Among them are two non-pollinating species of 'cheater yucca moths'. 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 Biologists have only recently determined that almost every species of yucca has its own species of yucca moth; some yuccas have two moth species. Greya subalba. North American Moth Photographers Group at the Mississippi Entomological Museum at Mississippi State University, 210044.00-0200.1. They co-evolved over millions of years, and maintain a mutual dependence. A species complex is a group of closely related, but distinct species of organisms that are so similar in appearance that it is often unclear in how to distinguish between species. Since greya moths are closely related to yucca moths they have become the subjects of numerous plant-insect coevolutionary studies. ; Reveal, J.L. Some species are accidental pollinators when carrying host plant pollen on their bodies. Ecologists long believed that one species of yucca moth (Tegeticula synthetica) pollinates both kinds of Joshua trees. Yucca moths are members of the family Prodoxidae and the genus Tegeticula. The adults are small with a wingspan between 4 and 16 mm and are usually dull colored, white, or gray. We used nuclear and mitochondrial DNA markers to examine genetic structure in a moth population where a cheater species is … This moth species is an obligate stem borer on the stalks of Soapweed. The tissue in the gall serves as the primary food source for the developing larvae. Prodoxus moths completely lack tentacular appendages on the maxillary palps possessed by the pollinating genera. The Yucca Moth family is a primitive one that is found worldwide, though not all Prodoxids are involved with yuccas. “Yuccas, Yucca Moths, and Coevolution: A Review.”, Chase, M.W. Tegeticula is one of the two genera of true yucca moth pollinators of yuccas. Contact … He became the first state entomologist for Missouri primarily to study grasshoppers and the grasshopper plagues of the American West between 1873 and 1877. The first recorded observation of yucca moths was made by physician and botanist, George Engelmann in St. Louis in 1872. She may lay more eggs in the flower’s ovary or yet fly to another flower, but before leaving, she marks the flower with a pheromone signaling to competitors that there are eggs already present for too many eggs will cause the yucca to abort the flower. If everyone who uses this resource gives a small amount, we could cover our ongoing costs, develop new features, and upgrade the system. 210044.00 – 0200.1 – Prodoxus decipiens – Bogus Yucca Moth – Riley, 1880 Photographs are the copyrighted property of each photographer listed. As a footnote, there are no common vernacular names for the listed species of moths, other than lumping them together and calling them “yucca moths.” The moth-plant relationship goes back at least 40 Mya (16). 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). They are most easily identified by their presence within Yuccaflowers. Finally the yucca-moth mutualism (living together in such a way as to increase each other’s reproductive success) is vulnerable to exploitation by cheaters: other moth species lay eggs within fertilized flowers but do not pollinate the flower. and Fay, M.F. Engelmann asked then Missouri State Entomologist, Charles Riley, to investigate the relationship between moths and yuccas. Such a tight mutualism has risks for both partners. Yuccas are only pollinated by th… © Copyright 2021, Sibley Nature Center. "Yucca moths" have a remarkable biology. Although dozens of other yucca moth and yucca plant species have similar relationships, the Tegeticula yuccasella andYucca elata,in the United States' … Add this Plant to your Plant List Please first create an account and name your plant list so you can access whenever you want. Alternative Title: Tegeticula. whitish moth that blends well with the color of the yucca blossoms where it spends most of its brief adult life The flowers on non-pollinated Email Address. Each spring, adult moths emerge from underground cocoons and the males and females meet up with each other on yucca plants to mate. The mature larvae emerge from the fruit and burrow into the soil for pupation (11). As a group, they are smallish and nondescript. All Rights Reserved. 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. One species, Parategeticula pollenifera, can be found in the pine-oak forests in southwestern Arizona, southwestern New Mexico, and Veracruz, Mexico, and is known to coexist with a member of the Tegeticula yuccasella complex. When the growing larvae have finished feeding on seeds, they burrow exit holes through the tissues of the fruit, drop to the ground, and burrow into the soil to complete metamorphosis within a cocoon (7). Some of them have larvae that feed on developing seeds. 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. One species endemic to Mexico, Y. queretaroensis, is listed under CITES Appendix II, which restricts international trade in this rare, endangered plant. Examples include: 1. Female yucca moth depositing eggs. An important plant for wildlife, it provides food and nesting for small mammals, birds, and reptiles. There are about 12 genera known, five of which occur in western North America with over 50 species (6). baccata. 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. Yucca moth, (genus Tegeticula), any of four species of insects of the Prodoxidae family of moths (order Lepidoptera). We need your help. Yuccas are actively pollinated by female moths in the genus Tegeticula that also lay eggs into the flowers. These small moths are typically white or gray and have relatively prominent maxillary and labial palpi that are shorter than the proboscis. 1997. Yucca is also native to the southeastern United States from Texas to Maryland. It is a host plant for the Yucca Moth. 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. You can download select species by searching or when you're on a Taxa page like Class, Order, and Family. 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. Compa… Two of the three yucca moth genera in particular, Tegeticula and Parategeticula, have an obligate pollination mutualism with yuccas. Moth larvae feed on the developing seeds. Prodoxidae. The Five-spotted Bogus Yucca Moth is known from only two sites in Canada, one of which was discovered in 2011. The moth family Prodoxidae is a primitive group, some of which were the first nocturnal moths. Pellmyr, Olle. Certain species of the yucca moth have evolved antagonistic features against the plant and do not assist in the plant's pollination efforts while continuin… The Yucca Moth is a relatively small, slender-winged brown moth with a whitish head. They are famous for an old and intimate relationship with Yucca plants and are their obligate pollinators as well as herbivores. 2. Several yucca species are protected in the states in which they occur. The key component of yucca moth habitat is the occurrence of yucca plants. http://tolweb.org/Prodoxidae/11872/1997.01.13 in The Tree of Life Web Project, http://tolweb.org/. Their bore holes are a common sight on trunks of such plants as the soaptree yucca. In the Southwest, one of their most iconic partners is the Joshua tree. In the central United States, soapweed yucca (Yucca glauca) is pollinated by a moth known as Tegeticulla yuccasella. Yucca moths (Tegeticula yuccasella) are actually a group of more than a dozen different species of small, rather nondescript whitish-gray bronze tinged moths. The yucca moth family. But greya moths lack the specialized behaviors and morphological structures characteristic of true pollinating yucca moths (15). “A Sub-familial Classification for the Expanded Aspergalean Families Amaryllidaceae, Asparagaceae, and Xanthorraceae.”. Birds and bats are common predators of … I am studying whether the pollination mutualism or the seed-eating antagonism is the major driver in moth specialization. Most Prodoxus species are smaller than Tegeticula, but one species, P. decipiens (elevated from Syn. 1999. 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. Yuccas are perennial shrubs and trees currently placed by many authorities into the family Asparagaceae and subfamily Agavoideae (3). They are small, white, and grub-like, turning pink to dark red with age. Prodoxids are members of the superfamily Incurvarioidea. 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). baccata Yucca baccata var.
