The scientific or taxonomic name would be Prodoxidae.
The yucca moths belong to the family Prodoxidae in the order Lepidoptera. The genus Tegeticula and Parategeticula are the two primary genera of yucca moths.
"Yucca" is the genus part of the scientific name (Genus, species).
The Yucca Moth lives in the southwestern United States, Mexico, and the West Indes. Yucca Moths have a symbiotic relationship with the Yucca plant, they can not exist without each other.

Yucca Elata
The yucca moth lives on the yucca plant and does no travel to other flowers or plants. Adult moths live inside the flowers and the larval stages are all completed inside the yucca fruits as they develop.
The yucca moth is associated with the yucca, a flowering plant, mostly found in Mexico and the southwestern United States. When mature, yucca pollen grains form sticky masses, which pregnant female yucca moths collect with long appendages (called maxillary palpi) from their mouth region, form into balls, and transport. When ready to lay her eggs, she crawls into another flower, and lays her eggs inside of an ovary of the flower. She then climbs to the top of the ovary, and presses the pollen into the central stigmatic depression. In doing so, she ensures the pollination of the flower in which she has laid her egg. The germinating pollen grains fertilize hundreds of immature seeds inside of the plant, some of which will provide food for the larvae as it matures. Both the yucca plant and moth are dependent on this pollination regime for survival.
Yucca is a genus of perennial shrubs and trees in the family Asparagaceae.
The scientific name for the Joshua tree is Yucca brevifolia.
It's a mutualistic relationship. The yucca plant (Mexico, Caribbean and Southern US) can't pollinate itself to grow more seeds. The yucca moth pollinates the plant and lays its eggs inside the plant. When the moth larvae hatch, they feed on the seeds of the yucca plant, but the plant only lets a certain number grow, so that they don't eat all the seeds. So by pollinating the plant, the moth develops food for its larvae and the plant as well as the moth can survive and continue. And the adult moths emerge from their underground cocoons exactly when the yucca plants are in flower, in early summer.

The accepted scientific name is Tegeticula yuccasella.
