Trivia
In real life, only 8 species of big-headed ants can produce supersoldiers naturally. Scientists have successfully forced other species of big-headed ants, including Pheidole morrisii, to do so by over-exposing the larvae to juvenile hormone. In Cold Blood, it can be inferred that the first encounter with fire ants has caused an unusual surge of juvenile hormone in the local big-headed ant colony.
