Why does the Western Blind Snake focus on larvae over adult ants?
Answer
To minimize exposure to active defenses such as formic acid or powerful mandibles.
Focusing on eggs and larvae is an adaptation to mitigate risk associated with feeding on highly organized insect societies. Adult ants, particularly in species common to the snake's habitat, are equipped with formidable defensive mechanisms, including powerful mandibles used for biting and chemical irritants like formic acid used for defense. By consuming the immobile, defenseless brood stages, the Western Blind Snake minimizes dangerous physical confrontations and maximizes the efficiency of its caloric intake.
