Cerro Pelón
Cerro Pelón is where scientists first confirmed that the butterflies migrated from Canada all the way to this Oyamel Fir forest in Central Mexico. Many butterfly enthusiasts and travelers will say that this is the most rugged and beautiful of the sanctuaries. I would have to agree that it was a lovely and private experience. Other than the arborists, ranger, and our guide we were the only people up there on the mountain.
The view on the ride up to Cerro Pelon
We booked our Cerro Pelon tour and stay through JM's Butterfly B&B. As far as I know, they are the only local guide company based in Macheros, the mountain village where the entrance to the sanctuary is. In fact, the entrance to the sanctuary is just a few minutes walk from JM Butterfly House and someone from the B & B will escort you. I highly recommend staying at JM's and booking a tour with them. Their guides, as well as Joel and Ellen are extremely hospitable, knowledgable and will give you the full butterfly experience! I was very excited to meet the Butterflies and Their People arborists.

It is a very steep hike up even for the experienced hiker. I opted for the horse and it was about an hour and 20 minute ride up the mountain at a fairly brisk pace (for the horse). Have no fear if you are not an experienced horseback rider because there will be a horse handler to lead you and your horse.
Once you arrive at a clearing at the top of the mountain, your handler will tie up your horse and it will be between a 15 and 25 minute walk to the colony of butterflies. Keep in mind that the length of time will vary considerably at different times of the season. I visited at the beginning of December. My guide, Ana, said that the Monarchs generally continue to move deeper into the forest and higher on the mountain as more butterflies arrive.

Sierra Chincua
This was the second most recommended sanctuary by the folks of JM Butterfly House and I was told it was less developed and less touristy than El Rosario.
My mother and I stayed in Zitácuaro the night before which is about an hour and a half drive from the sanctuary. We took a bus to Angangueo (also called Pueblo Mágico), a small mountain village with beautiful, colorful houses and a lovely cathedral. It is the perfect launch pad for El Rosario and Sierra Chincua, being just about a 30 minute taxi drive to either. I would recommend staying in this village if you get the chance.

It's easy to see how Angangueo got it's name Pueblo Magico (Magic Village).
After taking a bus from Zitácuaro to Angangueo for around 50 pesos ($2.50 USD), we took a taxi from the plaza of Angangueo to the entrance of Sierra Chincua for around 100 Pesos ($5 USD).
Important Note: Once up on the mountain in Sierra Chincua, public transport is very limited and you may want to arrange a ride prior. We were told that there is a combi (an outfitted VW bus) that arrives at 5:00 pm but we decided to have our taxi driver wait for us. The price for this will vary depending on your taxi driver but he told us he would wait 2 hours and take us back to Angangueo for 500 Pesos ($25 USD).

Sierra Chincua did not disappoint. Entry fee into the Sanctuary was 50 Pesos ($2.50) per person and renting a horse is 200 pesos ($10 dollars). It is also customary to tip your guide somewhere between 100 and 200 Pesos. There are also restaurants and souvenir shops at the entrance.
The horseback ride was much shorter than the one to Cerro Pelon and was only about 15 minutes up (although it is very steep). From there, it was about a 15 minute walk to the tree stand that is inhabited by the butterfly colony. It was a cloudy day and most of the butterflies were roosting in the trees. A different perspective than the sunny day we had in Cerro Pelon! Both views were absolutely stunning.

 Examples of the clearly marked signs within Sierra Chincua  There were a quite a few more people on the mountain here than in Cerro Pelon |   The butterflies roosting in the Oyamel Fir trees in Sierra Chincua |
El Rosario
Unfortunately, we didn't have time to visit El Rosario this year although we got close. From Angangueo, you can take a combi to the entrance which is about 30 minutes and will cost less than 50 pesos ($2.50 USD).
Here is a quote by Ellen Sharp from JM Butterfly House about El Rosario:
"Unlike the unmarked trail that winds up the mountain on Cerro Pelon, here you’ll find numerous souvenir stalls, large tour groups, concrete steps, interpretive signs, and a lot more guides making sure you don’t get too close to the colony. The hike up is mostly on a paved trail and it takes 30-45 minutes each way, depending on your speed and acclimation. A horse will get you there in 20 minutes. In recent years, El Rosario has been the most populous of the butterflies’ overwintering sites. "

