 If you have read our Blog on Common Monarch Ailments, you will find that there are many diseases, parasites and infections that can infect Monarch caterpillars. It is a common problem for many Monarch rearers but there are ways to prevent this from happening and also prevent it from spreading. Here is how to prevent disease from spreading once you suspect your Monarch may be infected. What You Can Do1. Isolate Your Caterpillar
If there is a chance of infection, move your caterpillar or chrysalis to an area by itself where it cannot infect other caterpillars. Use a milkweed leaf, gloves or brush to avoid touching the caterpillar directly. If you think you may have touched it, wash your hands afterwards. TIP: If the caterpillar has reached chrysalis stage and something seems off, you can use a piece of floss or thread to remove the silk pad from the cage and move it to another area. 2. Clean Cage Once you remove the potentially infected caterpillar, promptly disinfect the entire cage to prevent contamination to other caterpillars. To do this, remove the other cats and place them in a clean holding container until you are finished cleaning the cage. Also, replace old milkweed leaves with fresh leaves. To disinfect cage you can use a weak bleach solution (about 1 to 10 parts bleach to water) or a natural disinfect such as Meyer's Multi-surface Cleaner. Use a spray bottle or dunk cage in a large tub and let it sit for about 30 minutes. Rinse thoroughly with water afterwards and allow to DRY before adding any caterpillars back in. 3. Keep A Close Eye on Your Sick Caterpillar Check on the caterpillar every 4-6 hours to see if the case worsens. Keep the potentially dangerous Monarch separated until it reaches full metamorphosis to avoid spreading the ailment.

We wanted to share this inspiring story by one of our followers, John Perez, who has helped to create many Monarch educational opportunities within the Montebello Unified School District. We want to encourage all educators and teachers to participate in our Monarch School Program including those involved with 4-H, Scout troops, YMCA and other Community learning centers! |

Many teachers and educators have heard of his Monarch campaign and have asked to be included. Bell Gardens Elementary has created a full-scale garden with Milkweed plants and vegetables. A parent/ volunteer has also created an incubation station where eggs are kept safe until they reach adulthood and then released.
At Greenwood Elementary, one teacher and his classroom have created a Pollinator Garden and dispersed 100 Seed Packets.
On behalf of Save Our Monarchs, thank you to ALL of the Monarch educators and teachers!

So you've raised your caterpillars to total metamorphosis, now what?
1. Allow the newly emerged adult 3-4 hours to inflate and dry their wings. Do not touch them when their wings are still wet or it may damage them.
2. When the butterflies first emerge, they are quite lethargic and slow-moving for the first few hours. They may just walk onto your finger if you gently nudge their legs. Then, you can carry them outside and place them on a plant.
3. If your butterfly has had more than a few hours and is feeling a bit more active, you will have to hold them differently in order to minimize damage to their wings/scales.
4. Starting with your pointer and middle finger in a scissor-like position, gently hold all four wings as close to their body as possible. This way they will not be able to flap their wings and damage them. Then, carry them outside.
NOTE: Sometimes the weather does not allow you to release your Monarch right away. If is below freezing, raining, hailing, snowing or there are strong gusts of wind, it is best to keep your Monarchs safe inside until this passes. You can feed them fresh cut fruits and/or honey water while they are waiting out the storm.

