I was born and raised in Amarillo. One of the most extraordinary partnerships between an insect and the plant that it pollinates is that of the yucca and the yucca moth. We ran across this interesting larvae (which we were unbeknownst to us a such). The larvae eat about half the approximately 200 seeds produced by the plant. The yucca plant and the yucca moth both have a mutualistic, symbiotic relationship. Yucca plants are dependent on Yucca Moths for pollination. RCA Records A conservation story – Alina C Fisher, Quarantine Quiz (Part 1?) My dear friend is a Master Gardener there and I had a small discussion with her as to Yucca as she was driving back from D.C. The yucca moth pollinates the plant and lays its eggs inside the plant. The interdependent relationships between the yucca moth and the yucca plant and the fig wasp and the fig tree typify exclusive mutualism. Thank you Yucca Moth for keeping your species and the yucca alive…. Hi Chris, Yucca is both a plant and a moth. | The Prairie Ecologist. When a female is ready to lay eggs, she first goes to a yucca flower to collect pollen. Male and female adults emerge when the yucca plant begins to bloom. Typically, there are more seeds than the larvae in a particular flower can eat (since the plant aborts flowers that are too heavily laden with eggs). It is a balanced relationship – the moth pollinates the plant and in exchange the plant provides food for the moth. Commensalism describes a symbiotic interaction in which one party benefits and the other is unaffected. Most plants and animals follow the same pattern, in which there is most biodiversity towards the tropics, and less towards the poles. When the eggs hatch, the larvae feed on yucca seeds within the fruit. Yucca (Yucca glauca), the state flower of New Mexico, illustrates an intimate relationship between a specialized pollinator and its equally specialized flower.The plant and the insect co-evolved; that is, they developed in intimate connection with each other.This is called an obligate mutualism in which if one were to disappear, the other would follow the same path. […], […] Using a comprehensive checklist of bee distribution and almost 6 million public bee records, an international team of researchers pioneered an insight into global patterns of bee diversity. What came first? Great article.

Pingback: The Connections Between Yucca Moths, Fledgling Robins, Teachers, and Learners – The Practical Psychosomaticist, Pingback: Photo of the Week – June 17, 2016 | The Prairie Ecologist, hi am from India nice to read this wonderful article :). Just as the honeybee and the flowers it pollinates need each other, so do the yucca and the yucca moth. Can the Yucca survive here and would it attract the moth to it? Fascinating!! Each species of yucca has a moth partner, a species of Tegeticula or Parategeticula moth. | The Prairie Ecologist. Yucca moths are also found in the southeastern portion of the U.S. and the West Indies, where just one species of yucca plant is known … A conservation story – Alina C Fisher, How and when yucca plant pollinated by moth, Pingback: Quarantine Quiz (Part 1?) I’d noticed the moths on the yucca and assumed they were specialists but had no clue they were responsible for the reproductive success of these grand plants. Music done by: Miley Cyrus "Wrecking Ball (instrumental)" Bangerz. It sounds too good to be true; two species helping each other survive for millions of years – each getting as much as they give. I would have never put together that they pupate into the only insect capable of pollinating said ‘host’. Fascinating. Many species of yucca plant can be pollinated by only one species of yucca moth, while those yucca moths use the yucca flowers as a safe space to lay their eggs. Sounds like romantic tale,the Yucca Plant has alot of fascinating aspects, the yucca known as actual meal among latin population it been substituted for potatoes,soups and even other meals, i think there sould be more information and i am doing a class project. Here’s why it matters – https://bhartiyanews24x7.com, This new project maps bees around the world. Active pollination among prodoxids has evolved only once, in the yucca … I wonder how long it would take for or other of the species to adapt if one did become scarce? They have been blooming & forming seeds for several years. In areas where bees are less abundant, you see a rise in alternative pollinators such as wasps, cockroaches or moths. The article is pretty informative for people who know little to nothing about the two species and thier symbiosis. ME? I recently had to write a haiku with “yucca” leaves as the prompt and this post has taught me so much…how nature works is fascinating! She may then return to the ovary of the same flower to lay more eggs or fly to another flower.  Either way, before she leaves the flower, she marks it with a pheromone (a chemical other moths can sense).  The scent marker will tell later visitors that they’re not the first to reach the flower, and they will either lay fewer eggs than the first moth, or none at all, depending upon how many moths have left their scent already. Acknowledgments: Thank you to Mary Ann Feist for help with this post. Pingback: Lessons From the Flowers: Living in Harmony with Symbiotic Plants | echelonflorist, Pingback: A Prairie Ecologist Holiday Reading List | The Prairie Ecologist. These plants are pollinated exclusively by the yucca moth, a moth which has evolved to use yucca plants to raise its young.Yuccas cannot be pollinated by other pollinators, forcing gardeners to pollinate by hand if they live in regions where the yucca moth cannot be found, and the yucca moth cannot … OK our science followed that since there were no outside burrowing holes, and the fact that they almost immediately died in sunlight and or oxygen they hadn’t seen much of the outside world. wow im only 12 and i found that very amazing. Change ). yucca moth family, Prodoxidae, shows that pollination has evolved at least three times from separate moth behaviors. If you’re interested in a much more detailed review of yucca moths, you might like this article by Olle Pellmyr. […] Using a comprehensive checklist of bee distribution and almost 6 million public bee records, an international team of researchers pioneered an insight into global patterns of bee diversity.

