Supply List For Raising Monarchs
Welcome to Raise the Migration 3, where you’ll be raising magnificent monarch butterflies to help increase the number of monarchs that will be overwintering in the mountains of Mexico and southern California.
My name is Tony Gomez, and I’ve raised thousands of monarchs over the past 30 years. My goal is to help you learn how to raise more monarchs with less effort, while helping the struggling monarch population recover.
Who is Raise the Migration for?
- Those concerned with saving the monarch migration for future generations
- Those who want to raise healthier monarch butterflies
- Those looking for a more efficient process to raise monarchs
- School teachers and kids looking for an exciting (and educational!) way to start the school year
- Those interested in joining a passionate community of Monarch Enthusiasts
Feel free to share this post with others you think would be interested in participating!
How Many Monarchs Will You Raise?
This challenge was created for anyone raising between 1-20 monarchs at one time. If you want to raise more, I recommend using additional cages to avoid potential diseases caused by overcrowding.
Do You Have To Start On An Exact Date?
It’s unlikely that we would all have new monarch eggs on exactly the same date. Therefore, I will start sending tips during the earliest part of the migration, so you can refer to them when you have monarch eggs or caterpillars secured.
My tentative start date is Saturday, August 15th, 2015. This should allow most northerners to still participate and get their monarchs headed south before the weather becomes an issue. My start date might be a few days later depending on how cooperative the ELF’s (egg laying females) are. I will send out an announcement as soon as Raise The Migration begins.
When Will The Monarch Migration Be In Your Region?
Check out this monarch migration chart from Monarch Watch. I would recommend releasing your butterflies no more than 2 weeks after the last date of your peak migration. My latitude in Minneapolis is 45° N so my last peak date is September 10. This means I will try to release my last butterflies by September 24th.
You do not need to follow along in real-time to participate! Refer to the raise emails you will be receiving and start at a time that makes sense for your your region.
Does It Matter Where You Raise Them?
Keep in mind, cool nights below 55° F will slow down the metamorphic process. It’s very possible to have cooler nights in late summer (especially north) so bring your cage indoors on these nights, if your raising cage is outside. We raise ours inside a 3-season porch.
Before we get started, you will need to get set up with a few basic supplies. These supplies will help you raise monarchs for years to come, and they should fit most budgets. Some of you might not need to spend anything if you’ve already got the supplies at home.
To raise migration butterflies “the easy way” requires a cage that can hold a potted milkweed plant or stem cuttings:
Fantastic side-opening mesh cages for raising monarch caterpillars. This 4 foot high cage can also fit potted plants. At the end of the season, the cage folds flat for easy storage.
If you want to raise fewer caterpillars and plan to raise exclusively on cuttings, the 2.5 foot high cage is a good option. You could also use this exclusively as a cage to sun dry butterflies before releasing them.
These hard, plastic containers are perfect for raising caterpillars if you place pantyhose over the cage lid. This prevents small caterpillars from escaping, and you can still secure the lid. The XL cage is still a foot high and can fit small cuttings.
If you want to raise monarch butterflies on milkweed with the least amount of effort, you have two options:
- large potted milkweed plants with healthy leaves
- milkweed stem cuttings from potted or garden plants
The best place to find milkweed plants is in your garden or from a local nursery that doesn’t spray with harmful pesticides. Remember, systemic pesticides can not be rinsed off and remain inside the milkweed leaves.
2a. Tropical Milkweed (Asclepias curassavica)– this seems to be the preferred egg laying milkweed late in the season. If you have tropical mw in your garden, transfer one to a pot now and you’ll be good to go.
2b. Swamp Milkweed (Asclepias incarnata)– first and second year plants are usually the best options since many still have fresh leaves late in the season.
2c. Goose Plant (Asclepias physocarpa)– this milkweed always has viable, healthy leaves late in the season. It’s also easy to pot if you have some in your garden.
2d. Giant Milkweed (Calotropis gigantea)– this is not widely available but could be an option in places like Florida.
2e. Popular native species like Butterfly Weed (Asclepias tuberosa) and Common Milkweed (Asclepias syriaca) are usually past their prime by late summer. However, you can use them if the leaves are still green and appear healthy.
If you can’t find milkweed plants locally, some of the stores on my resource page might have plants in stock:

During the past decade, it has become increasingly difficult to find monarch eggs. If you don’t want to wait for your milkweed to work its magic, check out these sources to buy eggs and caterpillars.
If you want more of a ‘sure thing’ when ordering monarchs, caterpillars are probably your best option since a % of eggs won’t hatch.
The uses for these supplies will be explained (in detail) during Raise the Migration:
Choose one of the following 3 options:
4. Empty plastic bottle, empty jar, or vase to place stem cuttings cuttings
5. Small plastic food storage containers for shorter stem cuttings
6. Floral tubes for stem cuttings or individual leaves
Even if you are attempting to raise on potted plants, if you run out of milkweed you will have to use stem cuttings or even individual leaves
7. Pruning shears to take cuttings
8. Plastic wrap to cover empty bottle/vase
9. Rubber bands to secure plastic wrap
11. Duct Tape
12. Cotton Balls
13. Aluminum Foil
Choose one of the following 3 options:
14a. Oranges or Watermelon- in case you need to keep monarchs overnight due to inclement weather
14b. Gatorade can also be used to feed adult butterflies. Melon flavored gatorade has been suggested by universities.
14c. Sugar or granulated hummingbird food can be mixed with water and fed to butterflies with soaked cotton balls.
16. Small handheld vacuum for cleaning up frass (caterpillar poop)
Some of these items are optional (depending on your raising set up) and some of these items will already be in your home. Being prepared in advance will give you more time to enjoy this amazing experience…
