Notes of an Astrakhan naturalist. A few words about spiders

The species diversity of spiders in the Astrakhan region is very similar to the composition of arthropods in Kazakhstan and Kalmykia. The climate of the Lower Volga region is characterized by dry summers and relatively warm winters with little snow. In such conditions it is easy for southern poisonous arachnids to survive. In the Astrakhan region there are 6 species of poisonous spiders. There are even more species of spiders that are completely harmless and even beneficial to humans.

Population and species status

The number of camel spiders is estimated at 700-1000 species. There is no exact data on the population size, but in some years it increases so much that crowds of salpugs literally attack human houses, crawling into slightly open windows, doors and any cracks. Population density is quite low. Searches for phalanges throughout the day lead to the discovery of no more than 3 individuals.

In 2022, in the Volgograd region, animals multiplied so much in the area of ​​the Shebalino farm that they scared the local population. The Crimean salpuga often spoils tourists’ holidays, not hesitating to sit on top of vacationers around the fire. Those caught in such a situation are advised to remain calm.

Threat factors include destruction of biotopes, development of areas suitable for habitation, plowing of land for crops, overgrazing of livestock, destruction by humanity due to the fear of being bitten. Recommended conservation measures focus on the conservation of landscapes, including habitats.

The camel spider is a unique creature, aggressive and fearless. They are not afraid to attack opponents 3-4 times their size. Contrary to all the fables created around these animals, they are practically not dangerous to humans. If you still cannot avoid the bite, it is enough to wash the wound with antibacterial soap and treat it with an antiseptic.

Population and species status

The desert lifestyle of the phalanx spider does not allow us to accurately determine the prevalence of populations of its species. Solifugae have become the subject of many myths and exaggerations about their size, speed, behavior, appetite and bite lethality. Members of this squad do not have poison and do not spin webs.

However, these spiders do not produce such an anesthetic, and like most creatures with a survival instinct, they do not attack prey larger than themselves except in a defensive situation or to protect offspring. Due to their bizarre appearance and the fact that they make a hissing sound when they feel threatened, many people are afraid of them. However, the biggest threat they pose to humans is their bite in self-defense.

The Phalanx spider leads a frantic lifestyle and is therefore not recommended as a pet. The nomadic lifestyle sometimes brings the spider phalanx into houses and other dwellings. There is no reason for alarm, so the arachnid can be placed in a container and taken outside. There have been no recorded deaths directly caused by the bite, but due to the strong muscles of their chelicerae, they can create a proportionally large, lacerated wound that can become infected. Only one species, Rhagodes nigrocinctus, has poison, but its bite is not harmful to humans.

How dangerous are karakurt (black widow) bites for an animal?

Different animals react differently. For example, horses, camels and many types of rodents can die from the bite of karakurt poison.

Dogs, hedgehogs, reptiles and amphibians are almost immune to the attack of a dangerous spider.

Karakurt (black widow) is a spider that causes fear, and for good reason, a bite from its female can be fatal. To protect yourself, you need to take precautions and be careful. When in the habitat of karakurt spiders, it is recommended to keep a box of matches with you so that you can cauterize the bite site immediately after the attack.

Sak

Spiders of the middle Urals are not large in size. Females reach 2 cm, males no more than 70 mm. The most prominent representative of modern Bashkiria is a poisonous creature. It feeds on small insects and their larvae - aphids, mosquitoes, butterflies, flies. Found in dry places.

Description of appearance:

  • yellow legs, abdomen;
  • cephalothorax red or bright orange;
  • chelicerae in the form of claws, fangs;
  • pedipalps reach half the length of the front legs.

It bites a person in defense of its own life. The bite is painful and causes a local allergic reaction - swelling, redness, pain, swelling. Children and people with weak immune systems experience a deterioration in their health. Body temperature rises, nausea, headache, vomiting, diarrhea. Special therapy is required.

Typical types of spiders in Bashkiria are not poisonous, but they bite painfully. The marks disappear in 7-14 days. In total there are about 24 families, 457 species. Cross spiders, side walkers, house spiders, hay spiders, canopy spiders, wolves, miturgids, grass crab spiders, etc. are often found. Predators bring great benefits to nature - they regulate the number of pests of forests, fields, and agricultural crops

Bites occur rarely, due to negligence on the part of a person or excessive curiosity

Where he likes to live in nature

European species of these spiders prefer desert and steppe areas with sparse vegetation. A favorite place is the shores of salt lakes, which are often found in Crimea. In coastal vegetation on beaches, in sagebrush thickets, in wastelands and along river banks, in ravines and in garbage heaps. They often settle in colonies. A characteristic feature of the home of a karakurt colony is a chaotic layer of cobwebs on the surface of the earth.