Please note that all comments are moderated and may take some time to appear. and the yucca moth (Tegeticula spp.) Do Yucca around Amarillo Texas need these same Moths? Unlike most moth species, yucca moths have two short tentacles near their mouth that they use to scrape pollen from the anthers of the flower. For more than 40 million years there has been a relationship between yucca plants and yucca moths. In all nature there are few cases of such obvious interdependence as exists between the Yucca plant and the Pronuba moth. The females actively collect pollen from one plant an… […], https://en.wikipedia.org/wiki/List_of_symbiotic_relationships, This new project maps bees around the world. The two species are involved in a … This mutually beneficial relationship probably started as a relationship of … Here’s why it matters – Warta Saya, This new project maps bees around the world. It is most amazing. My gut tells me it’s not a geographic thing, but a species thing. So many from cities move here and try making this habitat like the ones they left behind and have no idea how many creatures they are destroying or eraticating by their own selfish and ignorant behaviors. The Yucca Moth and the Soapweed plant have an interesting relationship that is necessary to both of them. Most yucca moths have white wings to blend in with the creamy blossoms of the yucca plants they pollinate. The Yucca plant reproduces through a symbiotic relationship with moths of the genus Tegeticula, that pollinates the yucca and survives on its nectar. This site uses Akismet to reduce spam. Since the larva develops into a moth that pollinates the yucca plant, the relationship is clearly beneficial to both partners. Interdependent relationships between communities of organisms exemplify the more general mutualism; these include, for instance: Insects, hummingbirds and even bats may depend on v… I had no clue that their was such thing as a yucca moth. Read more of Chris Helzer’s writings at The Prairie Ecologist blog, where this post originally appeared.Â. I’m pretty sure there is a yucca species native to Indiana, but I’m not 100%. When she arrives at the second yucca flower, usually one that has very recently opened, she goes straight to the bottom to find the ovary. An example is dung beetles, which live off the dung produced by other animals. Once the eggs are laid, she scrapes a small amount of pollen from her sticky ball with her tentacles, walks to the stigma of the flower, and packs the pollen into tiny depressions within the style. So each species depends upon each other for survival, and both benefit from the relationship. I had no idea anout the yucca moth in relation to the yucca. If you’re thinking of something for your yard/garden, I think you’d want to use the native species so that the host moth species would have chance of finding it (it’d be in the “neighborhood” already). The Sonoran Desert region is home to approximately ten species of yucca plant, and where there are yucca plants, there are yucca moths. This sort of relationship is called symbiosis. "The yucca is a bright and popular desert flower which seems tough and independent, sending up flowers of white lilies from a cluster of sharp leaves like wicked swords pointing out in all directions. If you’re interested in a much more detailed review of yucca moths, you might like this article by Olle Pellmyr. The yucca moth (Tegeticulla yuccasella) on soapweed yucca at The Nature Conservancy's Niobrara Valley Preserve in north-central Nebraska. In areas where bees are less abundant, you see a rise in alternative pollinators such as wasps, cockroaches or moths. On the other hand, if you just want something pretty, the yucca would still flower without the moth, it just wouldn’t make seed. Yucca plants are members of the lily family. She then flies off to another yucca flower. Thanks for introducing me to Berry Go Round! I interneted up. When a female is ready to lay eggs, she first goes to a yucca flower to collect pollen.  Unlike most moth species, yucca moths have two short tentacles near their mouth that they use to scrape pollen from the anthers of the flower.  As she collects the sticky pollen, the yucca moth packs it into a ball and sticks it under her head.  She then flies off to another yucca flower. As far as anyone knows, and it’s been studied since the 1870’s, no other species besides the moth pollinates yucca flowers.  Similarly, yucca moth larvae don’t feed on anything other than yucca seeds.  So each species depends upon each other for survival, and both benefit from the relationship. In fact, their symbiotic relationship is so specialized that many species of yucca plant can only be pollinated by a single species of yucca moth. Without the Yucca the moth would probably die and without the moth the Yucca would not naturally produce seed. Otherwise, pollination might be unlikely. Here’s why it matters - ThePrint | Philanthropy Media Network, This new project maps bees around the world. We live in england and have various flowering yucas in garden. Many species of yucca. 2013 Dr. Luke. I think it would be a nice part of that round-up of great plant posts. However, one of the most wonderful symbiotic relationships is between the Yucca tree and the Yucca moth. What an elegant relationship – thanks for sharing Chris, great photos. Excellent. The yucca (Yucca spp.) The relationship between yucca moths and yucca plants is an example of obligate mutualism. Most plants and animals follow the same pattern, in which there is most biodiversity towards the tropics, and less towards the poles. this is a great nature website. Yucca seeds provide the only food for the yucca moth larvae, so they need the plant to survive. Change ), You are commenting using your Google account.

