Slave ants living in South America made their living by plundering and raising slaves. Slave ants are very strong ants, they do not distinguish between soldier ants and worker ants, almost all worker ants have become soldier ants. Lazy but aggressive, slave ants break into the nests of other ants by waging wars, plundering the larvae of other ants and raising them into their "slaves". The heavy work of foraging, raising larvae, cleaning, etc., is done by "slaves", and slave ants maintain their luxurious lives by constantly waging wars.
There is a slave ant called the red ant, which is so lazy that it has even lost its independent life. They would rather starve to death than open their mouths to feed themselves, and even if the food is in front of them, they will be "slaves" waiting to feed it.
In summer, you can often see swarms of ants fighting together, killing all the time. Why are ants so belligerent? It is because ants have a special smell, they can distinguish whether they are their own people through the taste, if not, they may fight. If you remove the smell of the ants that are fighting, they will walk away safely. If you put some perfume on an ant, it will definitely be driven out.
Ants are good partners with aphids, which secrete "milk" under the massage of ant antennae. There is a black tree ant, the "milkman" responsible for massage accounts for 15% to 20% of the total number of ant colonies, and there are about 20,000 black tree ant families on the roots of an old tree, and they can get up to 5,000 ml of "milk" secreted by aphids parasitizing legumes in one summer.
Stomafinav aphids are absolutely not found where there are no ants, and ants will even keep the overwintering eggs of the aphids in the nest, and in the spring, the ants will carefully escort the hatched aphids to the young treetops.
There is a species of leaf-cutting ant that lives in South America, and if they hit a fruit tree, they will use a large crocodile to cut the leaves of the tree, but they do not like to eat leaves, but they move the chopped leaves back to the nest, chew the leaves into detritus, pile up into a small mushroom house, and soon a small mushroom will grow. When the mushroom grows, leafcutter ants will feed on the mushroom.
Incredibly, this small mushroom can only be seen in the nests of leaf-cutting ants, and without the help of leaf-cutting ants, they may have become extinct long ago. I don't know if anyone has eaten it, I don't know what the taste of this mushroom is!