 | In the wild, Monarch eggs and larvae have a very small chance of survival. In fact, studies show that 90% of Monarchs do not survive the egg and larva stages. |
Materials Needed
   | 1. Ventilated container You can now buy these enclosures on our website! You may also use aquariums, deli containers, clothing hampers but make sure they are clean and well-ventilated. 2. Paper towels or Newspapers This is for lining the cage and simplifying clean- 3. Monarch caterpillars or eggs These can be found outside on milkweed plants. Look carefully on the underside of leaves and on flower buds for eggs and larvae. 4. Milkweed This can be grown in your own backyard or bought from a nursery. If you choose to buy from a nursery, make sure you ask if it has been sprayed with any pesticides which can be fatal to monarch caterpillars. Often nurseries will spray all of their plants with pesticides so your best bet is to grow it yourself. Plan for at least one plant per caterpillar. |
5 Steps to Rearing Monarchs
Step 1: Find the eggs and/or caterpillars
 | The best way to do this is to visit milkweed plants daily that you know are already established and ,hopefully, already in your backyard! If you see a Monarch land on your milkweed plant, it is very likely they left an egg behind so check right away. Carefully look on the underside of the leaf, where they often lay eggs. 1st instar caterpillars and eggs are TINY so look very closely. |
Step 2: Bring them inside
 | Once you find a caterpillar or egg, cut off the entire leaf or branch that the egg or caterpillar is on, bring it inside and put it in a glass of water to keep the cutting fresh. Put the eggs or caterpillars in the ventilated container of your choice after lining with newspaper or a rubber mat (for easy clean-up). Eggs only take 4 days to hatch and caterpillars will form a chrysalis within 2 weeks. Caterpillars have a huge appetite and can eat 200X their weight in Milkweed! A single caterpillar can easily defoliate a milkweed planted in a 1 gallon container so plan accordingly. Provide fresh leaves daily or enclose the entire milkweed plant. Larvae will survive best and attain a large size if you keep the food fresh, the container clean, and the humidity low. |
Step 3: Clean the cage regularly
The caterpillars are eating constantly so they will generate a lot of frass (cute name for you know what). This frass should be collected every other day in order to keep the larvae healthy and prevent diseases from spreading. You can simply replace the bottom of the container with more paper towels or newspaper paper for easier clean-up. Just throw the frass into your compost bin to add nitrogen!
Step 4: Keep feeding the hungry caterpillars!
 | It's important to remember that as the caterpillars get bigger, so will their appetite so keep a close eye on them and make sure you are providing enough fresh Milkweed. After the caterpillar reaches it’s 5th instar (molting stage) it will climb to the top of the container and begin spinning it's silk pad. It will not need any food at this stage so your job is mostly done. |
Step 5: Release Your Butterfly Into the Wild
 | The chrysalis will turn clear before the adult butterfly emerges (fully metamorphosed). It is important not to touch them for at least 5 hours so their wings can dry. Keep an eye on the weather and do not release your Monarch if there is a storm on the horizon. You may need to move the butterfly into a larger container if this is the case such as an upside down laundry basket or a mesh cage |
Please note that even in captivity, Monarchs can develop diseases, parasites, bacterial infections and other illnesses. The best way to prevent this from happening is to keep a very clean cage that is kept dry and not humid. For a list of common monarch ailments click here.
Furthermore, we do not support large scale monarch breeding operations or the sale of monarch caterpillars. We DO support responsible rearing of monarchs, especially in an educational environment.
Monarch Life Cycle
Egg
Monarchs overwinter in Mexico and certain parts of Southern California. When they wake up from hibernation, they will intuitively head North and East to start laying eggs.
In March and April the eggs are laid on milkweed plants and it takes only 4 days for an egg to hatch!
According to Karen Oberhauser, Monarch biologist, captive monarch butterflies average about 700 eggs per female as opposed to 300-400 in the wild.
Monarch females usually lay a single egg on a milkweed plant on the bottom of leaf. So, when searching for eggs, don't forget to flip the leaf over! Eggs are very small and sometimes easy to miss!

Larval Stage (Caterpillar)
The larval stage last 2 weeks. Once the egg has hatched, a very small (and hungry) caterpillar emerges. During this time, the caterpillar will spend most of it's time eating so it will need fresh leaves everyday. As the caterpillar grows and becomes too large for its skin, it molts. The intervals between molts are called instars. Monarchs go through 5 instars. Click here if you'd like to learn more about differentiating the different instars.
Pupa (Chrysalis)
 The chrysalis is green with a golden diadem at first. |  The chrysalis turns clear within 24 hours of opening. |
Once the Monarch larvae has reached the final molting stage, they will hang upside down by their last pair of prolegs and create a chrysalis. They will spend between 1 and 2 weeks inside this chrysalis.
Adult Butterfly
Once adults, Monarchs will live another two to six weeks in the summer. However, the last generation of super Monarchs that complete the migration much longer, about six to nine months.

