yucca moth range

Yucca schidigera commonly grows with both banana yuccas and Joshua trees over much of its higher-elevation natural range. Moths lay their eggs in the ovary after fertilizing flowers. Not yucca moths: because their caterpillars depend on the continued existence of Joshua trees and their tasty seeds, the yucca moth’s pollination is an active act of survival. Yucca brevifolia Englem. However, if the moth does too much damage in the course of oviposition, it risks triggering the plant to abort the damaged flower. They are famous for an old and intimate relationship with Yucca plants and are their obligate pollinators as well as herbivores. Yucca Moth — Brian Hoffman courtesy of the Alberta Conservation Association and the Alberta Sustainable Resource Development. Ecologically, yuccas are adapted to a wide range of habitats from rocky deserts, grassland prairies, mountains, light woodlands’ coastal sands, and semi-arid subtropical and semi-temperate zones (4). This would occur if the environmental envelope of the moth's range does not extend as far as the Joshua tree's range, so that the number of pollinators is lower toward the range edges, resulting in lower numbers of fertile seeds and higher infertile seeds. When in bloom, all are easily recognized by their large, white, fleshy, bell-shaped flowers. Yucca plants are dependent on Yucca Moths for pollination. 2012, Hembry et al. yucca moths, because there is no other consistently successful mechanism of pollen transfer and because yucca moth larvae feed only on yucca seeds. 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. One such system, the Joshua tree/yucca moth interaction, is ripe for an exploration of its shared biogeographic history. The yuccas ( Yucca and Hesperoyucca ) contain about 40 species, with Yucca divided into three sections based on fruit type: the spongy-fruited section Clistocarpa , the fleshy-fruited section Sarcocarpa , and the capsular-fruited section Chaenocarpa . iii COSEWIC Assessment Summary Assessment Summary – May 2002 Common name Yucca Moth Scientific name Tegeticula yuccasella … There are several differences between the life cycle of this system and that of the fig–fig wasp system. The most significant departure from this pattern is the broad host range exhibited by the pollinating moth Tegeticula yuccasella , which utilizes seven host species (Althoff et al. CW69-14/290-2003E-IN ISBN 0-662-34126-0 Recycled paper. We compared the species distribution models of two Tegeticula pollinator moths that use the geographically widespread plant Yucca filamentosa. She then oviposits into yucca ovaries and subsequently … Yucca plants are masters of water conservation . Yucca brevifolia is a plant species belonging to the genus Yucca. The larvae feed on the seeds, but enough seeds remain to reproduce. The different closely related species, all of which are generally referred to as yucca moths, are difficult to distinguish without examination under a microscope. The yucca moth is well-known for its co-dependant relationship with the yucca plant. The female Yucca moth collects a ball of pollen and flies to another Yucca flower where she squeeze the pollen down the pistil. In this association, the female moth actively gathers pollen from yucca stamens. Moth insects found in the state of California. Yucca moths (Tegeticula yuccasella) are actually a group of more than a dozen different species of small, rather nondescript whitish-gray bronze tinged moths. When a female yucca moth visits a yucca flower for pollination, she will also back up to the base of the yucca flower's ovary and insert a sword-like egg-laying structure called an ovipositor into one or more of the six locules to deposit her eggs. Tegeticula yuccasella occurs throughout eastern North America whereas T. cassandra is restricted to the southeastern portion of the range, primarily occurring in Florida. big bend national park, texas.
