area around the bite with redness, itching and pain. Large local reactions occur when the area of ​​the tumor is more than 5 cm. Systemic reactions occur when symptoms of damage are observed in areas of the body that are far from being bitten.

The skin reaction to insect bites usually lasts from several hours to several days. However, in some cases, a local reaction can last up to two years. These bites are sometimes mistakenly diagnosed as types of benign or cancerous lesions.

The clinical manifestations of stinging insect bites range from minimal pain and local erythema to life-threatening anaphylactic reactions. Local reactions can vary from papules or blisters in the area of ​​the bite to swelling of the entire limb. The clinical signs of anaphylactic reactions associated with sensitization to stinging insects are similar to those of anaphylaxis caused by other causes. The patient may experience generalized urticaria, obstruction of the upper and to a lesser extent lower respiratory tract, and circulatory collapse.

Allergic and toxic reaction

Allergic reactions are different: from local symptoms to shock with a fatal outcome. There are 4 types of common reactions:

    1) Easy general reactions: urticaria, itching, malaise, fear. 2) General reactions: dyspnea, abdominal pain, nausea, dizziness, vomiting are associated with type 1 symptoms. 3) Severe form of general reactions: in addition to previous manifestations, suffocation, dysphagia, hoarseness, incoherence of thoughts, fear join. 4) Shock: in addition to the above symptoms, cyanosis, falling blood pressure, collapse, involuntary defecation, loss of consciousness.

Toxic reactions develop with the simultaneous bite of a large number of insects. Symptoms appear after a few hours in the form of edema, headache, vomiting, diarrhea, fever, cramps, stupor, coma.

Simultaneous sting and bites of a large number of insects, such as bees, can be fatal.

Death in severe cases occurs mainly due to asphyxiation, followed by vascular collapse.