There are more than 20 butterflies and moths listed as endangered by the U.S. Fish and Wildlife Service!
The main reason for these butterflies being placed under the Endangered Species Act is mainly due to loss of habitat (agriculture, commercial, residential). However, other reasons include: poor land management practices, excessive use of pesticides and herbicides, and loss of the butterfly's host plant that is necessary for it's growth and development.
If faced with the risk of extinction, any species can be put under the protection of the Endangered Species Act (ESA). They are placed either as "threatened" and "endangered". To clarify those two terms: an “endangered” species is one that is in danger of extinction throughout all or a significant portion of its range. A “threatened” species is one that could become endangered in the near future.
The U.S. Fish and Wildlife Service received a petition to list the Monarch butterfly under the Endangered Species Act (ESA) on August 26, 2014. The status is currently under review and will be released by June 2019.
Note: These butterflies are all listed as "Endangered" under the Endangered Species Act. The list is not exhaustive and the complete list can be found on the USFWS ECOS site here.
Karner blue butterfly (Lycaeides melissa samuelis)
Federal Status: Endangered
Host plant: Wild lupine (Lupinus perennis)
Historical Range: Illinois, Indiana, Massachusetts, Michigan, Minnesota, New Hampshire, New York, Ohio, Pennsylvania, Wisconsin.
History and Description: The Karner blue butterfly was first described more than a century ago in Karner, New York. It is a small butterfly, with a wingspan of about one inch. The male's wings are distinctively marked with a silvery or dark blue color. The female is grayish brown, especially on the outer portions of the wings, to blue on the topside, with irregular bands of orange crescents inside the narrow black border. (ECOS- Environmental Conservation Online System)
While adult Karner blues feed on a variety of plants, wild lupine is the only known food plant for their larvae. Without wild lupine the cycle of life for this butterfly would be broken. Lupines are adapted to particular environmental conditions. The plants required by the larvae of the Karner blue, are found in savanna, barrens, and dune habitats which were once quite extensive. However, like many other places the habitats of the Karner blue have been subject to extensive development with a resulting decline in the butterfly. (USFWS Podcast Dave Harrelson)

Callippe silverspot butterfly (Speyeria callippe callippe)
Federal Status: Endangered
Host plant: Johnny-jump- up (Viola pedunculata)
Historical Range: California
History: "The callippe silverspot was historically found around the eastern, southern, and western sides of San Francisco Bay, but is now limited to just seven sites. It is found in native grassland and adjacent habitats, where females lay their eggs on the larval food plant, Johnny-jump-up. The causes of the callippe silverspot’s decline are fairly clear: The vast majority of potential butterfly habitat lies under the cities of San Francisco, Oakland, and Berkeley, and what open areas remain within this butterfly’s range are dominated by introduced plant species. Many of these areas are also grazed by cattle, mined, or subject to heavy recreational use." (Xerxes Society)

Saint Francis' Satyr (Neonympha mitchellii francisci)
Federal Status: Endangered
Host plant(s): Grasses, sedges, and rushes and are usually located in wet meadows
Range: North Carolina.
History: "The Saint Francis’ satyr occurs in the sandhills of Cumberland and Hoke counties, North Carolina, (a single metapopulation) and has a single record in Virginia. Soon after its discovery in the 1980s, it was believed that this butterfly had been collected to extinction, but happily it was rediscovered in 1992. Its habitat is wet meadows, previously likely created by fire or beaver activity, although now mainly maintained by human activity. Despite its protected status, it is still in demand by collectors".

