“Trailhead” is a very engaging story by the biologist E. O. Wilson. Here is an excerpt from Trailhead,
“The Trailhead Queen was dead. At first, there was no overt sign that her long life was ending: no fever, no spasms, no farewells. She simply sat on the floor of the royal chamber and died. As in life, her body was prone and immobile, her legs and antennae relaxed. Her stillness alone failed to give warning to her daughters that a catastrophe had occurred for all of them. She lay there, in fact, as though nothing had happened. She had become a perfect statue of herself. While humans and other vertebrates have an internal skeleton surrounded by soft tissue that quickly rots away, ants are encased in an external skeleton; their soft tissues shrivel into dry threads and lumps, but their exoskeletons remain, a knight’s armor fully intact long after the knight is gone. Hence the workers were at first unaware of their mother’s death. Her quietude said nothing, and the odors of her life, still rising from her, signalled, I remain among you. She smelled alive.”
Additional excerpt for info and interesting science.
“[…] By the time the colony had reached its full mature size, two years after the nuptial flight of the Queen, it contained more than ten thousand workers. It was able, in the following year, to rear virgin queens, and males, and through them to give birth to new colonies. By that time the Queen was producing eggs at the average rate of one every fifteen minutes. Heavy and torpid, she lay in the royal chamber at the bottom of the subterranean nest, five feet below the surface, a distance of four hundred ant lengths. By human scale, the ant city was the equivalent of two hundred underground stories. The mound of excavated soil capping the nest added another fifty stories aboveground.”
“[…] Her visual appearance, her stillness, meant nothing. The Queen could have lain on her back with her legs held rigidly up in the air. She could have turned red, black, metallic gold, or any other hue or shade—it would not have mattered. The Queen had to smell dead in order to be classified as dead.”
