The flowers on non-pollinated Password. When the eggs hatch, the larvae feed on the developing seeds within the fruit; fortunately, there are more seeds than the larvae can eat. “Yuccas, Yucca Moths, and Coevolution: A Review.”, Chase, M.W. The yucca moth family. Systematic revision of the yucca moths in the. Even though they belong to two different kingdoms in the universe of life on our planet, the yucca moth species known as "Tegeticula yuccasella" and the yucca plant species known, popularly, as the "soaptree yucca" and, scientifically, as the "Yucca elata" have forged an inseparable bond. … Ecologists long believed that one species of yucca moth (Tegeticula synthetica) pollinates both kinds of Joshua trees. Likewise, Prodoxus use yucca as a host but without offering pollination services. The narrative follows that when a gravid female yucca moth is ready to lay eggs, she visits a yucca flower to collect pollen with specialized maxillary palp mouthparts called tentacles. The Five-spotted Bogus Yucca Moth is known from only two sites in Canada, one of which was discovered in 2011. baccata. North American Moth Photographers Group North American Stoneflies Odonata Central Orthoptera of the Northern Great Plains Orthoptera Species File Online Pacific Northwest Moths Singing Insects of North America (SINA) Trichoptera World Checklist baccata Yucca baccata var. 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). Studies in coevolution demonstrate how increased genetic variance between two different organisms with strong interactions can result in increased fitness for both. Like Tegeticula, the females of P. pollenifera have maxillary tentacles used for gathering pollen and actively pollinate its host plants, but unlike Tegeticula, the females possess a blunt ovipositor used to prepare a groove, usually in a flower pedicel, and lay a row of eggs.

Yucca moth, (genus Tegeticula), any of four species of insects of the Prodoxidae family of moths (order Lepidoptera). Among them are two non-pollinating species of 'cheater yucca moths'. Information on this Species is incomplete... Alberta Lepidopterists' Guild. Information on this Species is incomplete... Yucca Moth. Greya subalba. The Five-spotted Bogus Yucca Moth is known from only two sites in Canada, one of which was discovered in 2011. The moth larvae feed exclusively on developing yucca seeds. Prodoxids are members of the superfamily Incurvarioidea. Yucca Wild Buckwheat Eriogonum plumatella Eriogonum plumatella + Added; 6 Banana Yucca Yucca baccata var. Compa… Yucca is also native to some of the islands of the Caribbean. Only true yucca moths are known to pollinate yucca flowers. In the central United States, soapweed yucca (Yucca glauca) is pollinated by a moth known as Tegeticulla yuccasella. The pistil (female part) of each flower ends in a three-lobed stigma.In order for pollination to occur, masses of pollen must be forced down into this central stigmatic hole. They are most easily identified by their presence within Yuccaflowers. Yucca moths are members of the family Prodoxidae and the genus Tegeticula. Biologists have only recently determined that almost every species of yucca has its own species of yucca moth; some yuccas have two moth species. Prodoxidae. Email Address. Yucca is also native to the southeastern United States from Texas to Maryland. The word "coevolution" speaks to organisms or systems that have interacted in ways that have influenced their evolution over time. If everyone who uses this resource gives a small amount, we could cover our ongoing costs, develop new features, and upgrade the system. Most Prodoxus species are smaller than Tegeticula, but one species, P. decipiens (elevated from Syn. Range. Of the 80 or so species found worldwide, about 30 are native to North America. https://en.wikipedia.org/w/index.php?