San Bruno elfin butterfly (Callophrys mossii bayensis)
Federal Status: Endangered
Host Plant: Sedum spathulifolium. Montara Mountain colonies are suspected to use Montara manzanita (Arctostaphylos montaraensis) and California huckleberry (Vaccinium ovatum). (Xerxes Society)
Range: California.
History: Its habitat has been diminished by quarrying, off- road recreation, and urban development. Development pressures on the San Francisco peninsula continue to grow, and the major threats to the butterfly— increased urbanization in the area, and loss of habitat by road construction and rock and sand quarrying—reflect this. Grazing may have encouraged the growth of exotic plants in the area. In the early 1980s, a habitat conservation plan was developed to allow development on San Bruno Mountain while minimizing the adverse effects on the San Bruno elfin butterfly and other rare species in the area. This plan is currently being amended, which may result in further urban development. (Xerxes Society)

Schaus swallowtail (Heraclides aristodemus ponceanus)
Status: Endangered
Host plant(s): Torchwood and Wild lime
Range: Florida.
History: Listed on April 28th, 1976 as threatened, the Schaus swallowtail was the first butterfly to be protected under the Endangered Species Act, or ESA as the law is often referred to. This butterfly was originally described by William Schaus in 1911 from specimens collected in the south Miami area in 1898. The butterfly was originally distributed in southern Florida’s tropical hardwood hammocks from south Miami to Lower Matacumbe Key. Hardwood hammocks are a type of forest that is on ground that is slightly elevated above the surrounding landscape. These forests are essential for the survival of the butterfly. The ongoing loss of habitat and food plants was pushing the Schaus swallowtail even farther toward the brink of extinction. This resulted in the Fish and Wildlife Service reclassifying the butterfly to the more imperiled status of endangered in 1984. (Xerxes Society)

 | Milkweed seed bombs are fun and easy to make and a great way to create Monarch habitat. Seed bombs are also the perfect winter project to get kids interested in gardening and the environment! |
So, what is a seed bomb?
A seed bomb is a quarter sized ball made of clay, compost and seeds which is used to casually plant milkweed and other native plants. They are often used in guerrilla gardening.
How do seed bombs work?
Reseeding areas by the traditional method of broadcasting seeds poses several problems but seed bombs can remedy all those issues. For instance,
All of this adds up to increased germination rates and a self-sustaining system!
- The clay protects the seed from drying out in the sun
- The seed bombs are heavy enough to not be affected by wind or heavy rains
- The clay casing deters animals from eating them
- The shape of the ball conserves moisture
- The compost provide nutrients for the seeds
- As the seeds begin to germinate and grow, they provide shade for the next generation of seeds
All of this adds up to increased germination rates and a self-sustaining system!
STEP 1: Gather Your Ingredients
 |  |  |
STEP 2: Mix Compost, Clay and Water together
Start with 1 cup of compost and 1 cup of clay. Mix together in a bowl and add about 1/2 cup of water. The consistency should be just sticky enough to adhere the compost and clay together. You can add more or less water/soil to get this consistency.
Pro Tip: For me, 1 cup of both made 15 quarter-sized seed bombs. You can use this recipe to multiply it to make your desired amount of seed balls.
Pro Tip: For me, 1 cup of both made 15 quarter-sized seed bombs. You can use this recipe to multiply it to make your desired amount of seed balls.
Step 3: Roll into balls
Just like making cookies! Grab enough clay mixture to make about a 1 inch in diameter ball.
Step 4: Add Seeds
Use a tooth pick to poke holes in each ball. 15-20 seeds per seed bomb is about right for a 1 inch size ball.
 For some of the seeds bombs I also added a mix of wildflowers. To create a complete habitat for Monarchs you need both host and nectar plant-sources! | Save Our Monarchs has special offers on bulk seeds. Use promo code 'Seedbomb' for 10% off! 1/2 oz 1,500 seeds $25 = 100 bombs 1 oz 3,000 seeds $50 = 200 bombs 4 oz 12,000 seeds $75 = 800 bombs 16 oz 48,000 seeds $135 = 3200 bombs IMPORTANT NOTE: Germination rates will be greatly reduced if not planted correctly! Milkweed seeds can be very slow to germinate and does take some time and patience. For best results and to speed up the germination process, place the seeds in wet paper towels in a plastic bag in the refrigerator for 30 days prior to planting. |
Step 5: Reshape into a ball and allow to dry
Once you’ve added the seeds, roll the seed bombs in your hand to make sure seeds are tucked in nicely.
Lay seed bombs out on a newspaper or cardboard box and allow to dry for 24-48 hours or until hard. Avoid drying them on plastic to avoid mold.
After drying, you can also store the seed bombs in an airtight container in a cool, dry place until it’s time to plant. Mason jars or glass Tupperware work well for this!

