These moths are specific pollinators for the plant and the plant cannot survive without them. Both pollinating yucca moth (Tegeticula) and bogus yucca moth (Prodoxus) abundance increase with density of live Joshua trees. Yucca seeds provide the only food for the yucca moth larvae, so they need the plant to survive. Yucca moths typically lay about six eggs in a yucca flower. At the highest tree density, moth abundance was low despite high tree abundance; this was the highest elevation site at 2212 m (site 11), which had no successful sexual reproduction. The yucca plant and moth cannot survive without each other. The moth cannot complete the life cycle without the yucca plant. If a biologist were to experimentally add 12 moth eggs to a yucca flower, what would be the most likely result? So we invite you to find a yucca, and pull up a chair. Both Yucca plant and the moth cannot complete their life cycles without each other. The yucca-yucca moth relationship was first described in 1872 by pioneering entomologist Charles Valentine Riley, and has since become a literal textbook example of symbiosis. Most moths emerge from the soil between … The yucca moth is well-known for its co-dependant relationship with the yucca plant. The first observation of the yucca moths was made by George Engelmann in St. Louis in 1872 (Engelmann, 1872). The yucca moth’s larvae rely exclusively on the seeds of the yucca plant as a primary food source, and the plant relies exclusively on the yucca moth for pollination. Answer: The realtion b/w moth and yucca plant is known as mutualism,becoz both Moth and Yucca plant benefit each other. The moth lay their eggs at the base of the flower where seeds are present. [xiv] Robert H. Webb et al,“Dynamics of Mojave Desert Shrub Assemblages in the Panamint Mountains, California,” Ecology , … The Yucca Moth and the Soapweed plant have an interesting relationship that is necessary to both of them. Baker (1986) provided a passage from Engelmann’s notes written on 13 June 1872 about the initial ob- The best time to view moths in yuccas is just after sunset. The moth deposits its eggs in the locule of the ovary and the flower in turn, gets pollinated by the moth. The yucca plant, which Native Americans used to make baskets, has a mutualistic relationship with the yucca moth. The yucca plant … Engelmann asked Charles Ril-ey, then state entomologist of Missouri, to explore the relationship between the moths and the plants. The larvae of the moth come out of the eggs as the seeds start developing. It is a balanced relationship – the moth pollinates the plant and in exchange the plant provides food for the moth. The female yucca moth acts as the pollinator of the yucca plant. The state flower of Mexico owes its existence to insects. Tegeticula is commonly known as the yucca moth. Moth larvae feed only on Soapweed seeds, and in turn the Soapweed is only able to produce seeds if the plant is pollinated by Yucca Moths. Since the larva develops into a moth that pollinates the yucca plant, the relationship is clearly beneficial to both partners. They share a mutually beneficial relationship. Moth lays eggs on Yucca plant.The eggs of Moth take food and shelter on Yucca plant.On the other hand the pollination of the plant is done by Moth.These eggs get hatched on the plant.Once the pollination is done the larvae of the Moth gets free. By comparison, the relationship between the Mexican jumping bean (Sebastiana pavoniana) and its symbiotic moth (Laspeyresia saltitans) is clearly one-sided.
