On exactly one night in its entire lifetime, the yucca moth discovers pollen in the opened flowers of the yucca plant, forms some into a pellet, and then transports this pellet, with one of its eggs, to the pistil of another yucca plant. This activity cannot be "learned"; it makes more sense to describe the yucca moth as experiencing intuition about how to act.^[24] Archetypes and instincts coexist in the collective unconscious as interdependent opposites, Jung would later clarify.^[11][25] Whereas for most animals intuitive understandings completely intertwine with instinct, in humans the archetypes have become a separate register of mental phenomena.
