How to recognize which insect has bitten you

 - Чей это укус?

Stings and insect bites are painful conditions associated with insect bites (mainly hymenoptera and diptera).

Few in life manage to avoid insect bites. In summer, this problem is especially relevant.

Sometimes it's hard to determine who bit you. The wound can hurt, itch, swelling may appear. But no need to panic. We created a cheat sheet so you know exactly which insect has attacked and bit you.

Mosquito

Комар - Чей это укус?

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

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

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

Комар - Чей это укус?

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

Mobile larvae and pupae of mosquitoes live in stagnant bodies of water. Fossil mosquitoes have been known since the Cretaceous. In the modern world, there are more than 3,000 species of mosquitoes belonging to 38 genera. In Russia, representatives of 100 species belonging to the genera of real mosquitoes (Culex), bites (Aedes), Culiseta, malaria mosquitoes (Anopheles), Toxorhinchites, Uranotaenia, Orthopodomyia, Coquillettidia live.

Mosquito-squeak, or common mosquito (Latin Culex pipiens) - a polytypic species (otherwise - a complex) of blood-sucking mosquitoes (Culicidae). Distributed around the world and has great epidemic significance. Most mosquitoes occur in sizes of 3 to 7 mm. Females feed on plant juices (to maintain life) and blood (to develop eggs), mainly humans, and the male feeds exclusively on plant juices. .

Female mosquitoes are carriers of various human diseases, for example, Japanese encephalitis, meningitis, as well as animals, such as bird malaria. The forms of the nominative subspecies of the Piskun mosquito Culex pipiens pipiens forma pipiens and Culex pipiens pipiens forma molestus are the main objects of research in the form

Mite

Клещ - Чей это укус?

The body reacts to a tick attack with a red spot at the site of the bite.

The insect can be on the victim for a long time and increase in size, feeding on its blood.

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

If after removing the insect the round spot on the skin has not passed, but only increased in size, consult a doctor soon.

Клещ - Чей это укус?

Ticks (lat.Acari) - a subclass of arthropods from the class of arachnids (Arachnida). The largest group in the class: currently more than 54 thousand species, including 144 minerals, are described. Ticks reached such heyday due to the fact that in their historical development they acquired microscopically small sizes, which allowed them to master the upper layers of the soil, rich in decaying plant debris.

Fleas

Блохи - Чей это укус?

Flea bites can be confused with allergies or mosquito tricks, because similar red swelling appears on the skin.

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

Fleas usually attack 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.

Блохи - Чей это укус?

Human flea (lat. Pulex irritans) is a flea species from the Pulicidae family. It is found everywhere.

A dangerous parasite of humans, dogs, and sometimes other animals, which is a carrier of the plague pathogen, and can also be an intermediate host of some helminths.

Bee

Пчела - Чей это укус?

In the place of a bee sting, its sting may remain, which must be carefully removed.

The skin usually turns red, a swelling appears. A person feels acute pain and burning, and after some time a severe itch.

If there is no allergy, then the troubles that have to be experienced end there.

If there is an allergy to bee venom, then a person may begin to suffocate, and here you can not do without medical assistance.

Пчела - Чей это укус?

Bees (lat. Anthophila) - section in the superfamily Apoidea of ​​flying insects of the suborder Cepalaceous winged hymenopteran order, related to wasps and ants. The science of bees is called apiology (apidology).

Honey bee (Latin Ápis melliféra) is a species of public bees of the Apidae family of the Apinae subfamily.

Wasp

Оса - Чей это укус?

Symptoms after a wasp attack are similar to those that occur after a bee attack.

A red swelling, sharp pain and burning, and then an intolerable itching appear at the site of the bite. There may be hemorrhages on the skin.

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

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

A person will feel a burning pain, even more acute than with a wasp sting. Since 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, you need to urgently consult a doctor.

Оса - Чей это укус?

Wasps - the name of some insects from the suborder Cepuliformes (Apocrita) of the hymenoptera order, which does not have a strictly scientific definition.

In principle, these are all stinging bellies, not related to bees and ants.

Hornet

Шершень - Чей это укус?

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

A person will feel a burning pain, even more acute than with a wasp sting.

Since 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, you need to urgently consult a doctor.

Шершень - Чей это укус?

Hornets (lat. Vespa, lit. "wasp") - the genus of the largest representatives of the so-called public wasps.

The largest representatives of the genus (Vespa mandarinia) are up to 55 mm in length.

Ant

Муравей - Чей это укус?

Most ants are not dangerous to humans.

But, for example, fiery red can cause trouble.

On the places of his bites pustules are formed - pustules, which then turn into scars.

Ant poison contains toxins, and a person may experience severe allergies or anaphylactic shock.

