Elk fly in the apartment. Elk Mite

Parasite with the name "moose louse" in nature does not exist - this is based on the data of scientists. But people call it a special kind of bloodsucking flies that look like lice in appearance and way of life. The scientific name of this insect is deer blood-sucking.

Deer bloodsucking is an insect from the order of Diptera, family - bloodsuckers. It is also called elk fly, tick and louse.

The size of deer bloodsucking is 3-5 mm, females are larger than males. After the fly is drunk with blood, it can increase in size due to the elastic abdomen. Also, the abdomen greatly increases in females during the gestation of the pupa.

At the bloodsucker, the oral apparatus is a piercing-sucking type and six powerful legs equipped with claws, to hook onto the skin or hair of the victim.

The habitual habitat of elk lice is the European part of the Russian Federation, the Scandinavian countries, China and Siberia. The deer bloodsucker was accidentally brought to North America, where it successfully took root.

Features of life

Fly has strong wings up to 5 mm long, but flies badly enough, and in rainy or windy weather will never dare to fly. In fact, she only needs wings for one flight, from tree or land to the body of the chosen victim. After the deer bloodsucker found the carrier, within a few hours the process of dumping the wings and atrophying the muscles responsible for the flight begins. After dropping the wings, the insect lives on the body of the bearer until death, without leaving it, than and like the lice. Wingless deer bloodsucking looks very much like a louse.

On the head of the insect there are two large faceted eyes and three additional eyes. But it does not help the fly to see well. Choosing a victim, she is guided by the size of the animal and the heat coming from his body. If there is no larger target nearby than the person, the deer bloodsucker will try to settle on it.

If the company has adults and children, the elk louse ignores children, attacking only adults as more attractive objects. Although the blood of people does not quite fit these insects: feeding on it, they can not give offspring.

Deer blood-sucking is a viviparous insect. They do not lay eggs, but nurture their larvae in the abdomen, feeding them through special glands. When the larva turns into a puparium (a hard pupa), the female will give birth to it and it will fall to the ground, where it will remain until the next summer until a young fly hatches from it. One female pupil needs 2-3 days to form a single puparium, young individuals reach sexual maturity after 16-19 days from the moment of the initiation of blood supply.
If you have found one sexually mature moose louse, most likely, next will be the second. These insects form permanent pairs: male and female are constantly in close proximity to each other.

Danger to humans

As already mentioned, a person for deer bloodsucking is not a desirable carrier, and the victim, who was attacked by mistake.

Everyone is carrying the moose-louse attack in his own way: some people completely do not notice bites, and others call them very painful. Bites also manifest themselves in different ways: these can be red spots or swollen nodules, and nodules appear after a couple of days. There may be severe itching.

Let's call it three reasons why people should beware of these insects:

Each mushroom picker, going to the forest, understands that there he is waited not only by mushrooms or berries, but also by blood-sucking insects. If a person can be protected from mosquitoes with special sprays and gels, it is unlikely to be saved from a deer bloodsucker.

Who are moose fleas?

These have many names, but elk, or deer, they are called because these animals became the main breadwinners of fleas. However, fleas can often attack smaller forest dwellers, such as foxes, badgers, wild boars. They were found in the wool of bears and even on birds. Naturally, having entered the forest, a person can also be attacked by such an insect as a deer bloodsucker, whose bite is quite unpleasant.

The habitat of the insect is extensive: it occurs in North America and Scandinavia, in the European part of Russia, in Siberia and even in northern China.

More often than other regions in Russia elks fleas are found in Pskov, Novgorod, Kaluga, Leningrad, Tver, Yaroslavl and Vladimir regions. The number of insects directly depends on the number of moose and deer in the territory.

Elk Fleas - photos

This insect does not look like a fly, except that it has wings. The deer bloodsucker has this peculiarity: after it hits the body of a new victim, it drops its wings and fastens itself to the hairs of the victim. Now the insect becomes like a tick, although it is not a relative.