Piedra Herrada
Again, we were not able to visit this site but here is a summary from JM Butterfly House:
"The trip from our place to Piedra Herrada takes you through the small farming villages of the State of Mexico on a road lined with fields of fruit trees and nopal cactuses. Then the road descends into the cosmopolitan colonial gem and weekend resort town, Valle de Bravo, which we visit on the way back. The sanctuary is another half hour down the road from here. The trail begins with a stone path with a separate trail for horses. The hike takes from 45 minutes to an hour each way."

Insider tips
Bring an extra jacket because it will always be colder in the sanctuary which is at an altitude of almost 10,000 ft or 3000 m. If riding a horse, you can ask to tie the coat onto your saddle.
Bring a water bottle, as it is important to stay hydrated especially in higher altitudes.
Arrange transportation beforehand and start out early. To maximize your time with the butterflies, it's good to be up on the mountain by noon.
Don't underestimate the hike. The elevation makes it much more difficult that it appears.
Watch your feet! Be careful not to step on a butterfly. It would be a shame to come all that way and accidentally step on a butterfly!
Consider bringing a hat for sun protection.
Help your horse out by leaning slightly forward on the uphill and leaning back on the downhill. On the downhill, press your feet into your stirrups to stabilize your body.
Our goal is to install over 5,000 Pollinator Gardens across the US and you can help!
We have received so many pictures and stories of successful School Pollinator Garden Projects and we want to encourage everyone to start one in their community! It’s very easy to get started and we are going to tell you how.
You don't need a lot of space to start a pollinator garden and just a few containers or raised beds can provide a habitat for hungry butterflies and bees. Having this outdoor classroom can encourage observation, exploration and a instill land stewardship values. Teachers can even build a curriculum around a garden, focusing on subjects such as: biology, environmental studies, writing, and art.

Did you know that most Milkweed seeds and many other perennial plants need a period of cold stratification in order to germinate?
 | Cold stratification is simply exposing the seed to a period of cold treatment. It is a pre-treatment method you can use to break the seed's dormancy and increase it's ability to germinate. This is something that occurs in nature and what we call "Winter". There are a various different methods to cold stratify seeds. I am going to explain the Outdoor Methods or, as I like to call them, "Mother Nature's Way". In my opinion, these are the easiest methods but they do take patience. The methods I will be explaining are very old ways of cold stratifying seeds that people have been using for hundreds of years. Although using a refrigerator to cold stratify seeds has become more popular in recent times, this is the way our ancestors have always done it. |
In using the Outdoor Methods, it is best to plant your seeds after the first frost. I live in Nebraska where the first average frost happens around October 5th. (click here to find out when your average first frost is). I am planting Common Milkweed (Ascepias syriaca) because it is the most common species of Milkweed growing in my area and I know it needs a cold stratification period.
The "Fall Planting Method"
Fall planting is a traditional method of cold stratification. The best time to plant Milkweed seeds in the Fall when the first frosts start to occur. I recommend planting them directly in the ground, however you can plant them in pots with some additional attention.
1. Choose an area where you want to grow your Milkweed plants. Make sure it has proper sunlight and is in a slightly protected area.
If planting in pots, make sure they are protected (i.e. against the side of a building or next to straw bales). Make sure the pots are not in the drip-line of the building so that they could potentially fill with water and then freeze. However, snow-melt is an important part of the process so do allow snow to cover the pot.
2. Sprinkle the seeds on the soil and mulch with a couple inches of straw or leaves.
Note: Do not pack the mulch down as it is important to have a bit of air flow to deter mold and fungus from growing.
3. Sprinkle water over the seed bed if soil is dry.
4. Mark the area so you don't forget where you planted.
5. Be patient. They will not germinate and start sprouting until Spring and sprouting will not occur all at the same time as with most cultivated varieties of plants. These are wild plants that will have more genetic variation and will be more likely to survive once they have become established.

