After the yucca moth lays her eggs, she marks the flower with a pheromone, letting other moths know the flower is “taken.” After about a week, the small, pinkish-red caterpillars hatch inside the ovary and begin eating the immature seeds. The paper "Symbiotic Relationship between Yucca Plant and Its Moth" highlights that symbiosis between plants and animal species is both a one-way and two-way traffic. They are so interdependent that one cannot live without the other. They have developed a symbiotic relationship and neither can live without the other. A key is that there are more seeds than one or two caterpillars can eat, ensuring that the yucca can reproduce, and the moth only lays one or two eggs so too many caterpillars won’t be produced per seed pod. What is the role of a yucca in a mutualistic relationship? In fact the yucca moth usually pollinates the plant by chewing into the flower and laying its eggs. There are many plants that have a special relationship with specific insects or plants, in a way that is mutually beneficial.

However, one of the most wonderful symbiotic relationships is between the Yucca tree and the Yucca moth. These plants generally grow in U. S. Department of Agriculture plant hardiness zones 3 through 10, although hardiness varies by species. Their lifespan is about a year, but most of it is spent in the pupal stage.

Without the Yucca the moth would probably die and without the moth the Yucca would not naturally produce seed. The yucca plant and the yucca moth both have a mutualistic, symbiotic relationship. This kind of relationship actually can be found fairly often since many plants and animals seem to have evolved together for this very reason, but this relationship is unique.
