Le Jour des fourmis

The Day of the Ants, like its predecessor, has several connected plot lines, some of which take place in the world of humans; others among ants. A year has passed since the time of the first novel. 17 people, including several relatives of Edmond Wells, the pioneer of the deceased inter-species communication, are still trapped under an ant nest. Since a new queen has been in charge in the ant nest, the supplies of food given by the ants to the humans are growing increasingly smaller. Meanwhile, strange murders are happening in the city of Paris, when several producers of insecticides are found dead in peculiar circumstances with no explanation of how the murders were committed. A wolf-fearing police detective and a human-fearing woman, Edmond Wells's daughter, combine their knowledge in order to find out who or what is behind these murders.

Learning from each other

One of the central themes of the novel is that humans can learn a lot from the civilisation of the ants and vice versa. The people living under the ant nest are acting more and more like ants and thus reach spiritual enlightenment. Meanwhile, some of the ants from the nest discover religion, through humans, and start praising humans (or Fingers, as ants call them) as gods.

Humans are not the owners of the earth

In one chapter of Edmond Wells' Encyclopaedia of relative and absolute knowledge, the protagonist is asked about the best way to get rid of ants in one's apartment. Wells replies that there is no reason why one should consider himself more of an owner of his own flat than ants. He claims that merely buying something from another human doesn't mean that something is yours now - you have merely more rights to be its owner now than other humans.

Ants in this novel consider themselves the masters of the Earth and even claim to have been the cause of dinosaurs' became extinction. Meanwhile, cockroaches feeding from human trash consider humans their slaves.