The "Winter Planting Method"
This method is also called "Snow Planting". It is an easy, fun method that should spark the interest of children and adults alike!
During the winter after a heavy snow, broadcast your seeds out on the snow. Believe it or not, many of them will come up in the spring! The moisture will soften their seed coats and essentially wake them up.
Make sure it is in an area that you want the plants to grow and will have plenty of sunlight in the Spring and Summer.

Have fun!
Have fun experimenting with different methods of cold stratification. You can even plant a small batch of Milkweed seeds in the Fall, Winter and Spring! Why not? Each time you will learn something new and know what works best for your area next time. Don't give up and record your findings!
Stay tuned...
I have just covered how to sow Milkweed in the Fall and Winter in this blog. If you want to opt for the Spring planting stay tuned for Part 2 of the Cold Stratification 101. In the meantime, keep you Milkweed seeds in a dry, aerated envelope and store in a dark place for the Winter. If I plant in the Spring, I generally start the Cold/Moist treatment for Milkweeds 30-60 days before the last average frost in my area.
Save Our Monarchs recently released our Pandora Monarch Butterfly Charm and we went behind the scenes to see how they were made!
The Monarch Butterfly Charm was created by local glass artist from Nebraska, Matthew Losee, and the proceeds go to support Save Our Monarch's School Pollinator Program. The beads can be used on earrings, bracelets, necklaces, key chains and the list goes on! They also make thoughtful gifts to your Monarch-loving friends and family.
Each glass color is layered separately onto a mandrel beginning with black. The glass that is used is call borosilicate which is what Pyrex is made from and is extremely break-resistant.
Next, the unique "Monarch Orange" glass color is layered on.
Now for the distinctive white spots that we recognize on our Monarch friends.
Lastly, a clear layer of glass is added in order to magnify the image and they are put into a kiln.
Meet the Artist
| Matthew Losee, of Lincoln, Nebraska, has been blowing glass for 14 years and worked for 5 years with the Conservation Corps and US Forest Service to help conserve wilderness areas. His passion for environmental conservation and art spurred him to create a bead in the image of the Monarch. Save Our Monarchs was happy to combine forces in order to promote local art, conservation and the love of the Monarch butterfly. |  |
How do you use your Monarch bead? Please post in the comments ways in which you use yours!
The time has come to collect milkweed seeds if you haven't already. You can plant them next year, give them to friends and family, share with your community and/or donate them to your favorite Monarch conservation organization!
Where should I collect? You can collect Milkweed pods on private lands (with permission of course), public right of ways and road sides.
What if I'm not sure how if it's a Milkweed plant? All milkweed species develop a seed pod and they look very similar. Refer to the Milkweed Identification blog if you're not sure how to identify Milkweed.
How much should I collect? The rule of thumb for harvesting wild plants is to leave at least 2/3rds of the plant to ensure that the wild population will continue to thrive.

Step 1: Collecting the Milkweed Pods
The perfect time to harvest the pods is when they are just starting to pop at the sutures and the seeds are brown.
A milkweed seed pod that is mature and starting to release it's seeds. Timing is key when collecting milkweed seeds. Here are a couple of tricks to ensure that your seeds are mature and viable.
If the pod is brown and has already popped open releasing their silky fluff, also called coma, you know that they are ready and you can harvest them and remove the fluff later.
However, if you want to avoid the fluff and be able to take the seeds off neatly and easily, here is a little trick.
I look for green seed pods and the first thing I do is squeeze the seed pod. If I hear a gentle pop and see that the pod has split at the suture, then I look inside. If the seeds are a nice coffee brown then I know they are mature and I can collect the pod. However, If the seeds are white or tan, I don’t collect them and let them continue to mature on the plant.
Milkweed seeds can mold easily so I like to use a paper bag or cardboard box when I'm out collecting.

