The observation of the world of insects can be compared to the discovery of a universe in which the laws of physics do not have the same effects. In this world, for example, it is possible to walk on the water or to fall without the risk of injury. But the animals that populate it are still more amazing. Some of them seem to  be designed by the unbridled imagination of an author of science fiction novels. They even give trouble to entomologists who try to classify each species in an order, a family, a genus.
