Monarchs and Milkweed

I am reading a fascinating book by Anurag Agrawal, an American professor at Cornell University of ecology, evolutionary biology, and entomology, called Monarchs and Milkweed: A Migrating Butterfly, a Poisonous Plant, and Their Remarkable Story of Coevolution. In it he describes the unique relationship between monarchs and milkweeds.

Monarchs and Milkweed: A Migrating Butterfly, a Poisonous Plant, and Their Remarkable Story of Coevolution by Anurag Agrawal. Click here to purchase book.

Monarchs need milkweed to survive since it is the only plant they use to feed their young. Without milkweed, there would be no monarchs. Fortunately, in North America alone, there are 100 different species of milkweed on which female monarchs seek to lay their eggs.

Milkweeds get their common name from the milky color of its sap. The sap contains toxins, called cardenolides, which the monarch has adapted to be able to ingest. These toxins serve to protect both the plants and the monarchs from predators. Milkweed provides protection for the monarch larvae as well as the adult butterflies. But the milkweed plants can also be toxic to the caterpillars so they have developed strategies to benefit from the alkaloids in the latex sap to prevent from being killed by those same toxins.

The latex sap of milkweed contains cardiac glycosides, among a variety of other toxic chemicals.

The newly hatched tiny caterpillar must face the challenge of the milkweed latex as it begins its first meal. A first instar caterpillar is so tiny this sticky substance can easily immobilize it if it isn’t careful. Typically the newbie caterpillars chew a small circle and then are able to eat the center portion. This behavior is called “trenching.” By doing so, the caterpillar effectively drains the latex from that small area of the leaf, and makes itself a safe meal. The method isn’t foolproof, however, and a good number of early instar monarchs become mired in latex and die. According to some research, as many as 30% of first instar caterpillars do not survive. (Source : It’s the first bites that count: Survival of first-instar monarchs on milkweeds by Myron P. Zalucki.)

After hatching, the larva eats its eggshell (chorion). It then eats clusters of fine hairs on the bottom of the milkweed leaf before starting in on the leaf itself. It feeds in a circular motion, often leaving a characteristic, arc-shaped hole in the leaf.

Fourth and fifth instar caterpillars larvae deactivate latex before eating leaves by chewing a shallow notch in the petiole (the stalk which attaches the leaf blade to the stem) of the leaf they are eating, which causes the leaf to fall into a vertical position. After the leaf hangs down, the caterpillar will flip around to eat the leaf.

The sticky latex sap in milkweed can make it difficult for the Monarch caterpillar to feed. This fifth instar caterpillar overcomes the obstacle by cutting the petiole of the leaf to halt the flow of sap, thus making the leaf easier to eat and preventing from consuming too much of the toxic sap.

Monarch larvae consume so much milkweed they increase their body mass by as much as 2,000 times or more during the larval stage.

One Monarch caterpillar will consume about 7-8 leaves of Common Milkweed (Asclepias syriaca). (Photo by Holli Hearn of Beautiful Monarch. Used with permission.)

To help monarch butterflies to survive and to thrive we need to plant more milkweed. You can never have enough milkweed when you are feeding hungry monarch caterpillars!

 

Top Three Trees for Butterflies

When planning a butterfly garden one typically thinks of planting flowers. But did you know that trees are some of the best plants for attracting butterflies?

Three common species of trees that support dozens of butterfly species and hundreds of moth species include oaks, willows, and chokecherries. Xerces Society’s Gardening for Butterflies calls these three trees “Keystone Trees” because attract multiple species of butterflies.

Oaks (Quercus spp.) support many different species of butterflies including the myriad hairstreak and duskywing species as well as the California Sister (Adelpha californica) and the Arizona Sister (Adelpha eulalia). Oaks also support the Imperial moth (Eacles imperiali), the Polyphemus moth (Antheraea polyphemus) and the Rosy Maple moth (Dryocampa rubicunda) in addition to others.

A Mourning Cloak (Nymphalis antiopa) is sipping on the sap of an oak tree.

There is such an incredible diversity of oak species that exist across the entire North American continent, many of which are small shrubs that can be used to add to your landscape. Some examples are the California Shrub Oak (Quercus berberidifolia), the Gambel Oak (Quercus gambelii) found in the Southwestern deserts into the Great Plains, the Turkey Oak (Quercus laevis) of the Southeast and the Scrub Oak (Quercus ilicifolia) of southeastern Canada and northeastern United States.

The Chokecherry (Prunus virginiana) is another tree that is distributed throughout much of the United States and southern Canada and is quite adaptable to various soil types and planting conditions. Chokecherry attracts widespread species of butterflies, both as a host plant for caterpillars and as a source of nectar for butterflies. Among the butterflies that use the Chokecherry as a host plant are the Lorquin Admira(Limenitis lorquini), the Tiger Swallowtail (Papilio glaucus), the Two-tailed Swallowtail (Papilio multicaudata), the Spring Azure (Celastrina ladon) and the Coral Hairstreak (Satyrium titus).

Chokecherry blossoms in spring are a good place to look for butterflies in search of nectar, as is this Juniper Hairstreak (Callophrys gryneus). NPS photo by Sally King.

Various willows (Salix spp.) are host plants for the Viceroy (Limenitis archippus), Mourning Cloak (Nymphalis antiopa), Red-spotted Purple (Limenitis arthemis astyanax), Tiger Swallowtail (Papilio glaucus), Mourning Cloak (Nymphalis antiopa), and the Lorquin’s Admiral (Limenitis lorquini). Willows are found in every part of the United States and Canada, with locally-appropriate native species available for any butterfly garden. These awesome trees are fast-growing and will tolerate many soil types. They come in a variety of sizes and shapes. Most willows do well in full sun and moist environments.

 

There are many different trees that attract butterflies, both as a source of nectar and as a host plant for caterpillars.  (Click here to see a list of host trees.) Trees also provide butterflies protection during bad weather as well as a place for them to perch during the day and to roost during the night.

Female Eastern Tiger Swallowtail (Papilio glaucus) is attracted to the sweet blooms of the American Plum (Prunus americana).

Remember, you will only attract butterflies that are native to your area. Find out what native tree species grow best for your region. The best place to start is a native plant nursery.

My Favorite Children’s Butterfly Books

So many wonderful books have been written for youngsters. Here are some of my favorites.

The Very Hungry Caterpillar
by Eric Carle

Of course, my all-time favorite children’s book is Eric Carle’s masterpiece. What a classic! This is a fun book to read, but it is not the best book to teach children about butterflies. After all, caterpillars do not eat oranges, or apples, or chocolate cake. Neither do caterpillars make cocoons. But it will delight children and  start them on their journey to learn more about butterflies.

The Language of Butterflies: How Thieves, Hoarders, Scientists, and Other Obsessives Unlocked the Secrets of the World’s Favorite Insect
by Wendy Williams

Once I started reading this book I could not put it down!  Williams will mesmerize and delight you with fascinating details about butterflies and the people who pursue them.

“Combining humor and poetry, Wendy Williams explores both butterflies and the people who love them…Humorist and poet though she may be, you don’t need to read Williams’ author bio to know she’s really a journalist, because she has a clear, logical style and a reporter’s instinct for telling stories through the people. One of the pleasures of the book is how gracefully Williams shifts between mini-profiles of pioneering butterfly fans and experts, the majority of whom are female or children or both…A charming, even suspenseful tale.”
