Actually, no. Monarch caterpillars do only eat plants in the Milkweed family ( Asclepias spp), so if we want to help them out in our wildlife gardens, we still need to add these plants to our gardens. Monarch caterpillars do not feed on tomato plants, despite what may seem like circumstantial evidence to the contrary.
Do monarch caterpillars eat butterfly weed?
Butterfly weed (Asclepias tuberosa) is a showy, bright orange perennial that gardeners usually prefer for their flower beds. But don't limit yourself to these two common species; there are dozens of milkweed varieties to plant, and monarch caterpillars will munch them all.
Do caterpillars eat milkweed leaves?
Milkweed leaves are covered in tiny hairs (called trichomes) that caterpillars don't like to chew. Some species of milkweed (like Asclepias tuberosa) are hairier than others, and studies have shown that monarch caterpillars will avoid the fuzzier milkweeds if given a choice.
How do you plant milkweed for monarch caterpillars?
Rough leaves for monarch caterpillars, not typically a preferred host plant for monarch females laying eggs versatile milkweed can be grown in gardens, meadows, and wildflower fields Prone to leaf spot fungus, rusts, and other milkweed diseases Sow directly in fall – November is a good option for most regions
Do monarch caterpillars suffer from cardiac glycosides?
Contrary to the story often told about monarchs and milkweed, the evidence suggests that monarch caterpillars can and do suffer the effects of consuming cardiac glycosides. Different species of milkweeds, or even different individual plants within a species, can vary significantly in their cardenolide levels.

Will monarch caterpillars eat Asclepias?
According to Rick Hellmich, an entomologist with the ARS Corn Insects and Crop Genetics Research Unit in Ames, Iowa, milkweed plants, primarily from the genus Asclepias, are the only food source of the monarch's distinctively striped larvae (caterpillars).
Which milkweed is best for monarch caterpillars?

Will milkweed leaves grow back after caterpillars?
It takes only a few caterpillars to defoliate an entire plant in a couple of weeks, but sure enough, the milkweed comes back every time.
Can I move monarch caterpillars to another milkweed plant?
The answers are yes, you may relocate the creatures once they make their chrysalis, and no, the caterpillars do not need to chrysalis on milkweed. In fact, Monarch and other chrysalises often are found as far as 30 feet from the hostplant where they ate their last meal.
What happens when monarch caterpillars run out of milkweed?
IT WILL MIGRATE. Tropical Milkweed (the kind we sold) regenerates leaves in about 2-3 weeks. This will give the NEXT A MOST IMPORTANT GENERATION fresh, clean, healthy leaves. Stripped plants will also give you a chance to CLEAN UP YOUR PLANTS and destroy aphids and milkweed beetles.
Should I let caterpillars eat my milkweed?
They do not contain the nutrients necessary for their survival. We recommend feeding vegetables to caterpillars only in emergencies and only in their last instar. Remember, when possible, always freeze milkweed leaves every year just in case you or a friend will need them.
What is the best plant for monarch butterflies?
milkweedWhile nectar plants are important, milkweed is an essential component of the monarch's spring resources. The relationship between the monarch butterfly and its host plant, native milkweed, is well known. Adult monarchs sip nectar from milkweed, and lay their eggs among its leaves.
Do monarch caterpillars only eat milkweed?
Monarchs Need Milkweed Monarch caterpillars ONLY eat milkweed. In fact, the monarch butterfly is also known as the “milkweed butterfly.” The milkweed plant provides all the nourishment the monarch needs to transform the Monarch caterpillar into the adult butterfly.
Do ladybugs eat monarch caterpillars?
To Milkweed, a Monarch Caterpillar is a Pest Those pests tear up our food plants and pretty flowers. But those ladybugs don't know that we planted some of those flowers so that insects would eat them. It was quite a surprise. Ladybugs kill monarch caterpillars.
Will monarch caterpillars eat tropical milkweed?
In addition to the concerns over OE and disruption of migration behavior, emerging research suggests that tropical milkweed may actually become toxic to monarch caterpillars when the plants are exposed to the warmer temperatures associated with climate change.
What is the best plant for monarch butterflies?
milkweedWhile nectar plants are important, milkweed is an essential component of the monarch's spring resources. The relationship between the monarch butterfly and its host plant, native milkweed, is well known. Adult monarchs sip nectar from milkweed, and lay their eggs among its leaves.
