Formics collect their dead.
Formics are suspected to be controlled by a queen through telepathic communications. Formics are known to collect their dead, and this would be controlled by the queen. One of our questions should be, Why do the Formics want their dead? We know that they fertilize their oxygen production with the dead, but would there be more efficent ways? For the Formics, is fertilizing the land an honorable burial, or death ceremony?