How to determine the habitat of this spider

Hunting animals of the Astrakhan region

The Astrakhan region is distinguished by significant reserves of hunting resources and has a variety of hunting grounds. Not only local residents hunt here, but also guests from other regions of Russia and from abroad.

The hunting fauna of mammals includes 18 species. Of particular interest to fans of sport hunting and commercial hunters are the hare, fox, wolf, muskrat and wild boar.

Calculations of the number and permissible norms for the removal of fauna objects classified as hunting resources on the territory of hunting grounds of the Astrakhan region are carried out by the Natural Resources Management and Environmental Protection Service of the Astrakhan region. These standards are communicated to hunting users. In accordance with requests from hunting users, this service sets daily standards for the production of hunting resources in a specific hunting season. Hunting is carried out within the time limits established by the decree of the Governor of the Astrakhan region.

The largest number of permits is issued for the production of fur-bearing animals; in 2017, about 4,000 permits were issued. Also, during periods of maximum numbers, permits are issued to regulate the number of active game pests and carriers of dangerous diseases (wolf, fox, jackal, raccoon dog).

The hunting resources on the territory of the Astrakhan region, in respect of which commercial hunting is carried out, include: ungulates - wild boar, saiga; fur-bearing animals - wolf, jackal, raccoon dog, common fox, corsac fox, otter, stone marten, steppe ferret, American mink, ermine, weasel, brown hare, yellow ground squirrel, small ground squirrel, muskrat, water vole.

Main commercial animals of the animal world

The most popular hunting mammal is the brown hare. In the region, the brown hare is found almost everywhere, and its numbers have been quite high in recent years, which is why the number of permits issued for its hunting is large.

The second most popular hunting object is the common fox. Due to the increase in food supply (mouse-like rodents, brown hare), the number of this representative of the animal world is also increasing. Just like the hare, the fox is distributed almost everywhere.

Active hunting for wolves is carried out in the Astrakhan region. This predator is a pest for farm animals, and during the hunting period it is allowed unlimited prey. The wolf is found almost everywhere in the region.

Muskrat catching is carried out on an industrial scale, up to 1000 animals per year.

Poaching

The most desirable animals that are poached in the Astrakhan region are elk and roe deer. Despite the fact that moose and roe deer are rare in the region and are protected by the Red Book of the Astrakhan Region, they are actively hunted.

In the Arkhangelsk region, state inspectors of the Natural Resources Management and Environmental Protection Service regularly conduct environmental raids, as a result of which dozens of cases (at the end of the year) of poaching of game mammals and violations in the field of hunting are identified and suppressed.

Sak

It also has other names - yellow, heyracantium. Poisonous spiders of the Kuban and Krasnodar Territory live in arid places and build burrows in the ground. They hunt actively at night. They run quickly, attack a victim several times larger in size, and win.

The spider is not aggressive towards humans, but it can bite in defense of its own life. At the site of the attack, an allergic reaction appears in the form of redness, swelling, and swelling. In young children and people prone to allergies, their health worsens. The condition returns to normal within a few days, the skin recovers within a week.

What to do if you are bitten by a karakurt

First aid

If you know for sure that you have been bitten by a black widow, then traces of poison should be visible at the site of the bite. This poison can be partially neutralized by thermal means, since the jaws of the karakurt bite through the skin by only half a millimeter. One of the most popular options is cauterizing the bite site with 2-3 match heads. This method was proposed by professor of zoology, entomologist and doctor of biological sciences Pavel Marikovsky. Place match heads on the affected area and set fire. It will hurt, but the poison under the skin will be partially destroyed. It is important to carry out this procedure no later than 2 minutes after the bite, otherwise the poison will penetrate deeper and not be destroyed. Also, you can cauterize it with any metal object very heated over the flame of a lighter.

Urgently to the hospital

You must immediately contact a medical facility. Explain to the hospital that there is a suspicion of a karakurt bite. Otherwise, you may be given an incorrect diagnosis with all the ensuing consequences.

The mortality rate from a black widow bite is 4-6% of those bitten. Children and people suffering from chronic diseases are at risk.

What victims of a black widow bite say in a Kazakh hospital

What is treated in hospital?

As a rule, the bitten person is left in the hospital, in the toxicology department or intensive care unit. Antikarakurt serum is administered. After taking the necessary medications, it will take some time to recover. Neurological consequences can last for several months.

  1. A certain diet is prescribed.
  2. It is advisable to drink more liquid.
  3. Limit your physical activity.