What else can I feed my monarch caterpillars?
Most enthusiasts have found most success with butternut squash as a substitute for milkweed leaves. Some of the other vegetables that have successfully been fed to Monarch caterpillars in the last instar (last few days) are cucumber, zucchini, and pumpkin.
How much milkweed does a monarch caterpillar eat?
Commercial butterfly breeders tell me that each Monarch caterpillar can easily defoliate an entire one-gallon milkweed plant–consuming 175 – 200 leaves per caterpillar–before eclosing to the chrysalis stage.
What Do Monarch Caterpillars Eat?
Monarch caterpillars eat the leaves of milkweed plant s, which belong to the family Asclepiadaceae. Monarchs are specialist feeders, meaning they will only eat a specific kind of plant (milkweeds), and cannot survive without it.
How do monarch butterflies defend themselves against predators?
Monarch butterflies gain an important defense against predators by feeding on milkweed as caterpillars. Milkweed plants contain toxic steroids, known as cardenolides, which are bitter-tasting. Through metamorphosis, the monarchs store the cardenolides and emerge as adults with the steroids still in their bodies.
What is a butterfly's mouth part?
Butterfly mouthparts are made for drinking nectar. If you look at a monarch butterfly's head, you will see its proboscis, a long "straw," curled up below its mouth. When it lands on a flower, it can unfurl the proboscis, stick it down into the flower, and suck up the sweet fluid.
Where does milkweed grow?
Common milkweed ( Asclepias syriaca) often grows along roadsides and in fields, where mowing practices may cut down the milkweed just as the caterpillars are feeding. Butterfly weed ( Asclepias tuberosa) is a showy, bright orange perennial that gardeners usually prefer for their flower beds.
Can caterpillars eat monarchs?
The caterpillars can tolerate the toxins, but their predators find the taste and effect more than unpleasant. Birds that attempt to eat monarchs will often regurgitate, and quickly learn that those orange and black butterflies don't make a good meal.
Do monarch butterflies drink nectar?
Monarch Butterflies Drink Nectar from a Variety of Flowers. If you're planting a garden for monarch butterflies, try to provide a variety of flowers that bloom throughout the months when monarchs visit your area. Fall flowers are particularly important, as migrating monarchs need plenty of energy to make the long journey south.
What pollinators do milkweed attract?
(If you know of other pollinators Asclepias tuberosa attracts, please share your sightings below.)
Can tuberosa be temperamental?
Since tuberosa can be temperamental about growing conditions, try planting in a couple different spots to see where it grows best.
Do monarch caterpillars have rough leaves?

Do leaves contain milky sap?
Leaves don’t contain milky sap like other species
What do monarch caterpillars eat?
Here in the St.Louis area, Monarch caterpillars are regularly found feeding on what is commonly called Honeyvine milkweed, I am in my second year of raising ones found in my garden on this plant. Despite its name, Honeyvine is not actually in the milkweed family (Asclepias), it is in the Apocynacea family. It looks similar to and often grows in conjunction with bindweed, so the post about caterpillars on bindweed may have actually been Honeyvine.
What happens when a monarch caterpillar enters the chrysalis stage?
What happens is this: when a Monarch caterpillar is ready to enter the chrysalis stage of its life cycle, it will leave the milkweed plants that it has been feeding on and travel (often quite a distance) to a place where it feels safe from birds and other predators.
What do black swallowtails eat?
I think some people might be mistaking the black swallowtail caterpillar for the monarch caterpillar. Black swallowtails eat parsley, fennel, and dill. I have seen plenty of black swallowtails on those herbs but never a monarch.
What butterfly caterpillar is similar to Monarch?
I think it would help this discussion topic if you posted a picture of the Black Swallowtail butterfly caterpillar with the article. The markings are similar enough that some people could be mistaking the Black Swallowtail caterpillar for the Monarch caterpillar.
Why should we plant milkweed in our ecosystem?
I’ve been telling you that we can help Monarch butterflies in our Ecosystem Gardens by planting more milkweed because that is the only plant that Monarch will lay their eggs on.
What caterpillar ate my starflower cactus?
The egg must have been laid on it. It has now turned into a beautiful green chrysalis with a gold trim and gold dots.
What position does a caterpillar take when it finds a safe place?
