The interaction between monarch butterflies (Danaus plexippus) is to explore the root behind declining eastern monarch populations in relations to milkweed when laying their eggs onto milkweed leaves and aims for the. My students need seeds and supplies for growing a butterfly garden at school to learn about ecosystems and the relationships of organisms. These students. “The goal is for these 'monarch hotspots' to help amplify the seed available Monarch butterflies and milkweed have a symbiotic relationship.
Roy Lukes: The Fascinating Relationship Between Monarch Butterflies and Milkweed Plants
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.Monarchs & Milkweed - Yosemite Nature Notes - Episode 24
Illinois has 17, Arizona 26, and Mexico boasts of 59 species. Quite a few of these are eaten by the Monarch larvae. Strangely these fibers helped to save quite a few lives during World War II. The whisper-light fibers were used as a substitute for the unavailable kapok in the manufacture of life jackets.
Millions of pounds of pods were collected by Midwestern school children getting 25 cents per full burlap sack. I was one of those students and, believe me, I had no idea before beginning the project how many pods would be needed to fill one sack! Being hollow with natural waxy waterproofing on the outside, the silky fibers served as well in life jackets as they did in the pillows and cushions of many early pioneers.

Judging by the great success of the perennial milkweeds, having extremely durable, large, rope-like roots, they will be around for a long time to come, the leaves feeding the larvae of the Monarchs and the nectar of the flowers nourishing the adult butterflies. The last Monarch butterfly to leave the county will signal an official end to my summer.
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. Unfortunately, there are no substitutes for where monarchs can lay their eggs. Swamp milkweed in Altona Forest damp growing conditions Monarch on common milkweed dry growing conditions Milkweed is a broad-leafed native plant that is used by monarchs as their only nursery.
Monarchs lay eggs on the undersides of the leaves and their larvae become striped caterpillars and feed on the leaves as they develop. Without the milkweed, the caterpillars would die — but Ontario put milkweed on the noxious weeds list which forced its eradication.

The monarch caterpillars are not affected by the mildly toxic nature of this plant and become toxic themselves which makes them less attractive prey creating their defense mechanism. Monarchs feed and breed in Ontario summers.
Come colder weather, they make that astounding migration south.