=Yucca&oldid=954950506, https://en.wikipediaorg/w/index.php?title=Species_complex&oldid=957323164, http://tolweb.org/Tegeticula/12419/1997.01.13, https://tolweb.org/Prategeticula_pollenifera/12420/1996.01.01, http://tolweb.org/Prodoxus/12422/1997.01.13, http://tolweb.org/Prodoxus_quinquepunctellus/12428/1996.01.01, http://tolweb.org/Prodoxidae/11872/1997.01.13, Pellmyr, Olle. P. quinquepunctella (eastern form) (13), is larger, white, and can easily be mistaken for some members of the Tegeticula yuccasella complex (14). Some of them have larvae that feed on developing seeds. For more than 40 million years there has been a relationship between yucca plants and yucca moths. Top When a female is ready to lay eggs, she first goes to a yucca flower to collect pollen. Yuccas are perennial shrubs and trees currently placed by many authorities into the family Asparagaceae and subfamily Agavoideae (3). Their bore holes are a common sight on trunks of such plants as the soaptree yucca. The yucca moths have a unique biology and are well-noted for their ancient relationships with Yucca ranging from obligate mutualism to commensalism to antagonism. The different closely related species, all of which are generally referred to as yucca moths, are difficult to distinguish without examination under a … 1997. In their native habitats, all these yucca species require pollination by a female moth of the genus Tegeticula (Pronuba). Additional Sources of Information Related to "Insects". Joshua trees are part of a highly specialized pollination relationship with yucca moths. Yucca Moths (Tegeticula yuccasella) are small white moths with a wingspan of 18-27.5 mm. Parategeticula are the other mutualistic pollinators of various Yucca species. Only true … Some species are accidental pollinators when carrying host plant pollen on their bodies. Riley and two California-based assistants, Albert Koebele and D.W. Coquillett are most noted for pioneering the principles of biological pest control, but they also had avocational interests in the microlepidopterans, including yucca moths (2). and Fay, M.F. Although dozens of other yucca moth and yucca plant species have similar relationships, the Tegeticula yuccasella andYucca elata,in the United States' … They are famous for an old and intimate relationship with Yucca plants and are their obligate pollinators as well as herbivores. Version 13 January 1997. It lays eggs on each pollinated ovary, and the hatched larvae eat some of the developing seeds. All Rights Reserved. The Yucca Moth family is a primitive one that is found worldwide, though not all Prodoxids are involved with yuccas. Usually, but not always, a species complex has a common ancestor. whitish moth that blends well with the color of the yucca blossoms where it spends most of its brief adult life Here's some links if you want to download a whole group. Moth larvae feed on the developing seeds. Two genera, Tegeticula and Parategeticula are known as “true yucca moths”; a third genus, Prodoxus, are “bogus yucca moths”, and a fourth genus, the closely related Greya (sometimes called greya moths) are of interest for plant-insect coevolutionary studies. Recently the species traditionally called T. yuccasella has been identified as being a complex of at least 13 species, many of which have very distinctive biology. The young larvae bore into the young fruit of Y. schottii and Y. elephantipella forming galls that replace several seeds. More recent morphological, molecular, and biological data show that T. yuccasella is instead a large complex of species that differ greatly in their biology (8). The first recorded observation of yucca moths was made by physician and botanist, George Engelmann in St. Louis in 1872. They are small, white, and grub-like, turning pink to dark red with age. The T. yuccasella complex is now composed of 10 newly described yucca pollinator species (altiplanella, baccatella, carnerosanella, cassandra, elatella, maderae, mojavella, rostratella, superficiella, and treculeanella) and two non-pollinating “cheater” species (intermedia and corruptrix) that oviposit directly into yucca fruit (10). Larval survival is dependent on the mutualistic relationship between the Soapweed and its pollinator Yucca Moth. Species: spp. Information on this Species is incomplete...

Interactions of these organisms range from obligate mutualism to commensalism to outright antagonism. Pellmyr, Olle. Over millions of years of coevolution, the yucca moth has come to depend exclusively on the yucca plant blossoms as a repository for eggs and on the seeds as a food source for its larvae, and the yucca plant has come to depend exclusively on the moth as an agent for pollination. The Yucca Moth is a relatively small, slender-winged brown moth with a whitish head. This moth species is an obligate stem borer on the stalks of Soapweed. The moths use these tentacle to collect balls of pollen from yucca flowers. The early developmental stages of the moth (the larvae, or caterpillars), are found inside Yucca flowers (also known as Soapweed), where they feed on developing seeds.
