Do Some Insects Believe in Keeping Slaves?
Yes, indeed, a kind of ants called sanguinary ants, attack the homes of other ants and take away their larvae. When they grow to become ants, the sanguinary ants force them to work as slaves, chewing food for their masters!
Some other kind of sanguinary ants send their queen into the nests of other ants. If this queen is able to kill the queen of the raided nest, she lays her eggs in the new nest. Those born from these eggs are then raised by the slave ants. Eventually, the sanguinary ants replace the other ants totally in their own nests!