Step 2- Removing the Seeds from the Husk
This is a fun and relaxing activity. So, I’ve already collected my light green seed pods that have row after row of beautiful tightly packed seeds. I let them sit for about 2 weeks so they are dry and easy to remove (you do not have to let them dry this long). I open the pod at the suture and grab the narrow end of the pod then gently pull until the seed follicle comes out of the husk. Then, I rake my finger nail along the seed follicle, going WITH the grain of the seeds.

Step 3- Drying
After you remove the seeds, you’ll want to let them dry out for 3 days to a week. I like to let them dry on cardboard in a well-ventilated area. My porch works well for this.
Step 4- Storage
Once they have dried out, I store them in small manilla envelopes and date them. I do not store them in plastic bags because this will often cause them to mold.

Let's face it, pests are the bane of any gardener's existence.
Although pesticides can be helpful in managing garden pests, they also have a number of drawbacks including: potential toxicity to humans, pets and pollinators. In fact, millions of pollinators die each year due to pesticides and tainted Milkweed is a common factor in Monarch mortality.
Which begs the question: How do you get rid of the bad bugs while sparing your beloved pollinators and other beneficial bugs?
Although the best option is to avoid pesticides altogether, many gardeners can't imagine not using any pesticides at all. Therefore, this blog will discuss pesticides with the lowest toxicity to pollinators and tips for safely applying pesticides.
*Here is a list of EPA’s reduced risk pesticides that pose less risk to human health and the environment than existing pesticides.

*Here is a list of EPA’s reduced risk pesticides that pose less risk to human health and the environment than existing pesticides.
First off, What is a pesticide?
Pesticides are a broad category of substances that are meant to deter, kill or discourage various types of pests such as weeds, nematodes, plant pathogens or fungi. The term pesticide includes herbicides, insecticides, nematicides, fungicide and other pest deterrents.
10 Tips for Using Pesticides Safely
Know what type of insects you are targeting.
Do not treat flowering plants.
Do not spray where pollinators such as butterflies, bees and moths are actively foraging.
When possible, eliminate weeds by mowing or pulling.
Choose short residual materials and low-hazard formulations if insecticides absolutely must be applied during the flowering period to save the crop.
Apply insecticides when pollinators are no longer foraging such as in the evening or early morning.
Adjust spray programs in relation to weather conditions. If it is windy, do not spray.
Read the pesticide label.
When possible, remove bugs by hand.
Reduce pressure of spray nozzle to prevent pesticide drift.
If you choose to use pesticides, consider these safer options.
Keep in mind that no pesticides are completely safe to pollinators but if you follow these guidelines, you may be able to minimize your impact. This is a list of pesticides that are considered pollinator safe by the Michigan State University extension office.
Insecticidal soaps
Insecticidal soaps are most effective on soft-bodied insects such as aphids, adelgids, lace bugs, leafhoppers, mealybugs, thrips, sawfly larvae, spider mites and whiteflies. They are not effective on pests as a residue on the plant surface, and therefore are not toxic to pollinators after the spray dries. They can be safely used at any time to control pests on plants that are not attractive to pollinators, but on pollinator-attractive plants spray at dawn or dusk when pollinators are not present.
Horticultural oils
Like insecticidal soap, horticultural oils work best when the spray comes in contact with the pest. Once the oil spray dries, it does not have much effect and becomes safe for pollinators and other beneficial insects. Horticultural oil can be safely used at any time to control pests on plants that are not attractive to pollinators, but on pollinator-attractive plants they should be sprayed at dawn or dusk when pollinators are not present.
Bacillus thuringiensis (B.t.)
While a B.t. strain works well for its target pest, it also breaks down quickly in sunlight, becoming ineffective after a few days. This makes B.t. very safe for pollinators, predatory insects and mammals. B.t. can be sprayed even when bees or butterflies are present.
Metarhizium
The fungus Metarhizium anisopliae is found naturally in soils and infects and kills insects. M. anisopliae does not detrimentally impact honey bees and is being studied as a bio-insecticide of varroa mites, a pest of honey bees.
Spinosad
Spinosad is highly toxic to bees. However, toxicity is greatly reduced once the product has dried on the foliage, within three hours to one day depending on the product. Therefore, avoid use if bees are active, and if applications are needed, apply in the evening when bees are not active and product has time to dry. This product suppresses a broad number of caterpillar species and should not be sprayed or allowed to drift in known habitats for threatened or endangered species of caterpillars and butterflies.
Pymetrozine
As a caution, apply pymetrozine in the evening, night or early morning when bees and butterflies are not visiting blooming plants. Since this product is selective for aphids and whiteflies, there should be no impact on other pollinators or natural enemies.
Acequinocyl
Acequinocyl is considered nontoxic to bees and can be applied at any time. Since acequinocyl is selective for mites, other pollinators and natural enemies should not be affected.

