Monarch Butterfly Chatbook – Milkweed


An important way to help the monarch butterfly is to first identify the host plant. Plant Identification has two names: Common and Latin. The birth of the monarch butterfly in the Chatbook frequently refers to common milkweed (Asclepias syriaca). The italicized Latin name first describes the Genus that is capitalized followed by the species in lower case. Native plants are perennial. Once planted they will start their own colony thus ensuring the future of the plant species.  

In spring, when milkweed is just emerging from the soil, the monarch returns to North America from Mexico. The butterflies will stop along the way in Texas where they will mate. Shortly after mating, the parents will die but not before the mother butterfly lays her eggs.  Butterflies with more than one host plant have a better chance of survival than a monarch with only one host plant. The female butterfly deposits her eggs on milkweed and it is the only plant that young caterpillars or larvae (LAR-VEE) eat.

Common milkweed grows in prairies, along roadsides, in agricultural areas and fields, at the edge of forests and even in one’s own backyard. Milkweed originates in the Americas meaning it is a native plant. There are approximately 100 species of milkweed in North America alone.  It is important to let milkweed grow for the monarch butterfly. Different generations of the monarch butterfly migrate to and from Mexico, North America and Canada each year, an estimated distance of 2,000 miles. Migrating north from Mexico, generations of female butterflies’ will need milkweed all along the migration trail. What is so special about milkweed?

Milkweed has several advantages. The plant has a long taproot which looks similar to a carrot taproot. Taproots can go deep into the earth to reach water; native plants do not need watering once they are established. Depth of plant roots is important in times of drought when there is little or no water. People around the world are starting to learn about Global Warming which can cause drought and severe storms.

Milkweed also contains cardiac glycoside a chemical that is toxic. Monarch caterpillars have the unique ability to eat the toxic leaves without any ill effect. Eating milkweed in its early life stage helps enable the adult butterfly to have a chemical defense against possible predators such as birds.  Often birds will throw up after eating a monarch. Captured bluejays were researched and videotaped as they ate milkweed and afterwards by Anu Uno Chellappau. On the other hand, my friend Anna Martineau Merritt has seen a bird eating a monarch without getting sick. Robert Pyle attests to this too. He watched as orioles ate monarchs at the Mexican Monarch Butterfly Sanctuary in El Rosario (55).

Sadly, I saw a monarch in my own garden that was less than 24 hours old. In the late afternoon it was resting peaceably on a bright pink zinnia flower and by early evening the new born butterfly had been attacked and killed by a predator. The wings were left behind but the body was gone. At times birds will eat the body which has nutritious fats. Perhaps a bird ate the body and not the wings where most of the toxins are stored. The butterfly also has bright colors that warn predators it is not good to eat.

Stop illegal deforestation at Monarch Butterfly Sanctuaries

I thought this pupa was a jewel when I first saw it in the garden


Background (Preamble):


In Mexico there is illegal logging of Oyamel fir trees within the Monarch Butterfly Habitat. In 2010 according to Monarch Watch over 50 percent of the monarchs died due to mudslides, freezing rains and floods within and around the sanctuaries.

We the undersigned promise not to use pesticides or herbicides in gardening. We agree not to plant monoculture crops.

We promise to plant a variety of native crops and plants for pollinators and insect control. We promise to plant milkweed for the monarch butterfly to establish the next generation of butterflies.
