black widow spider
The Black Widow is a self-sufficient spider. She herself builds a web all her life and raises children. This name was given to the species for the peculiarity of the lifestyle. After mating, the female eats her man, and sometimes he dies a heroic death before fertilization.
The black widow is very prolific. Every 12-15 years there is an outbreak of the population of this species. This is especially true for those places where the winter is warm. These species have chosen comfortable places near people - landfills, heaps of garbage, industrial rubble.
Regions of residence of the black widow in Russia
Latrodectus mactans is the most dangerous species.
There are 31 varieties of black widow in total. However, in terms of toxicity, each has its own poison. The real deadly spider Latrodectus mactans lives only in hot regions of the USA.
Other species are less toxic. Arthropods prefer the warm climate of the Black Sea and Azov regions. Habitat - Kalmykia, Astrakhan region, Crimea, Krasnodar Territory, Southern Urals.
Not so long ago, data appeared on spider bites in such areas as Orenburg, Kurgan, Saratov, Volgograd, Novosibirsk. In 2019, black widows attacked people in the Moscow region. The consequences of the bites did not lead to death.
Distribution in Moscow and Moscow region
Spiders have the ability to travel in strong gusts of wind. The web is a sail. It is used to move long distances. This can explain their appearance in the suburbs. But there were no fatal bites.
It can be unequivocally argued that the spiders that have appeared do not belong to the most dangerous species. Scientists are inclined to believe that this is a species of Latrodectus tredecimguttatus. The content of neurotoxin in it is only 0,59 mg / kg. For comparison, in the species Latrodectus mactans (deadly) - 0,90 mg / kg.