Once the caterpillar finds a safe place, it will assume the “J” position and begin the process of transforming into the chrysalis phase.
What is the best plant to deter deer?
Hairy leaves: Gardeners know that the best plants to deter deer are those with fuzzy leaves. The same principle holds true for any herbivore, really, because who wants a hairy salad? Milkweed leaves are covered in tiny hairs (called trichomes) that caterpillars don't like to chew. Some species of milkweed (like Asclepias tuberosa) are hairier than others, and studies have shown that monarch caterpillars will avoid the fuzzier milkweeds if given a choice.
Why is milkweed called milkweed?
In fact, this is why Asclepias plants are nicknamed milkweed – they seem to weep milk from their leaves and stems. This latex is pressurized and laden with cardenolides, so any break in the plant's capillary system results in an outflow of toxins. Latex is also rather gummy. Early instar caterpillars are particularly susceptible to the gooey sap that all but glues their mandibles shut.
How do caterpillars eat latex?
Next, the caterpillar must tackle the challenge of the latex. A first instar caterpillar is so tiny this sticky substance can easily immobilize it if it isn't careful. Perhaps you've noticed that the smallest caterpillars will chew a circle into the leaf first, and then eat the center of the ring ( see inset photo ). 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%). Older caterpillars may chew a notch into the leaf stem, causing the leaf to droop and allowing most of the latex to drain out. Once the milky sap stops flowing, the caterpillar consumes the leaf ( as in the photo above ).
What is the best food for monarch butterflies?
Debbie Hadley is a science educator with 25 years of experience who has written on science topics for over a decade. Most people know that monarch butterflies benefit from feeding on milkweed as caterpillars. Milkweed contains toxins, which makes the monarch butterfly unpalatable to most predators.
What are the chemicals in milkweed?
Cardenolides: The toxic chemicals found in milkweeds are actually steroids that impact the heart, called cardenolides (or cardiac glycosides). Cardiac steroids are often used medically to treat congenital heart failure and atrial fibrillation, but historically they've also been used as poisons, emetics, and diuretics.
Why do monarch butterflies use aposematic coloration?
The monarchs even use aposematic coloration to warn predators that they will be eating a toxic meal, should they choose to prey on the orange and black butterfly. But if milkweed is so toxic, why don't the monarchs get sick from eating milkweed? Monarch butterflies have evolved so they can tolerate the toxic milkweed.
Do milkweeds have cardenolides?
Different species of milkweeds, or even different individual plants within a species, can vary significantly in their cardenolide levels. Caterpillars feeding on milkweeds with high levels of cardenolides have lower survival rates.
How many milkweeds do monarch butterflies lay eggs in?
According to an ARS and Iowa State University study of nine milkweed species native to Iowa, female monarch butterflies laid eggs in all nine milkweeds, but the swamp and common milkweed averaged the highest number of eggs. (Peggy Greb, D4226-1)
What do monarch caterpillars eat?
Share. A monarch caterpillar feeds on common milkweed, Asclepias syriaca. Milkweed plants, primarily from the genus Asclepias, are the only food source of monarch caterpillars. (Peggy Greb, D4225-1) Not all milkweeds are created equal when it comes to species of the native flowering plants that monarch butterflies prefer most.
What is the only food source for monarchs?
According to Rick Hellmich, an entomologist with the ARS Corn Insects and Crop Genetics Research Unit in Ames, Iowa, milkweed plants, primarily from the genus Asclepias, are the only food source of the monarch’s distinctively striped larvae (caterpillars). Natural chemicals the caterpillars ingest from milkweed also protect them and the adult butterflies they’ll later become from predation.
Why are monarchs declining?
Over the past 2 decades, however, monarch numbers east of the Rockies have fallen by 80 to 90 percent. The decline is partly attributed to shrinking milkweed habitat, especially in the Midwest.
Where do monarch butterflies migrate?
Every year, monarch butterflies migrate to and from overwintering sites in mountain regions of Central Mexico.
Which flower has the most eggs?
Swamp milkweed (Asclepias incarnata) and common milkweed (A. syriaca) averaged the highest number of eggs.
When do monarch chrysalis come to Mexico?
They arrive at their summer breeding grounds—the Midwest—in late spring and increase their population size over two to three generations before returning to Mexico. A monarch chrysalis hangs from the leaf of common milkweed, Asclepias syriaca.
