Why do old people always say that matchmaker can't touch? What is a matchmaker? Can you talk about it?

Children in rural areas like to go up the mountain to pick fruits, but it is useless for adults to warn them when they go down the river to touch the edge. Besides, children in rural areas also like to catch insects to play with, such as dragonflies, butterflies and cicadas, and they can't escape from the palm of a group of monkeys. However, no matter how bold the rural children are, they dare not provoke the matchmaker. What's going on here? What insect is the lady in red talking about? What's so special about him that monkeys in the countryside are far away from him? In fact, the matchmaker we are talking about is not an insect, but three winged insects: spotted-winged cicada, black-winged, brown-winged and matchmaker. Among them, spotted wax cicada is the most famous. It has a soft spot for Ailanthus altissima and will attract the attention of its peers at a fixed time. The spotted wax cicada is called matchmaker. What is so powerful about it? Is spotted cicada as poisonous as flying insects?

We know that there is an agreement in nature, commonly known as hidden rules. The brighter the colors of animals and plants, the more dangerous they are. Like mushrooms in the deep mountains of Yunnan, they are beautiful, but they are also poisonous. Therefore, whether it is a donkey friend who goes on an adventure in the wild or a tourist who goes out for an outing, when he sees the colorful Zen statues, his conscious reaction is to stay away. Before the spotted wax Zen grew up, its black body was covered with white spots. When it is mature, you can see a bright red under its wide wings. I have to say that cicada grew up and wished the whole world knew that he was not easy to mess with. So it is no wonder that old people always remind their children to stay away from Ailanthus altissima. After all, Ailanthus altissima is Bayilachang's favorite food. Every May and June, Ailanthus altissima, Elm and Solanum nigrum are covered. They just stick to the bark and suck the leaves. This scene makes people feel numb. In fact, people don't regard him as gorgeous, but this is just a disguise of the spotted cicada. It is actually a non-toxic insect, without any poisonous glands, fangs and toxins, and poses no threat to human health. But its body odor is so bad that it can't be washed away for a long time. In addition, infection with bacteria may be bad for it, so it is better for everyone not to touch it.

Of course, there are holes in the wind. Although the matchmaker of spotted wax cicada is non-toxic, the matchmaker with black wings and brown wings is not so easy to talk to. Their bright red color is not a fox, but really used to remind other animals that it is highly toxic, mainly distributed in central and southern China. Buried in the ground, they all look the same, and there will be obvious differences in adulthood. You can't touch it easily with your hands. They secrete a venom called cantharidin. 35 mg of cantharidin can cause death and is very dangerous. It can only be said that fortunately, the body fluid secreted by the black-winged brown-red Zen contains less cantharidin, and people will not die if they touch it, but they will feel uncomfortable. If people scratch them with their bare hands, their skin will burn, even blister, and in severe cases, they will bleed locally, so if you want to scratch them, you'd better wear gloves.
