How do spiders survive the winter?

Spiders are the most abundant predatory natural enemies in terrestrial ecosystems, which can prey on some pests harmful to agriculture and play an important role in maintaining the stability of agroforestry ecosystems. There are many kinds of spiders. According to records, there are 3821 genera and 42055 species of spiders all over the world. So how do spiders survive the winter?

First, how spiders spend the winter

Spiders are generally divided into two kinds, one of which is the most common web spider, which hunts in webs between branches. The other is safari spiders, which wander around in search of prey. Safari spiders generally live in tropical, subtropical and temperate regions. Hunting spiders in temperate regions hibernate in winter. They find a corner or this is a hole and seal it with silk. And web spiders generally die after laying eggs in autumn and will not hibernate.

Spiders feed on insects, other spiders and polypods, and some spiders also feed on small animals. Web spiders usually trap insects that do not see filaments and do not have strong flying power. although the webs made by web spiders are very sophisticated, they can generally be woven within an hour. Although hunting spiders do not form webs, they can also spray spider silk. In storms, they can rely on silk to keep their balance and float to very distant places in the wind.

How to deal with being bitten by a spider

There are many kinds of spiders, some of which are very toxic. There are several poisonous spiders in China, such as bird-catching spiders in Guangxi, Yunnan, Hainan, red chelate spiders in Shanghai, Nanjing, Beijing, Northeast and other places, and burrowing tarantulas in Xinjiang, Shaanxi, Hebei, Changchun and other places, so what should we do if they are bitten by poisonous plants?

In case of being bitten by a spider, the most convenient and effective way is to burn the wound with matches or cigarette butts to destroy its toxins with high temperature. But this method must be carried out within 1-2 minutes after being bitten before the toxin spreads. In addition, you can also mash the ginger and apply it to the wound, or wash the wound with potassium permanganate solution, which can relieve and disappear the symptoms, or use 250 grams of traditional Chinese medicine Gentiana macrophylla, fried water as tea frequently. If the symptoms are very serious, it is best to go to the hospital for medical treatment.

That's all we have to say about spiders. More interesting knowledge about spiders still needs to be discovered by friends themselves.
