Monarch Butterfly and Milkweed by Audrey Waters on Prezi
By: Doris Ames. The Monarch Butterfly (Danaus plexippus) is familiar to most Manitobans. . The exact nature of the relationship between the monarch butterfly and the milkweed is still unclear. It seems to be a type of mutualism. We know that. The fascinating and complex evolutionary relationship of the monarch butterfly and the milkweed plant. Monarch butterflies are one of nature's most. The lack of knowledge on the relationship between milkweed, monarchs, and Alonso thinks that this decrease is due to scale loss from the butterflies' wings.
The offspring will arrive in northeastern Wisconsin in late May to early June. From that point on you can expect a new generation about every four weeks.
NOCI Milkweed and Monarchs
The cooler the weather becomes the longer the process is. A minimum air temperature of 59 to 61 degrees Fahrenheit is critical for their flight. They cannot fly in air below this temperature. The warm sunny days of mid- to late-September will find thousands of Monarchs perhaps following the shoreline of Lake Michigan on their way to that secluded place in Mexico they have never seen. Try to figure that miracle out! An interesting thing happened one summer in mid-August while leading a field trip involving 20 people.
Ladies outnumbered the men four to one. During the course of the next several minutes that butterfly proceeded to land on the arm or hand of only the men.
You may draw your own conclusions! Moments later someone in the group discovered a lovely jade-green chrysalis of a Monarch at least 75 feet or more from the nearest milkweed plants.
That was quite a journey for that small caterpillar. While there are at least 12 different species of milkweeds in Wisconsin, by far the most abundant species consumed by the Monarch caterpillars is the Common Milkweed, native to the other Great Lakes states and Canada as well. Become a Contributor Examples of Commensalism for a Better Understanding of the Concept Commensalism being a type of symbiotic relationship between organisms, other types of symbiotic relationships include mutualism, in which both the organisms involved benefit from each other, and parasitism, where one of the organisms is benefited, while the other is harmed.
ScienceStruck Staff Last Updated: Mar 22, Many instances of commensalism are surrounded by controversies, as there is always a possibility that the commensal host is also being benefited or harmed in some or the other 'not-yet-known' ways.
However, here are some of the widely accepted examples of commensalism found in nature. Examples of Commensalism Cattle Egrets and Livestock One of the popular examples of commensalism is the relationship between cattle egrets and livestock. The cattle egret is a common species of heron that is found in most regions of the world, and is mostly seen moving along with herds of cattle. This bird moves about in the pastures, and follows livestock such as cattle and horses.
The cattle egret eats up the insects hiding under vegetation close to the grounds, which get stirred up when the cattle walk through them. Orchids Growing on Branches of Trees Orchids belong to a family of flowering plants that form a commensal relationship with the trees.
It is a well-known epiphytic plant that grows on the branches or trunks of other trees. Orchids are usually found in dense tropical forests.

They form their base of attachment on the branches of trees, and benefit by getting adequate sunlight and nutrition that flows down the branches. The orchids do not grow to a large size, and thus the host tree is not harmed in any way. Remora Fish and Sharks The remora, also called suckerfish, belongs to a family of ray-finned fish. It is a small fish growing up to a size of 1 to 3 feet. The remora forms a special relationship with sharks and other sea organisms like whales and turtles.
It has special suckers attached to its fins. It attaches itself to the bodies of sharks, and uses the shark for transportation as well as protection from its predators. Past the Great Lakes, through the Appalachian forests, and past the Texas coasts all the way to a few acres of Oyamel fir cloud forest in Mexico. Changes to global weather patterns have decimated populations in their wintering grounds — like the deep freeze of a couple years ago.

Still these few small areas of central Mexico are the only places they travel to. When you see a monarch arrive in your garden, stop and realize that it has taken generations to get here. They slowly began to make their way across the US and stopped to have another generation. If all goes well, the second or third generation will make it to your back yard.

Many starve if they cannot find sufficient wildflower nectar in farmlands to sustain them, and rainstorms, windstorms, and pesticides are often fatal to them. There is a symbiotic relationship between the native milkweed plants and the monarch. The monarch butterflies enjoy the nectar from the flowers and help pollinate the plants.Monarchs & Milkweed - Yosemite Nature Notes - Episode 24
Unfortunately, there are no substitutes for where monarchs can lay their eggs.
