Yuccas have a very specialized, mutualistic pollination system, being pollinated by yucca moths ( family Prodoxidae ); the insect purposefully transfers the pollen from the stamens of one plant to the stigma of another, and at the same time lays an egg in the flower ; the moth larva then feeds on some of the developing seeds, always leaving enough seed to perpetuate the species.