How to plant your milkweed seed bombs
When: You can plant them now while there is still snow on the ground so that the milkweed balls will still cold-stratify before Spring arrives.
Pre-stratified seeds, can be planted in the Spring after the first frost has passed.
You can also plant in the Fall once there have been a few frosts and there is no chance the seeds will germinate before Spring.
How: Simply throw the seed bombs onto bare soil. With a little water, plenty of sunlight and compost, your seed bombs will germinate and become a beautiful haven for Monarch butterflies!

We all know that monarch larvae eat milkweed plants, but what about the other insects that share a food source with Monarchs?
The truth is, most of these insects serve a purpose within their respective ecosystems. The reason that many of them are black and orange like Monarchs is that they use the same defense mechanism called "aposematism" where their black and orange coloration warns predators of their toxic/bitter taste caused by cardiac glycosides which they acquire from milkweed.
Learn how to identify these insects and find out if they are harmful or harmless to Monarchs!
Red Milkweed Beetle (Tetraopes tetrophthalmus)
Native range: Their range matches the distribution of Common Milkweed (Asclepias syriaca), basically the Northeast quadrant of North America
Harmful to Monarch caterpillars/eggs? No. They are herbivores and only eat milkweed. They are harmless to monarch larvae and eggs so you can leave them on your milkweed plant if you have enough to go around.
Identification: Red/orange in color with oval spots all over body and un-ringed antennae.
Life Cycle: Eggs laid on stems near ground or just below surface; larvae bore into stems, overwinter in roots, and pupate in spring; adults emerge in early summer

Small Milkweed Bug (Lygaeus kalmii)
Native range: Throughout US and Southern Canada
Harmful to Monarch caterpillars/eggs? Sometimes. They are mostly herbaceous and will suck nectar from flowers and sometimes feed on milkweed seeds. However, they have been reported to be predators, especially in spring when milkweed seeds are scarce. They have been reported feeding on honey bees, monarch caterpillars and pupae, and dogbane beetles, among others (Root 1986). The best method to remove the bugs from your milkweed plant is to grab them and throw them into a bucket of soapy water.
Identification
They adult is black with a broad orange/red band on forewing, forming an "X" shape. Their head is black with a dull red spot on top. In eastern specimens, forewings are all black, but in western specimens they have large white spots. (Bugguide.net)
Life cycle
Eggs are laid on milkweed in spring. One or more generations per year. Adults overwinter.

Large Milkweed Bug (Oncopeltus fasciatus)
Native range: Throughout North America and from Central America through Mexico and the Caribbean to southern areas in Canada.
Harmful to Monarch caterpillars/eggs? No, they do not feed on Monarch larvae or eggs so they are harmless and play a role in the ecosystem. However, they do feed on the seeds, leaves and stems of milkweeds (Asclepias). Damage to the plants can deplete resources for Monarch caterpillars. Planting more milkweed will ensure that they both have enough to eat.
Identification: Adults are overall black and orange- with black band in the middle and two large black spots in front and back. Nymphs are bright orange and develop black spots late.
Life Cycle: Eggs are laid in milkweed seed pods or in crevices between pods. About 30 eggs are laid a day, and about 2,000 over a female's lifespan, which lasts about a month during the summer. One or more generations per year. They can't survive cold winters, so they migrate south in the fall. They overwinter in the southern Atlantic and Gulf coast states where they feed and breed and gradually migrate north again in the spring and summer. (bugguide.net)

