Yucca
Ecology

Yuccas have a very specialized, mutualistic pollination system; being pollinated by yucca moths (family Prodoxidae); the insect 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. Certain species of the yucca moth have evolved antagonistic features against the plant. They do not assist in the plant's pollination efforts while continuing to lay their eggs in the plant for protection.

Yucca species are the host plants for the caterpillars of the yucca giant-skipper (Megathymus yuccae), ursine giant-skipper (Megathymus ursus), and Strecker's giant-skipper (Megathymus streckeri).

Beetle herbivores include yucca weevils, in the Curculionidae.
