What Do Monarch Caterpillars Eat In Captivity?

Monarch caterpillars are specialists in their diet, exclusively feeding on milkweed plants (genus Asclepias). They are voracious eaters, consuming up to 200 times their body weight in milkweed leaves over their development. This diet provides them with the toxic chemicals they need. Monarch butterflies rely on specific plants for their food sources, and their caterpillars feed exclusively on milkweed plants. Native nectar plants are essential to provide energy for adult butterflies, including a variety of nectar.

Monarch caterpillars have a distinct way they feed on milkweed leaves, and if you carefully examine the plant, you’ll spot the presence of monarch caterpillars almost immediately. Milkweed stem cuttings can be taken in various sizes and placed in various containers filled with water. Instar 4-5 caterpillars (over a half-inch long) have been reported to eat pieces of butternut squash, delicata squash, pumpkin, and crunchy cucumber.

Monarch caterpillars can be raised by anyone, and the more people that raise them, the better their chances of survival. They eat multiple sources, including eggs, caterpillars, leaves, and milkweed. Recommended food for adult butterflies includes gatorade (but not red – it stains), juice, artificial nectar, and fresh cut fruits.

In captivity, monarch caterpillars prefer Swamp Milkweed (Asclepias incarnata) but also like other plants like carrots, parsley, fennel, dill, and carrots. To ensure the health and survival of monarch caterpillars, it is important to provide them with a clean and suitable environment, remove debris or waste from their enclosure, and provide fresh milkweed leaves daily.

What To Feed Monarch Caterpillars In Captivity?

Monarch caterpillars exclusively consume milkweed plants (genus Asclepias) throughout their life as larvae, a vital source of nourishment that provides toxins beneficial for their development. While some enthusiasts have had limited success feeding caterpillars butternut squash, it is essential to prioritize milkweed as their primary diet. Raising healthy monarchs involves a thorough understanding of their life cycle and dietary needs, ensuring access to fresh, healthy milkweed leaves, and avoiding contaminated or unhealthy specimens.

It's suggested not to capture caterpillars until they reach the butterfly stage, as survival rates drop in captivity. To support adult monarchs, provide various native nectar plants for energy.

What Can I Feed Monarch Caterpillars Besides Milkweed?

Monarch caterpillars exclusively consume plants from the Milkweed family (Asclepias spp.), which is essential for their survival. Contrary to some beliefs, these caterpillars do not feed on tomato plants. To support them in wildlife gardens, it’s crucial to incorporate milkweed plants. Common varieties available in New Zealand include the Swan Plant (Gomphocarpus fruticosus), the Giant Swan Plant (Gomphocarpus physocarpus), and Tropical Milkweed - Bloodflower (Asclepias curassavica).

While milkweed remains the primary food source, older, larger caterpillars may partially utilize alternatives like pumpkin, cucumber, and butternut squash, although smaller caterpillars cannot consume these options.

Research emphasizes that milkweed is vital for providing both nutrition and shelter to monarch caterpillars. Without it, they cannot thrive, as it is their sole food source. Sunset and shelter are also critical roles played by milkweed in monarch habitats.

Though other foods may be tried, such as pieces of various squashes or cucumbers, there is no true substitute for milkweed, and its shortage has raised concerns among enthusiasts. The successful migration of monarchs hinges on adequate milkweed availability. To contribute positively, planting milkweed and nectar-producing plants is encouraged. Additionally, Echinacea sp. (Coneflowers) offer support to monarchs and other pollinators. While alternative feeding methods are being explored, more research is needed to understand the long-term implications on the butterflies’ health and migration success.

How Do You Keep Caterpillars Alive In Captivity?

To successfully care for a caterpillar, you need to provide fresh food from its host plant, ensure it is safe from drowning, maintain proper ventilation, and offer a suitable place to pupate.

Therefore, conserving and expanding milkweed habitats is essential for the survival and resurgence of monarch butterflies, ensuring that their remarkable annual migrations continue for generations to come.

What Do Caterpillars Need To Survive In A Jar?

If you find caterpillars in the wild, it's important to create a suitable habitat for them. A large glass jar or small aquarium is ideal, but ensure it has a secure lid and ample breathable air, which can be achieved using mesh or cheesecloth instead of just holes. The best time to look for caterpillars is during spring and summer, as most moths and butterflies lay eggs then. Nevertheless, some caterpillar species, like the woolly bear, appear in autumn, while winter is the only season they cannot be found.

Caterpillars can survive in simple enclosures. A one-gallon jar, fish tank, or reptile house can work well, provided there is good ventilation. To keep a caterpillar healthy, include its food plant in the habitat. Place the plant's stems in a small jar of water, ensuring that the caterpillar can access the fresh leaves without drowning. Fortunately, caterpillars don't need anything fancy for housing, as a clean container will suffice.

Creating a caterpillar habitat can be straightforward; for similar control while allowing mobility, consider a bucket or container. Key requirements for caterpillars include fresh food from their specific host plant, adequate ventilation, safety from drowning, and a secure area to pupate or transform into a chrysalis. You can keep caterpillars in jars with air holes or fabric covers, or even outdoors on a branch of a host plant. They get their moisture from the plants they eat, so there's no need to provide water directly.

If caring for a caterpillar, remove the plant stem it feeds on and place it in a suitable container for transport. Common host plants include dandelions and clover, but small pieces of apple or carrot can also suffice.

Is It OK To Raise Monarch Caterpillars Indoors?

Raising monarch caterpillars indoors may appear beneficial for conservation, yet it risks unintentionally spreading parasites such as Ophryocystis elektroscirrha (OE). While raising monarchs indoors is possible, it's discouraged as those raised outside may migrate more successfully. To rear them indoors, you need two plastic containers: a small one for the eggs and the caterpillar's first week, and a larger one for their second week. Eggs can be gathered from milkweed plants. If you opt for captive breeding, limit yourself to 5-10 caterpillars per year, providing an environment that closely resembles their wild habitat.

Involving children in observing metamorphosis can nurture appreciation for nature. The Xerces Society supports this, but advocates for caution. Although some enthusiasts raise multiple caterpillars, care is essential. Capturing found eggs and immediately releasing the mature butterflies may be more acceptable. Raising a couple of caterpillars can serve educational purposes or contribute to community science projects, while most efforts could be directed towards broader monarch support initiatives.

A suitable location includes a sunlit screened porch to provide natural light. While monarch caterpillar rearing isn’t complex, improper methods can harm these butterflies. It’s common for enthusiasts to bring caterpillars indoors for safety. While indoor upbringing theoretically leads to more successful hatching, it poses risks like parasite increase, potentially impacting wild populations. Handling caterpillars is safe for humans but can be risky for the insects. Despite these concerns, many individuals are keen to learn how to nurture monarchs at home. Overall, raising monarchs requires careful planning and a balanced approach to conservation.

What Is The Best Container For A Monarch Caterpillar?

Monarch larvae can be reared in various containers, including aquaria, glass jars, and plastic food containers. It's essential for these rearing containers to be at least three inches deep with ventilated lids, which can be mesh or have holes poked for airflow.
