When ants hang out

  Biologists focusing on ant research estimate that there are many types of ants in the world, with a total of 15,000 species. Since ancient times, ants have been regarded as industrious animals. For example, an “Ant and Grasshopper” in Aesop’s Fables says: In the summer, the ants are also busy hard, and in the cold winter, they will not Starving; and the optimistic grasshopper thought that it was spring every day, and only knew that he was happy and did not do any preparations … the
  ant gave the impression of “untiring” and “no need to rest”; this is not the case. In 2015, biologists performed experiments in artificial ants’ nests. They marked each ant, recorded the activity level of the ants with a camera, and finally found that two-fifths of the ants were “Walking around”, doing nothing. How can other ants in a hard-working group tolerate such “lazy” behavior? So the scientists continued the experiment and finally found out the truth. The experimenters removed 20% of the labor force from the busy ants. Within a week, they found that the vacated posts had been replaced by those ants who had been wandering freely. The scientists suddenly realized that they had misunderstood the “walking ants”. They were not “lazy”, nor did they have nothing to do or unwilling to do, because they were originally “workers for the shift.” Someone else thought of this idea: these “worker ants for the shift” were also removed; therefore, there were no ants to replace the vacated posts.
  Regarding the above phenomenon, the artificial intelligence technology experts made a supplementary explanation: For the ant kingdom, it is not necessary to let all laborers participate in every labor service operation. Too much behavior actually brings the risk of “adding traffic”, usually 30% of the ants can Complete two-thirds of all “work quotas”.
  Maybe the behavior of the little ants and the mechanism of the ant kingdom have not been fully understood by humans. There is an individual 2 cm long ant in Africa. It is found that this ant likes to hunt other insects of the order Heteroptera, because the counterpart is no less than an ant , And good at resisting, so the fight between prey and anti-prey is very fierce, sometimes even cruel. To deal with prey, 200 to 600 ants (army ants deformed by worker ants) are often dispatched. About 5% of the ants are injured in each battle, their legs are broken or they are bitten by the strong jaws of the opponent. Despite this, only four- or five-legged ants can continue to fight because there is an effective “ambulance” in the ant colony.
  After the battle, the injured ants sent a distress signal to the rescue ants with the scent, and the rescue ants would rush to send them back to the ant nest, first licking the wounds for the injured companion-a disinfection method. Sometimes, rescue ants will even use some parts of the body of a dead isoptera insect to “surge” an injured ant. The success rate of the operation is quite high. Surprisingly, severely injured ants (such as five out of six legs) will eventually refuse help from rescue ants: when rescue ants approach them, they will do their best to resist the rescue and force the rescue ants to abandon them .
  It seems that some species in the world really need to be studied carefully and make people look impressive.