Swamp Milkweed Leaf Beetle (Labidomera clivicollis)
Native range: Widespread in North America east of the Rocky Mountains, south to northern Mexico (Riley et al. 2003)
Harmful to Monarch caterpillars/eggs? Technically, no, because they are herbaceous. However they do feed on milkweeds, especially Swamp Milkweed (Asclepias incarnata), but also Common Milkweed (A. syriaca). To control populations from eating all of your milkweed, you can pick them off and put them in a soapy bucket of water.
Life Cycle: They often overwinter as adults among leaves such as mullein (Verbascum). Adults mate on or around milkweed. Eggs are cemented to the underside of leaves. Larvae feed on leaves, and drop to ground to pupate (National Audubon Society Field Guide to Insects and Spiders)
Note: Unlike the Monarch, larvae and adults of the milkweed leaf beetle are not thought to sequester cardiac glycosides from their milkweed host.

1. The surface of a Monarch's wing is covered with thousands of tiny, colorful scales. Loss of these scales is what causes Monarchs to lose their color!
Have you seen a tattered and faded Monarch? After flying for a long period of time, these scales will fall off and the Monarch's wings will appear faded or even clear. You can generally tell the age of a Monarch this way!
The tiny scales on the wings of Monarchs have been studied by biologists and aerospace engineers alike to better understand how they affect flight. (Source)

2. The Monarch caterpillar is a voracious eater and they can gain about 2700 times their original weight!
Monarchs must consume A LOT of food in a short amount of time in order to have enough food stored to go through metamorphosis. Monarchs literally outgrow their skin FIVE times. These sheds or molts are called "instars". Once the caterpillar has reached their fifth instar, they will find a place to pupate.
3. Two black spots on the inside surface of their hind wings distinguish male Monarch butterflies from the females.
It is helpful to know how to identify a male from a female Monarch when gardening to attract butterflies. If you notice a female on a milkweed plant, they are most likely laying their eggs there. You can then bring those leaves inside to raise your own Monarchs! Male and female Monarch butterflies are easily distinguishable. The females generally have thicker veins on their wings and they do not have black spots on their hind wings (which are actually specialized scales). In the case of most butterflies, these scales release hormones to attract females but they aren't sure that this is the case with Monarchs as well.
It can be a little more difficult to tell the Monarch's sex when their wings are closed but if you look VERY closely you can still see the black dot that indicates a male even when the wings are closed.
4. Monarch and Viceroy butterflies utilize Müllerian mimicry in order to mutually co-mimic each other and warn predators of their toxicity.
 | MThe main visual difference between the viceroy and monarch butterfly is the black line drawn across the viceroy's hind wings, which monarch butterflies do not have. The Viceroy is also a bit smaller than the Monarch. The caterpillars of Monarchs and Viceroys look very different as well. This is not merely a coincidence but a means of survival for these butterflies. There is a name for this phenomenon called Müllerian mimicry- “a form of mimicry in which two or more noxious animals develop similar appearances as a shared protective device”. |
 Viceroy caterpillar |  Monarch caterpillar |
It was long believed that the Viceroy used Batesian mimicry- “mimicry in which an edible animal is protected by its resemblance to a noxious one that is avoided by predators.” However, it was found that the Viceroy feeds on Willow species (cottonwood, willow, poplar trees) which contain salicylic acid, the active ingredient in aspirin and make them taste bitter to birds and other prey.
5. One female Monarch butterfly can lay an average of 300 and 500 eggs in the wild. Captive monarch butterflies average about 700 eggs per female over 2 to 5 weeks of egg laying, with a record of 1179 eggs in captivity!
According to a study done by Karen Oberhauser (1997), the average amount of eggs laid in 1994 was 715 (range 290–1179). It is difficult to know exactly how many eggs Monarch butterflies lay during their lives in the wild, but the average is estimated to be between 300 and 500.
Monarch females usually lay a single egg on a milkweed plant, often on the bottom of a leaf near the top of the plant. Eggs are only about the size of a pencil tip and are off-white or yellow, characterized by longitudinal ridges that run from the tip to the base. The eggs hatch about four days after they are laid (University of Minnesota, Monarch Lab).

