A genus of American liliaceous, sometimes arborescent, plants having long, pointed, and often rigid, leaves at the top of a more or less woody stem, and bearing a large panicle of The most significant genuses in the family are Agave and Yucca: Agave includes 38 species in the United States and about 200 species elsewhere, and Yucca includes 30 species in the United States and over 45 in Mexico and South America. Growing in the desert, the soaptree yucca plants have sharp sword-like spines pointing out in all directions. What do yucca moths pollinate? The yucca moth is a moth of the family Prodoxidae. Even at the end of the season, the last and only flower remaining on the stalk may be full of them. It seems to be a certainty that except in a very few instances the common Yucca filamentosa bears no seed except when the Pronuba yucca-ella makes itself at home in the flowers. Flowers are pollinated by the Pronuba Moth, which lays its eggs in the ovary of the yucca flowers. The Pronuba Moth, commonly called the yucca moth, is a small white moth that lives in the semi-arid habitats where yucca plants grow. The soaptree yucca and the pronuba moth depend on each other to survive (a dependency called mutualism). Yucca is a plant of the southwest- ern arid regions of North America, and Pronuba is a moth; and the two are very dependent upon each other. Now let us see how this partnership … Any of several small, white, North American moths of the former genus Pronuba (now Tegeticula, family Incurvariidae or Prodoxidae), which pollinate yucca plants; especially the yucca moth, T. yuccasella. There is a very special relationship between the soaptree yucca and a tiny, little white moth called the pronuba moth. Family: Agavaceae. For example, the pollinator of Mojave yucca ( Y. schidigera ) in the Mojave Desert and Y. filamentosa in Missouri is a white moth named T. yuccasella , while the pollinator of joshua trees ( Y. brevifolia ) is a dark gray moth named T. paradoxa . Tree Characteristics. Scientists have found up to 67 different kinds of insects on or using the soaptree yucca, but this moth is the only one that pollinates it. I’ve been trying to get one for a couple of years so I was very excited to see this yesterday. The yucca moth’s larvae rely exclusively on the seeds of the yucca as a primary food source and the plant relies exclusively on the moth for pollination. Domingo.] Growing in the desert, the soaptree yucca plants have sharp sword-like spines pointing out in all directions. The hindwings are medium to light brownish gray. The wingspan is 18–27 mm. The yucca moth family is a primitive one that is found worldwide, though not all Prodoxids are involved with yuccas. The moth then flies in circles until it catches the scent of the flower. It is concerning this excess of seed and the number of seeds eaten that data are submitted. Pretty cool, huh?! Email This BlogThis!
