One of the most extraordinary partnerships between an insect and the plant that it pollinates is that of the yucca and the yucca moth. They are so interdependent that one cannot live without the other. Actually, there are a number of species of yucca, each with its corresponding partner, a species of Tegeticula or Parategeticula moth. This mutually beneficial relationship probably started as a relationship of exploitation with the moth feeding on the yucca.