Elk fleas have a flattened body, and the size of the insect is from 3 to 3.5 mm. On the flat head there are two large eyes occupying ¼ of the entire surface of the head. But apart from these big eyes, the insect still has three simple eyes. Mouth in insects is a hard short proboscis. The legs of the bloodsucker are strong, with tenacious claws, thanks to which they cling tightly to the victim. The wings are transparent, reach a length of 6 cm, which is twice the length of the body itself. However, elk fleas fly very badly and only for short distances.

In order for the bloodsucker to make a flight, a good reason is required. This is caused by the smell and warmth of an approaching moose or deer. Hunted insects only during the day when it is light. Clinging firmly to the victim, the pseudo-cheek throws off her wings without regret, so as to freely burrow deep into the victim's hair.

What's next?

Up to three weeks the insect leads a full and sedentary lifestyle on its victim. After this period, it becomes sexually mature. Interesting is the fact that the bloodsuckers stick with the partner together, to find a pair on one animal is not at all difficult. Sometimes there are up to three hundred insects on the victim! The fertilized female brings offspring 15-20 days after fertilization. She lives up to 6 months and during this period is able to give life to 30 new individuals.

Young pupae, covered with a hard shell, fall to the ground. This happens for the period from October to March. Until August, the insect is in this condition, and then turns into a young fly.

Bites

The bite of the bloodsucker hurts, and at one time sucks up to 1 mg of blood. Trapeznichat an insect for a day can up to 20 times. How much blood the animal loses in a day, having up to 300 bloodsuckers on its body! Young horsemooters often lose their development due to loss of blood, and animal hair is very dirty due to feces excrement. The place of the bite turns red, a dense knot appears on it, which does not last until 20 days.

A fly is a small insect that looks like a mite. It is familiar to all who are in the woods in the second half of August - early September. It is at this time that elk lice are the most common.

Extensive of these insects. They are distributed practically on all European and Asian territories, in Siberia, Scandinavia, China. They are also found in North America and in North Africa. In other words, elk lice, photos of which are presented in the article, dwell everywhere - except for the south, but in forest land.

The calf deer's calf is flat, light brown, sometimes slightly darker, glossy, 3-4 mm long and 2 mm thick. Abdomen can stretch depending on the amount of blood drunk. Legs with thickened hips, powerful and tenacious, with sharp claws. The head is large, round with two large eyes located on each side and three small in the center. An acute proboscis is able to pierce even an animal. On the back - 5-6-mm wings.

Having attacked the victim and buried in his hair, elk lice drop their wings, independently breaking them at the very bottom, thereby cutting off the opportunity to change their master. Insects pierce the skin and begin to suck blood, and after they are satisfied, they are looking for a partner for mating. Already in half a month after the start of nutrition (and they eat up to 20 times a day, each time sucking up to 1.5 ml of blood) the female is ready to produce offspring. Throughout the winter, until the beginning of March, the female gives birth to new insects. Elk lice are viviparous insects, eggs and larvae develop right in the mother's body, and she lays off a pre-pupal 3-4 mm in size, which then hardens and falls to the ground. For life on the body of a breadwinner, the female is able to postpone up to 30 pre-pups, from which a new generation will hatch by the fall. Insects that do not find their master, die for the winter.

Elk lice, unlike ticks, are not carriers of diseases. There are no agents of tick-borne encephalitis in them.

People are not particularly afraid of these insects, often taking them for small flies. Although the bites of these creatures are quite painful. Most often they bite open spaces - the neck and the lower part of the head.

Even though these insects do not carry danger, given that they can hide in clothes for a long time, after a hike into the forest it is necessary to conduct a thorough examination of the body and the things that have been put on. Hair must be combed comb with densely located teeth.

Kind time of the day, kamarads!

Summer ends and some "not our brothers" and very small creatures have started active breeding ... and (or) raising their own quarters for the winter ... ;-) In this case I'm writing about a creature that in the central part and in the north of the European part of Russia is called VINTAGE STICK.

Choosing the other day on nature, we wandered to a marshy slightly patch of forest and scared off a couple of moose ... My friends were happy about this circumstance, but I slightly stiffened and advised the people to "hide" whenever possible. And it was not in vain ... Very soon we were visited by a small flying creature in no small number, but through a masked grid we were not spit on!