6. Monarchs that emerge in the warmer months will become sexually mature within 5 days. However, migrating monarchs will emerge in reproductive diapause (suspension of reproductive development) and will not reproduce until Spring.
Environmental factors play a role in triggering this physiological response. These factors include day length, temperature, and host plant quality (University of Minnesota, Monarch Lab). Monarchs that overwinter in Florida and California, however, may not emerge in reproductive diapause because they do not migrate to Mexico. Migrating monarchs emerging in cooler temperatures will pause their reproductive duties until they return to warmer, more favorable conditions.

7. The Monarch's studded gold chrysalises are created by the coupling of a carotenoid pigment and a hill-like structure that reflects light from the peaks. They get the carotenoids from their diet of milkweed.
Monarch chrysalises shimmer in the sunlight like golden studded enclosures. In fact, word ¨chrysalis¨is derived from the Greek word ¨chrysos¨ meaning ¨gold.¨ What is the purpose of this beautiful feat of nature? Fred Urquhart was the first to study the gold spots on Monarchs in the 1970s. Interestingly enough, all danaine butterflies (monarchs and their relatives) have metallic spots on their chrysalises but how do they do this?
In monarch butterflies and a few others the gold is created by a coupling of a carotenoid pigment and a hill-like structure that reflects light from the peaks. They get the carotenoids from their diet of milkweed. If the caterpillars are fed an artificial diet lacking carotenoids then the would-be golden crown develops as silver in the chrysalis.
Here are some hypotheses for the reasons that Monarchs have metallic-looking spots on their pupae:

Here are some hypotheses for the reasons that Monarchs have metallic-looking spots on their pupae:
- Camouflage- the golden studs might increase their camouflage by looking like dew droplets on leaves and reflecting leaves on the surface
- Warning- to deter predators they might be showing aposematic or warning coloration
- Protecting from harmful sun rays (unlikely but who knows?)
- They might not have any function but just be the result of something else in the cuticle of the insect. (Source)
8. Monarch butterflies smell and taste with their antennae and legs which are covered with sensory cells called chemoreceptors. These chemoreceptors help Monarchs find milkweed to lay their eggs on.
Like Monarchs, when we smell and taste we are actually sensing chemicals in our environment. We also have chemoreceptors, which are concentrated on our tongue as tastebuds and in our nose. Monarchs use sensing chemicals in order to find their host plant, milkweed, quickly and accurately.
Dr. Bill Calvert describes what he observes in the field: "The female flits over the field and, when she stops on a plant, she drums the surface with her forelegs." She is basically putting tiny cuts into the plant in order for the chemicals to be released and for her to tell if it is indeed milkweed.
"Monarchs use a combination of visual and chemical cues to find milkweed," says monarch scientist Dr. Karen Oberhauser. "Once they land on a plant, they use sensory organs on their feet and heads to tell them if it is a milkweed, and probably the quality of the milkweed." (Journey North)

9. An overwintering Monarch typically lives 7-8 months compared to other generations that only live 2-6 weeks.
During the summer breeding season, monarchs live for only 2-6 weeks. But the monarchs that migrate to Mexico in the fall are different: They are born in late summer, stay alive all winter, and migrate north the following spring.

