The leak in the house coincided with overnight rain, just when the number of confirmed cases in the United States exceeded 1.2 million, 2020 added drama to the American people, and it is still a horror movie.
Recently, according to a number of media reports, the "killer hornet" invaded the United States.

killer? bumblebee? invade? Did the Autobots mutiny, or did the creatures mutate?
Invasion naturally refers to species invasion, and the "killer" refers to The Asian giant hornet, also translated as the Great Tiger Head Wasp.
Originally living in Asia, it appeared in North America last year, and is suspected of species invasion. Its image is like the villain in the comics, with tiger black and yellow striped skin, which is not easy to look at:
The great tiger-headed bee is unusually large, with a body length of 4 cm, and looks like this at close range:
This is the size comparison of the collation in the network, and its tonnage is basically crushed:
The spines on the "ass" are 6 mm long and can inject a large amount of venom, which can reach a 7 times higher venom dose than that of the native Bee in North America.
Its diet is also wild, including medium to large insects in addition to sap and honey, and even preys on bees, other species of bumblebees, and praying mantises.
At the same time, as the giant wasp embarked on a hot topic, there are still videos circulating on the Internet these days that it and the rat fight, Tom Cat watched the direct call "insider":
Large, able to fight, with stingers, poisonous liquid, dozens of people die of it every year in Asia, and these labels also make the big tiger head bee wear the flower name of "killer bumblebee".
But it is too early to say that it will begin a large-scale invasion of the United States now.
According to news reports, the big tiger bees, which originally lived in parts of Asia, were found to have appeared twice in Washington State last year, and no one knows how they crossed the ocean to North America, most likely hitchhiking in containers.
But researchers worry that if they can't be controlled in the next few years, they are likely to multiply.
So the problem is, only found twice, this is not a large-scale invasion at all, what is there to be nervous about?
For example, in 2004, the Asian "ink-breasted wasp" entered France, spread to Spain in 2010, spread to Belgium in 2011, and then spread to Germany and the United Kingdom in less than 5 years, spreading quite quickly.
So American scientists worry that if not defended in time, the big tiger bee may spread throughout Washington State and beyond.
When they settle down, they can fly 9 kilometers or more away from the hive in search of food, a process that is likely to pose a threat to American bees and natives.
Threats to people are well understood, and although the tiger-headed bee usually does not attack people, it will still choose to do it if it is threatened
It can even pierce the protective clothing of beekeepers, and the sting + venom will form an extremely painful combination, like metal piercing into the skin.
Foreign anchor Coyote Peterson once took the initiative to try the feeling of being bitten in the show:
After taking a bite, he rolled all over the ground, and said that the pain was similar to burning pain, and it was very persistent, the burning sensation lasted for 3 hours, and the pain lasted for nearly 36 hours. ,
The arm is swollen a large circle:
More than 50 bites can even threaten life safety.
John Swann, a Canadian entomologist, explains that being stung about 20 times may not be life-threatening except for pain, but after 50-60 times it is dangerous. And the wasp itself will repeatedly attack the bite, and even release pheromones to attract the bee colony and call on more brothers to launch more attacks.
Of course, if you are allergic to venom, you only need to come and have an allergic reaction, and then it is possible to hear the call of the professional team.
Although it sounds terrible, after all, the big tiger head bee will not take the initiative to attack humans. Compared to most people who are afraid of being stung by them, some beekeepers are the most upset, fearing that these alien creatures will destroy the local hive.
As mentioned above, the big tiger-headed bee eats a wide variety of insects and loves to eat bees.
The big tiger bee bullies the native bees of North America as if they were unmatched. When they encounter a bee, they attack the bee with their jaws and bite their heads off. A killer bumblebee can kill 40 bees per minute, and in an hour and a half, a group of killers can solve the worker bees of the entire colony.
When the "soldiers" are annihilated, these killers occupy hives, feed on the larvae, and feed food to their children.
It sounds like the destruction of small bees, but in Asia, the Japanese bees that live with bumblebees have the ability to resist enemies.
They lure the big tiger-headed bee into the hive, which then swarms up, trapping it in the middle of the bee ball:
Then by increasing the temperature inside the ball to turn the defense into an attack, the counterattack is achieved.
But the problem is that the American bee farms use European bees, and they have not evolved this coping technique at all, and they are helpless in the face of "killer wasps", which is the terrible thing about species invasion.
So after finding the traces of the big tiger head bee, the scientists decided to take action immediately. The Washington State Department of Agriculture not only calls on people to be careful of the big tiger head bee, but also asks the public for track information, not only to search comprehensively, but also to set traps and prepare to hunt the big tiger head bee.
Because April and May are the time for them to nest, spread, and reproduce, they strive to nip this invasive species in the bud.
Although the big tiger head bee is notorious, some scientists do not think it is necessary to worry and panic too much.
Because the great tiger-headed bees seen in the United States last year were all isolated, floyd Shockley, the insect collection manager at the National Museum of Natural History, believes that these isolated reports are not enough to constitute a conclusion about a full-scale invasion.
In addition, many entomologists believe that the nickname "killer" is also exaggerated, people go out to hunt and eat, rather than specifically to kill people, which may lead to excessive fear of insects.
Speaking of eating, the Japanese netizens next door may have drooled, because in some parts of Japan, it is said that this bumblebee is both a threat and a delicacy, including barbecue, soaking wine and so on...
But obviously American netizens will not have such a good appetite, many people have mixed emotions, both excited and helpless, after all, the epidemic has not gone, and ushered in this uncertain "bomb".
Of course, some people are numb: the epidemic diagnosis has exceeded one million, who cares about these bugs?
Even some netizens began to speculate about what the next wave of doomsday news would be. For example, some people say that land sharks will appear:
Door-to-door cannibalism:
There is also the undersea Tyrannosaurus rex, which dominates the sea:
There are also predictions that it will be sand sculptures, which will attack humans from the sky in June:
Some netizens feel that the next time will be the ultimate judgment:
In short, now foreign netizens are frequently asking: Can 2020 be worse?
In the darkness, there seems to be a voice that tells everyone about the irregular updates like a series:
It's possible.