True, after passing this part of the forest, and having already sunk into the field (to a good midday sun) from the last insects, we got rid only after a kilometer and a half.

In my opinion, this creature is worse than a tick, because it is not so easy to fight with it as with a tick (put on a suit, sprayed a repellent - you are all in the house, and if not so categorically, a simple mutual inspection saves even an unprepared tourist) . Here everything is different ... One salvation is the hood of a suit with a net and all the cuffs on a knitted broad elastic band (like sports jackets or socks), since this insect breaks through a simple sleeve with a stretch under the elastic band through the crevices formed by fabric folds ... And getting into your clothes will start moving around and bothering you worse than an ant ... You can also use elastic bands (often on "fuckers" sell for skaters and cyclists) for tightening (compaction) the bottom of pants and arms.

A moose louse is an insect that is not widely known to the public, although many have met with it quite often, just confused it with a tick ...

In fact, elk lice are many places where elk, roe deer, deer are found since August. They often get into your hair, where it's very hard to pull them out. Elk louse has a flat body, thick, tenacious paws, and also a proboscis with which they are able to pierce the skin and drink blood.

Elk lice have other names - elk flies or elk mites, but scientifically they are called "deer bloodsucking". In fact, they are adapted to life on the moose, getting on them, they drop their wings and live for their own pleasure.

And for a person elk lice get by accident, that's why they die very quickly, but until this point they are scared! There are no cases of transmission of any diseases with elk lice, so they should not be feared ... So doctors assure. But these insects are very unpleasant and even bite rather painfully. At the site of the bite of a moose louse, redness may appear, and the bite may be itchy (the kind of wound and the place around it looks like what remains after removing only the tick, which has not yet pinched your blood, by the way, that's why a louse, discarded wings, are often confused with a tick). If after a bite you have SUCH manifestations, then it is necessary to use an antiallergic drug that will help to remove the itching and redness.

Well, I repeat: to protect yourself from insect attacks, it is necessary to wear clothes that cover all areas of the body and have suits or cuffs, and wear a headdress on your head or tie a bandanna (scarf), neck a scarf (tuba, bandana or scarf) then these insects will not be terrible for you.

Elk louse is an insect that is not widely known to the population, although many have met with it quite often, just confused it with a tick. In fact, such elk lice are many, especially in the forests, starting from August. They often climb into the hair, from where it is very hard to pull them out. Elk louse has a flat body, thick, tenacious paws, and also a proboscis with which they are able to pierce the skin and drink blood. Elk lice have other names - elk flies or elk mites, but scientifically they are called "deer bloodsucking". In fact, they are adapted to life on the moose, getting on them, they drop their wings and live for their own pleasure. And for a person, elk lice get by accident, so they die very quickly. There are no cases of transmission of any diseases with elk lice, so they should not be feared. The only thing - these insects are very unpleasant and even painfully bite. On the site of a moose louse bite, redness may appear, and the bite may itch. Therefore, sometimes it is necessary to use an antiallergic drug that will help to remove the itching and redness. To protect yourself from insect attacks, it is necessary to wear clothes that cover all parts of the body, and put a hat on your head, then these insects will not be scary.

Deer bloodsucking is confused with ticks, because hitting on the body they drop their wings, and claws cling to their hair. To the mites Deer bloodsuckers have nothing to do with.

Distribution [edit] edit wiki-text]
Deer bloodsuckers live in a vast territory that includes the north of China, Siberia, and the European part of Russia. There are a lot of them in Scandinavia. Brought to North America. The number of reindeer bloodsuckers is directly related to the number of moose and deer.

Appearance [edit] edit wiki-text]

Lipoptena cervi without wings
It is strongly flattened with dense leathery shiny coverlets of a light brown fly color. Due to the dense cover and flattened shape, the blood-sucking body can withstand strong pressure. The length of the winged body is 3-3.5 mm. The head is directed forward and also flattened, the antennae are located in deep depressions on the forehead, practically not protruding above the surface. Quite large eyes, composed of 2.5-3 thousand facets, are located on the sides of the head and occupy up to 25% of its surface. In addition to complex eyes, this species has a bloodsucker on its head with 3 simple eyes. The oral apparatus is a piercing-sucking type, similar in structure to the proboscis of a flies of autumn ezhgalka. On the sides of the flattened chest are strong, with thickened hips legs, surmounted by asymmetric claws. Wings are well developed, transparent dense, with a small number of veins, 5.5 to 6 mm in length. The covering of the abdomen is elastic, so when feeding and "pregnancy" the abdomen can greatly increase in size.