Many people have been asking, “What's wrong with my Monarch caterpillar/egg/chrysalis?”
This is a list of the MOST common problems that the Monarch Rearer may encounter and how you can either avoid your Monarch from being infected or avoid the infection from spreading to your other caterpillars. Hopefully these tips and indicators can help you raise healthier Monarchs in the future!
Warning: Some photos may seem graphic or unpleasant.

Warning: Some photos may seem graphic or unpleasant.
UPDATE: Flea and tick treatment along with several cleaning products in your home can be deadly to Monarchs caterpillars.
We recently received this tip from one of our readers.
Any flea or tick prevention given to cats or dogs, both topically applied and orally administered, are toxic to Monarch larvae.
Allowing your treated cat or dog to rub against your Monarch's cage can cause harm or death to the caterpillars inside. Petting your animal after treatment and then gathering milkweed leaves or touching anything in your Monarch's cage can harm your caterpillars.
Also, be aware of any potentially toxic cleaning products you may be using around your caterpillar cage such as Febreeze, other air fresheners, carpet cleaners, Windex, or Lysol. Remember that these are very delicate creatures and even small doses of chemicals can be fatal.
Prevention: Whenever interacting with your Monarch caterpillars make sure you washed your hands prior and/or wear gloves to be sure that your hands are free of any chemicals. Try to use natural cleaning products inside the room your caterpillars are living.
Any flea or tick prevention given to cats or dogs, both topically applied and orally administered, are toxic to Monarch larvae.

Black Death
What is Black Death?
As the name suggests, this is a fatal and very unpleasant ailment for the Monarch. Black Death is a general yet appropriate term used to describe the effects of two different infections. Pseudomonas is a bacteria that thrives in moist environments and Nuclear polyhedrosis virus (NPV) is a virus.
How to tell if your Monarch has Black Death:
Your caterpillar may be fine one day and the next start to become lethargic, start to deflate, refuse to eat and start to turn a darker color. Sometimes their chrysalises will turn dark brown or they pupate and then liquefy into a black goo. This can be a traumatic experience for the Monarch Rearer but once your caterpillar has contracted Black Death, it is nearly impossible to save them and the best thing to do is remove it immediately from the cage and disinfect anything it may have touched in order to prevent it from spreading to other caterpilalrs.
Note: NPV causes the caterpillar to climb to a high spot, hang in an l or inverted V shape, and die. The caterpillar then liquefies inside and when the skin of the caterpillars splits open, the black goo will send millions of virus particles on its surroundings. The smell is very pungent. If a caterpillar lies at the bottom of a rearing container (instead of crawling higher in the container) and dies either firm or mushy, it is not infected with NPV.

How to prevent Black Death
- The Pseudomonas bacteria like moist, warm environments so try to keep your butterfly cage dry, well-ventilated and out of direct sunlight.
- Clean the frass (butterfly poop) everyday and disinfect the tray before putting it back in the cage.
- Gently rinse and dry milkweed before putting into your cage.
- If you see any signs of an unhealthy caterpillars or chrysallises (read indicators above), isolate it from the other caterpillars.
O.E. (Ophryocystis elektroscirrha)
What is OE?
OE is a protozoan parasite that is spread through microscopic spores coming off the wings and bodies of adult butterflies. These spores are packed in between scales on the Monarch's body and when it lays eggs, often attaches to the egg shell. Because OE is a parasite, it relies on a living host and will generally not kill Monarchs but will lead to weakness, disfigurement, and lethargy. Eventually it may die from sheer exhaustion.
How to tell if your Monarch has OE:
You won't be able to tell if a Monarch has OE until it's in the pupal or adult stage. Infected chrysalises won’t have a uniform green color. You can check your chrysalis closely to make sure it's dark spots are mirrored on both sides. Heavily infected Monarchs may not emerge or if they do they may be deformed or too weak to hold on.