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

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

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

Муравей - Чей это укус?

Ants (lat. Formicidae) - a family of insects from the superfamily of the ant order Hymenoptera. They are social insects, forming 3 castes: females, males and working individuals. Females and males are winged; working individuals are wingless. Antennae are articulate, 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 rear part of the chest (epinotum) is the first segment of the abdomen, merged with the posterior chest. Actually, the abdomen joins the epinotum with a stalk formed by the first or second segments. The ants of some subfamilies (myrmycins, ponerins, and others) have a developed sting. Reduced venation wings.

Horsefly

Слепень - Чей это укус?

Horsefly is like a big, fleshy fly.

But, unlike her, it can be quite painful to bite a person and eat on his blood.

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

Then there is swelling and itching.

Horseflies carry various diseases such as tularemia and anthrax, but more often attack livestock than people.

Слепень - Чей это укус?

Gadflies (Latin Tabanidae) - a family of dipterans from the suborder Short-billed. Adult females of many representatives are a component of the midge. Numerous in the forest zone, steppes and deserts, but usually stay on the banks of rivers and lakes, where many species of larvae develop. The world fauna describes about 4400 species that unite in about 200 genera; in the CIS countries about 200 species. Fossil horseflies have been known since the Oligocene.

Louse

Вошь - Чей это укус?

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

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

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

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

Вошь - Чей это укус?

Lice (lat.Anoplura) - a suborder of small obligate ectoparasites, a detachment of lice (Phthiraptera). The mouth organs of lice are adapted to pierce the skin of an animal host and absorb blood. Lice are highly specialized parasites; they live only on one or on some related animal species. This feature of lice in some cases makes it possible to find out the affinity of the host species. Lice, for example, human louse (Pediculus humanus), are carriers of dangerous diseases such as rash and relapsing fever. Distributed around the world.

Bug

Клоп - Чей это укус?

At first glance, bedbug bites look like traces from an attack of fleas, mosquitoes or allergies.

Swelling, redness, and severe itching are felt on the skin.

But you can distinguish the "work" of bedbugs by the characteristic chains-paths on the skin.

Bites are close to each other.

And bedbugs bite harder than mosquitoes.

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

Клоп - Чей это укус?

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

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

Клоп - Чей это укус?

Bedbug (lat.Cimex lectularius) - a species of bedbugs, a common obligate synanthropic blood-sucking insect.

It is an ectoparasite of humans and warm-blooded animals - it feeds on their blood.

Etiology

The stinging produced by some insects from the Hymenoptera order with the help of a sting produces a poisonous liquid formed in special glands into the wound (see Hymenopterism).

Mosquito bites cause itching (see Culicidosis), as well as flea bites (see Dermatophiliasis).

Parasitization of lice leads to itching, dermatitis and other pathological skin manifestations (see Pediculosis, Fthyriasis).

The reaction to bedbugs can occur from pruritus to anaphylaxis (see Chemipterosis). Also the person is bitten by mosquitoes (see Phlebotoderma), horseflies (see Tabanidosis), midges (see Simulidotoxicosis) and other dipterans. The person can be bitten also by thrips (see. Tizanopterny dermatitis).

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

In addition to insects, centipedes can bite from arthropods of a person (see millipede bites), spiders (see Arachnidism, Latrodectism, Loxoselism), scorpions (see Scorpionism), saltpugs, poisonous ticks (see Tick-borne paralysis) (see also Arthropod bites) )

The clinical picture and symptoms

There are three types of reaction to a bite. A common reaction involves the area around the bite with redness, itching, and pain. Large local reactions occur when the tumor area is more than 5 cm. Systemic reactions occur when symptoms of the lesion are observed in areas of the body that are far from the bite.

A 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.

Clinical manifestations of stinging insect bites range from minimal pain and local erythema to life-threatening anaphylactic reactions. Local reactions can vary from a papule or blister at the site of the bite to edema of the entire limb. Clinical signs of anaphylactic reactions associated with sensitization to stinging insects are similar to manifestations 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 proceed differently: from local symptoms to shock with a fatal outcome. There are 4 types of general reactions:

    1) Mild general reactions: urticaria, itching, malaise, fear. 2) General reactions: shortness of breath, abdominal pain, nausea, dizziness, vomiting join the symptoms of the 1st type. 3) A severe form of general reactions: in addition to the previous manifestations, suffocation, dysphagia, hoarseness, incoherence of thoughts, fear join in. 4) Shock: in addition to the above symptoms, cyanosis, a drop in 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, numbness, coma.

The simultaneous stinging and biting of a large number of insects, such as bees, can be fatal.

In severe cases, death occurs mainly due to asphyxiation followed by vascular collapse.