Life Cycle [edit] edit wiki-text]
Females give birth to several larvae ripe for pupation, one after considerable intervals of time (they develop in the abdomen of the female in the uterine expansion of the oviduct, where a pair of glands opens, secreting a nourishing secret). In late August - early September, larvae mature. By this time, young individuals have wings.

Attack on people [edit] edit wiki-text]
Many authors have reported on the attack of deer bloodsucking on people, while the attack can be massive. So, when counting on a person in the Vologda region, the number of attackers of the bloodsucker sometimes reached 75-120 copies. for 1 minute. Attack of the wingless bloodsucker is carried out by hunters, who trim elk, roe deer and deer. Particularly attractive for these flies are moving people. In all likelihood, the size plays an important role in the choice of the object of attack. So, it was noticed that children under the age of 7-8 years are rarely attacked by bloodsuckers, and if there are adults near the child, it is very rare. After flying on a man, the bloodsucker remains motionless for a few seconds, after which he begins to move quickly, usually upwards, trying to get into the hair or under the clothes. In this case, flies are not afraid of scaring off sudden movements and do not leave the object. Moreover, removing the bloodsucker is not so easy, because it has a flat body with hard smooth covers and legs armed with tenacious claws. Having settled in hair or under clothes, flies proceed to bloodsucking, sometimes not immediately, but after some time (30-60 minutes). The sensations that people experience when biting deer bloodsuck are different: some consider them painless, others - more sensitive - experience pain, sometimes severe, accompanied by burning and itching. Skin manifestations are also different and depend on the individual congenital and acquired sensitivity to the saliva of the bloodsucker. It is noticed that people who have been bitten for several years, the skin reaction is stronger and the consequences of bites are heavier.

It happens that at first the bite of the deer bloodsucker is barely noticeable, so it is difficult to see the food place after the insect has left the host; but after a few days an itchy small dense, slightly raised above the skin bundle (papule) appears on this place, which persists for 15-20 days. In another laboratory experiment, after bite of the deer bloodsucker, a slightly reddened stain appeared first on the skin without any swelling, surrounded by a red ring. After 2-3 days, a secondary skin reaction occurred at this site, which lasts up to 2-3 weeks and is characterized by itching, which occurs both during the day and at night, but without raising the temperature. Observation of cutaneous lesions in 333 patients fed with L. cervi allowed AF Chistyakov (1968) to identify and describe 4 types of dermatitis: in most patients (138 people), after a sting of the bloodsucker, a macular rash was observed, sometimes with a crust that disappeared without a trace in 4-5 days. 84 people had a papular rash with a crust and severe itching, healing came in 10-12 days. At 44 people after a while (from 40 minutes to 24 hours) after the sting, blisters formed at the injection site, while all of them had an elevated persistent red dermographism. And, finally, in 67 years, no rash was detected during 67 years after bites of L. cervi, and then, in response to the bite of the bloodsucker, the inflammatory exudative nodes of red of various diameters (up to erythema) developed, the treatment of which took 5-6 months see also Hippoboscidosis, Entomoses).

Epidemiology [edit] edit wiki-text]
It should be taken into account that the deer bloodsuckers feed on the blood of the same species of animals that are the feeders of adult ixodids and occupy the same area as the main carriers of Lyme disease, and also that various types of dermatitis develop on the human skin, including erythema, accompanied by inflammatory, sometimes not long, phenomena, as well as indications of some authors for cases of non-nutritional parenteral infection with Lyme disease. Investigations of the intestinal contents of the bloodsucker and the conduct of an enzyme-linked immunosorbent assay using monoclonal antibodies to detect the causative agent of Lyme disease in ticks (Burakova, 1999) have shown that at least 27.6% of hungry winged reindeer breeders contain spirochetes, the causative agents of Lyme disease.