How to prevent OE:
- Gentry rinse off milkweed with water before giving it to your caterpillars
- Clean out frass and disinfect the cage everyday
- In warmer regions where tropical milkweed grows all year, cut plants back to 6″ twice a year so fresh healthy foliage can emerge.
Tachinid Flies
What are Tachinid Flies?
Tachinid flies can be difficult to differentiate from other flies in your garden. However, if you look closely, you will see that they are hairy and have huge red eyes.

How tell if your Monarch was infected by a Tachinid Fly:
This is one of the easiest Monarch infections to identify. They lay eggs on monarch caterpillars and once hatched, the maggots will bore into the caterpillar and feed on them while they are still living. You can generally tell if your caterpillar has been infected if it suddenly gets much skinnier and will sometimes die while attempting to form it’s chrysalis. These flies also lay eggs inside chrysalises. After it’s host has died, the maggots will emerge, leaving tell-tale white strands of silk hanging from the caterpillar or chrysalis.

How to prevent Tachinid Flies:
- Closely inspect monarch caterpillars before bringing them inside and choose ones that are second Instar or even smaller.
- Keep a close eye on your caterpillars and eggs
Pesticide Poisoning
Sadly, it occurs quite often where nurseries treat their milkweed with pesticides or roadsides/fields are sprayed where you collected milkweed/caterpillars unknowingly.
How to tell if your Monarch has come into contact with Tainted Milkweed:
If your caterpillar has ingested pesticides it will often expel green vomit.
How to avoid this from happening:

If your caterpillar has ingested pesticides it will often expel green vomit.
How to avoid this from happening:
- If you notice your caterpillar vomit, gently rinse off the caterpillar under water and put it on a different (untreated) milkweed plant immediately.
- Plant a large amount of milkweed in your garden so you don’t have to buy milkweed elsewhere
- If you have to buy milkweed from a nursery, ask if they have been treated with ANY pesticides
- If there isn’t a local provider close to you, check online for untreated milkweed seeds .
- Proceed with caution even when companies list their products as safe for beneficial insects. Even organic products can be unsafe for caterpillars such as Neem Oil and Diatomaceous Earth
Trichogramma Wasps
What are Trichogramma Wasps?
They are tiny parasitic wasps that inject a single egg into the eggs of the pest. After consuming the contents of its host egg, a new adult wasp will emerge within 10 days.
How to tell if your Monarch has come into contact with Trichogramma Wasps:
If your egg turns completely dark keep an eye on it for the next couple of days to make sure a Monarch doesn’t hatch. If it doesn’t hatch, squeeze the egg inside of the leaf and dispose of the leaf.

How to avoid:
- When gathering Monarch eggs, try to get them inside right away
Chalcid Wasps
What are Chalcid Wasps?
This is another tiny, parasitic wasp that waits for the perfect moment to attack your beloved caterpillar. It will approach when the caterpillar is in it’s vulnerable “J” stage and wait for it to form a chrysalis. Then, right afterwards, it lays hundreds of its eggs in the soft chrysalis.
How to tell if your Monarch has been infected by Chalcid Wasps:
Look for small black dots where it appears they have deposited their eggs.

How to avoid:
- When gathering Monarch eggs, try to get them inside right away
- Use fine mesh enclosures to raise monarchs. Larger holes in laundry baskets will allow these impossibly small wasps access to your monarchs during this most-vulnerable time.
- If raising outdoors, do not leave your habitat open for long periods while cleaning and check the cage for flying insects before closing
Anal Prolapse
When this occurs, the caterpillar’s rectum protrudes from its anus, leaving a bright green ball at the end of your caterpillar. It’s not known what causes this, but it’s always fatal to the caterpillar.