Did you know that Milkweed is one of the most useful and versatile plants in the world? Not only is it a vital plant-food for Monarchs, it is extremely useful for us as a source of food, medicine and fiber.
From it's historical uses in World War II to it's use as a nematicide, Milkweed's many uses may just surprise you!
Historical Uses
- The young shoots, flower buds, immature fruits, and roots of butterfly milkweed were boiled and prepared as a food-source by various indigenous groups of eastern and mid-western America throughout history.
- During World War II, milkweed quite literally saved hundreds if not thousands of lives. In 1943, a milkweed seed and floss-extracting plant was created in Michigan which provided the armed forces with over two million pounds of plant material used to stuff 1.2 million life-vests! (Berkman, 1949)
Medicinal Uses
- In 1892, Charles Millspaugh recorded the early medical history of butterfly milkweed, also known as pleurisy root. He stated that it is a proven remedy for certain forms of dry coryza, indigestion, colic, diarrhea, dry coughs, pleurisy, rheumatic pains, and some skin affections (1974, p. 540).
- The milky white sap is sometimes applied topically to remove warts.
Caution: Some people have allergic reaction to the milky sap and avoid contact with your eyes by washing hands thoroughly after touching. - Famous ethnobotanist, Melvin Gilmore, wrote that the Omahas and Poncas ate the raw root of the butterfly milkweed for bronchial and pulmonary troubles and also as a treatment for wounds (1977).
- The Lakota's name for green milkweed is "hu cinska" which describes the shape of the leaf. The pulverized roots of green milkweed were used to treat children with diarrhea (Rogers, 1980, p. 34). The Blackfeet also used the root of green milkweed to relieve sore throats (Hellson, 1974, p. 71).
Culinary Uses
- Common milkweed has been used for food by the Omaha-Ponca, Winnebago and Pawnee tribes in all three stages of it's growth, from young sprouts to floral buds to young fruits (Gilmore, 1977, p. 57)
- Experienced foragers still enjoy eating young milkweed sprouts (after being boiled) but only when identified properly. Refer to my Milkweed Identification blog if you aren't sure or pick up a field guide to help you. If you are confident in your identification skills are are looking for ways to prepare milkweed refer to Kay Young's book, Wild Seasons, for more ideas.
Note: All species of the Milkweed (Asclepias) family are known to contain cardiac glycosides that are poisonous to animals and humans. Monarchs have used these as their chemical defense against predators. Viceroy butterflies are a classic example of Batesian mimicry and also benefit from milkweed. Although they are not poisonous and do not eat Milkweed, predators confuse them for Monarchs and will avoid them.
Current Uses
- Milkweed is currently being commercially used for stuffing pillows and comforters which proves more cost-effective and sustainable then down or synthetic fibers (Nehring, 2014).
- The fluff of the milkweed pods prove to be a wonderful fire starter!
- In current research by the USDA, a chemical extracted from the seed is being tested as a pesticide for nematodes (O'kuru, 1999).
- Tewa-speaking people of the Rio Grande still make string and rope from these fibers
- Over the years, researchers have investigated growing milkweed for paper-making, textiles, and lubricants, and as a substitute for fossil fuels and rubber (Lohmiller).
We hope that Milkweed continues be grown and protected in order to provide sustenance, medicine, and a habitat for many creatures of the world, including humans!

Even though we are in the depths of winter, it is a great time to start planning your butterfly garden!
Reason's to start now:
- If ordering seeds, they may take weeks to arrive
- Thinking about Summer may just raise your spirits
- Native plants often need a stratification period of 30-60 days
- Starting the seeds indoors will ensure they are ready to go when Spring arrives
Here are a list of common butterflies as well as their host plants, preferred nectar sources and native range.
Remember, pollinators have evolved with their host plants and they will only lay their eggs on these specific plants. They also need nectar-sources once they reach adulthood. Having a combination of both host and nectar plants will guarantee a thriving butterfly garden!
Lastly, please source your seeds from certified organic companies and avoid the use of pesticides which are harmful to butterflies and other pollinators.