I’m sure I will visit in the future for science research, Good thing I found this for my homework research, since the plants are abort they are to heavily to lay eggs. I visited your blog because of Ted MacRae’s recommendation. Opinions expressed on Cool Green Science and in any corresponding comments are the personal opinions of the original authors and do not necessarily reflect the views of The Nature Conservancy. The yucca moth uses the plant to safely lay its eggs, while the yucca is pollinated by the yucca moth. Change ), You are commenting using your Twitter account. Next year’s generation of moths won’t simply emerge when the weather becomes warm enough, they time their emergence with the blooming of the yucca plant so they can start this amazing cycle all over again. The symbiotic relationship between the insect and the plant is remarkable because the moth does not take advantage of the plant in ways other insects might. When the eggs hatch, the larvae feed on yucca seeds within the fruit.  Typically, there are more seeds than the larvae in a particular flower can eat (since the plant aborts flowers that are too heavily laden with eggs).  When the larvae finish eating, they burrow out of the fruit – usually during rain events, interestingly – and burrow down into the ground to make their cocoon and wait until the next spring when the whole process plays out again. Pingback: Why I Care About Prairies and You Should Too | The Prairie Ecologist. She did however say there’s someone locally you may want to talk to on the matter. The moth’s larvae depend on the seeds of the yucca plant for food, and the yucca plant can only be pollinated by the yucca moth. The Yucca Moth lives in the southwestern United States, Mexico, and the West Indes. Yucca – Air Cleaning Plant. ( Log Out /  One species of yucca moth, Tegeticula intermedia, betrays this obligate mutualism by not pollinating the yucca while still laying its eggs on the host plant, cheating the yucca out of any benefits from this relationship. The female yuccas fined a yucca plant and scrape off some pollin and then she will find another yucca plant and open it up and lay her eggs, and the pollin she takes can only be smelt by other yucca moths witch will tell them to either to lay fewer eggs or no eggs. Here's why it matters - ThePrint | Philanthropy Media Network. They are so interdependent that one cannot live without the other. Conforms to its yucca plant species host's range (which may vary from region to region). So, logic would presume that they had never left that cavity and were in fact formed in there. ABSTRACT: The relationship between yucca moths and yucca plants is an example of obligate mutualism. The best time to view moths in yuccas is just after sunset. The Yucca moths and the yucca plant help eachother out because only the yucca moth can polinate the yucca plant. the yucca plant–yucca moth relationship as a remarkable example of Darwinian evolu-tion; and, as the decades passed, Riley’s name and this storied case of plant–insect mutual-ism became conjoined. Thank you for this post, it filled in gaps. The word "mutualism" speaks to organisms or systems that have evolved mutually beneficial or complementary relationships, which may be highly exclusive or more generalized. Thank you! I’m just glad there are species that can and do c i continue the process of keeping live cycles going to enjoy what those relationships bring to those like myself who just enjoy being. George Engelmann in St. Louis made some first observations in 1892 (Engelmann, 1872). It’s a particularly important one because neither the yucca or the moth can survive without the other. This helps moderate the number of larva that hatch within each flower, and prevents the plant from aborting the flower altogether, which it will do if too many eggs are laid. At this point everyone kinda went back to their coffee/tea and it fell from mind. One such relationship is that between the yucca plant and the yucca moth.
