Empire of the Ants

Empire of the Ants (original title: Les Fourmis) is a science-fiction book written by Bernard Werber in 1991. It got a sequel in 1992, and another one in 1996.

It's about the Wells family, who have inherited a house from their dead uncle Edmond Wells, an eccentric scientist who was obsessed about ants and apparently discovered very strange stuff about them. In his will, he has left the instruction to "never ever go down in the basement".

Meanwhile, at an ant colony, a young male ant, 327, finds out that a whole group of ants got instantly killed under mysterious reasons. He tries to alert the ant colony, but they don't believe him. He decides to go investigate with a female ant, 16, and a worker ant, 103 683, suspecting the termites.

Tropes used in Empire of the Ants include:

A God Am I: A kid communicates with the ants and gets them into some sort of cult, leading them to believe he is their all-knowing god.
A.I. Is a Crapshoot: A computer becomes sentient in the third book and dead-set on fulfulling the will of its Knight Templar user, its very minerals becoming hostile to attackers.
Ant War: Especially the first book.
Artistic License: Biology: You should not take everything Werber writes at face value. Do you, for example, honestly believe a man could freeze himself to death just by believing he is in a cold chamber?
Belligerent Sexual Tension: Melies and Laetitia Wells.
The Cassandra: 327. The ants don't want to listen to him when he tries to warn them about the ant-slaughter he has witnessed, since he fails to bring proof. The ant MIBs didn't help.
Continuity Drift: An ant is described as laughing and doing humor in the first book; the following two ignore this and claim that ants do not know the concept of humor.
Famous-Named Foreigner: Subverted: the main family is named "Wells", but are French. A character also asks if they are related to H.G. Wells.
Humans Are the Real Monsters: Werber loves this trope: playing it straight and subverting it.
Humans Are Cthulhu: Obviously, when it happens through the point of view of ants, due to both the size and the culture difference between us and them. Throughout the series, the humans are referred as the "Fingers", since this is the part of us ants usually interact with. And when ants encounter human buildings, cars or others, they take them for Alien Geometries due to the sheer size and incomprehensibility of them. Oh, and the reason why so many ants got killed instantly in the first book's beginning? They were just stepped on by an old grandma. Then again, ants are sort of a little Cthulhu to humans, as well.
I Am a Humanitarian: When the human protagonists are stuck in the basement with nothing to eat, one of them decides that they should resort to cannibalism. They then get in a bloodthirsty fight. This also happens with an ant queen who is forced to eat her own eggs so that she has enough energy to lay an egg that can hatch.
Miranda Rights: The stories are set in France, but when Méliès goes arrest Laetitia, he recites the Miranda Rights.
New Media Are Evil: 103 693 manages to learn most of mankind just by watching TV for several days. Her verdict is not nice to hear. She has lots of nice things to tell too.
No Infantile Amnesia: The grandmother remembers when she was just born as she crawls through a wire tunnel.
Overly Long Name: 103 683 decides to just go by "103" in the third book, since her name is too damn long and she has been told the story of an ant who died because it took too long to call her from danger...
Reverse Psychology: How the Wells family go inside the basement. Edmond specifically told them not go go so that they'd go.
Shut UP, Hannibal: 103 683 gets in a fight with an ant who is sick of getting through many dangers just to bring a cocoon to humans. The other ant gets its head chopped off and makes a cynical, "The Reason You Suck" Speech to 103 683. The latter doesn't care much, and her comrad 23 interrupt the speech by kicking in the head.
Zerg Rush: the ants in general of course, but the Dwarve Ants as despicted as being especially good at this, due to them possessing multiple queen on each colony.
