2023 How to Raise Monarch Butterflies Indoors

Caring for monarch butterflies can be a rewarding and educational experience. By raising monarch butterflies indoors, you not only get to witness their extraordinary life cycle up close but also contribute to their conservation efforts. In this comprehensive guide, we will walk you through the step-by-step process of raising monarch butterflies indoors. From acquiring eggs or caterpillars to providing proper food and shelter, we will cover everything you need to know to successfully nurture these beautiful creatures. So, let’s dive in and discover the wonders of raising monarch butterflies indoors!

Why Raise Monarch Butterflies Indoors?

Raising monarch butterflies indoors offers several advantages. By controlling their environment, you can provide optimal conditions for their growth and development. Moreover, it protects them from predators, diseases, adverse weather conditions, and other environmental threats they would face in the wild. Additionally, when you raise monarch butterflies, you become actively involved in their conservation. Monarch populations have been declining due to habitat loss and pesticide use, and your efforts can help support their survival.

Acquiring Monarch Eggs or Caterpillars

The first step in raising monarch butterflies indoors is obtaining eggs or caterpillars. There are various ways to acquire them:

  1. Find Monarch Eggs: Search for monarch eggs on milkweed plants in your area. Female monarchs lay their eggs exclusively on milkweed leaves. Look for small white or cream-colored eggs, usually laid singly on the underside of the leaves.
  2. Visit Local Conservation Centers: Many conservation centers and butterfly gardens offer monarch eggs or caterpillars for sale or as part of educational programs. Check their websites or contact them directly to inquire about availability.
  3. Join Online Communities: Participate in online forums, social media groups, or local butterfly enthusiasts’ networks. Members often share surplus eggs or caterpillars, making it a great way to start your monarch butterfly-raising journey.

Creating a Monarch Habitat

To provide a suitable environment for the monarch butterflies, you will need to set up a habitat that mimics their natural conditions. Here’s how to create an ideal monarch habitat indoors:

A. Choosing a Container

Select a spacious and well-ventilated container to house your monarch eggs or caterpillars. Clear plastic containers or mesh cages specifically designed for butterfly rearing are excellent choices. Ensure the container has a secure lid or cover to prevent escapes.

B. Adding Suitable Substrate

Line the bottom of the container with a layer of paper towels or coffee filters to absorb excess moisture. This substrate also makes cleaning easier as it can be replaced when soiled.

C. Providing Food Source

Monarchs exclusively feed on milkweed plants, so it is crucial to provide fresh milkweed leaves for the caterpillars. Pluck young, pesticide-free leaves from milkweed plants and place them in small water-filled containers, such as vases or test tubes. Insert the stems into foam or floral tubes to keep the leaves hydrated.

D. Ensuring Proper Lighting and Temperature

Place the container in a well-lit area without direct sunlight. A combination of natural light and artificial lighting, such as fluorescent bulbs, can provide the necessary illumination. Maintain a temperature between 75°F and 85°F (24°C – 29°C) for optimal growth and development.

Raising Monarch Eggs and Caterpillars

Once you have successfully set up your monarch habitat, it’s time to raise the eggs or caterpillars to adulthood. Follow these steps to ensure their healthy development:

A. Handling with Care

When handling monarch eggs or caterpillars, always approach them gently. Use clean, washed hands or wear disposable gloves to avoid transferring harmful substances or bacteria onto the delicate creatures.

B. Monitoring Growth and Development

Observe the growth and development of the caterpillars closely. They will go through five instars, or stages, before transitioning into chrysalides. Provide fresh milkweed leaves regularly, removing wilted or soiled ones promptly. Make sure to clean the container regularly to maintain a hygienic environment.

C. Encouraging Pupation

As the caterpillars reach their final instar, they will search for an appropriate location to pupate. Offer suitable surfaces such as twigs, small branches, or artificial pegboards. Ensure these surfaces are securely attached and positioned vertically to allow the caterpillars to hang freely in a “J” shape before forming their chrysalides.

D. Creating Chrysalis Conditions

Once the caterpillar forms its chrysalis, avoid disturbing it. Maintain a stable environment with proper humidity levels. A well-ventilated habitat will prevent the formation of mold or fungal growth. Ensure the chrysalides are secure and protected from any potential disturbances.

E. Waiting for the Butterflies to Emerge

After the chrysalis stage, it’s time to patiently wait for the butterflies to emerge. This process can take anywhere from 10 days to several weeks, depending on the environmental conditions and species. Be attentive and observant, as you might get to witness the incredible moment when a butterfly emerges from its chrysalis.

Releasing Monarch Butterflies

The ultimate goal of raising monarch butterflies indoors is to release them into the wild. Follow these steps to ensure a successful and safe release:

  1. Wait for Wings to Dry: After emerging from their chrysalides, monarch butterflies need some time for their wings to dry and harden. Wait until they are fully ready for flight before releasing them.
  1. Choose a Suitable Release Site: Select an appropriate location for the butterfly release. It should be an open area with access to nectar-rich flowers and away from heavy traffic, pesticides, and other potential hazards.
  1. Time the Release: The best time to release monarch butterflies is during the early morning or late afternoon when the weather is mild. Avoid releasing them in extreme temperatures, strong winds, or rain.
  1. Gently Release the Butterflies: To release the butterflies, approach the habitat or container cautiously. Allow them to crawl onto your finger or hand. When they’re ready, gently lift your hand towards the sky and watch as these magnificent creatures take flight.
  1. Offer Nectar Sources: Once released, provide nectar sources such as flowering plants, especially those rich in nectar and preferred by monarch butterflies, such as milkweed, asters, goldenrod, and coneflowers. These plants will help sustain the butterflies and provide nourishment.

Frequently Asked Questions (FAQs)

Q1: How long does it take for monarch butterflies to complete their life cycle?

A1: The average lifespan of an adult monarch butterfly is around 2 to 6 weeks. However, the complete life cycle from egg to adult typically takes around 4 to 6 weeks, depending on various factors such as temperature and environmental conditions.

Q2: Can I raise monarch butterflies indoors without milkweed plants?

A2: No, milkweed plants are essential for monarch butterflies’ survival as they serve as the sole food source for their caterpillars. Without milkweed, it is not possible to raise monarch butterflies successfully indoors.

Q3: What are some common challenges in raising monarch butterflies indoors?

A3: Some common challenges include maintaining proper humidity levels, preventing mold or fungal growth, ensuring adequate ventilation, and providing suitable surfaces for pupation. Additionally, avoiding overcrowding and diseases are also important considerations.

Q4: How can I contribute to monarch butterfly conservation efforts?

A4: Besides raising monarch butterflies indoors, you can contribute to their conservation by creating monarch-friendly habitats in your backyard or community, planting native milkweed and nectar-rich flowers, reducing pesticide use, and supporting local conservation organizations.

Q5: Are there any legal restrictions or permits required to raise monarch butterflies indoors?

A5: The regulations regarding raising monarch butterflies may vary depending on your location. It is advisable to check with local authorities or conservation agencies to ensure compliance with any applicable laws or permit requirements.


Raising monarch butterflies indoors is a fascinating and rewarding experience that allows you to witness their incredible transformation up close. By following the steps outlined in this guide, you can create a suitable habitat, successfully raise monarch eggs or caterpillars, and release these majestic butterflies back into the wild. Remember, every effort counts in conserving these iconic creatures, so start your journey of raising monarch butterflies indoors and make a positive impact on their population. Happy butterfly raising!
