5 Steps to Rearing Monarchs at Home

6/19/2018

4 Comments

 

Why raise Monarchs at home?

In the wild, Monarch eggs and larvae have a very small chance of survival.
Several studies have documented mortality rates of over 90% during the egg and larva stages (Borkin 1982, Zalucki and Kitching 1982, Oberhauser et al. 2001, Prysby and Oberhauser 2004).
That means only 10% of eggs and caterpillars will reach adulthood!

Not only is it a fun activity for the whole family but you are actually helping out an entire species while witnessing the phenomena called complete metamorphosis.

Still not convinced?

What if I told you it’s easy to rear Monarchs at home? All you will need to get started is a ventilated box (deli containers work great), a few milkweed plants and, of course, your Monarch egg or caterpillar.  The entire process from egg to adult butterfly takes about 1 month. 

But first...

It's important to understand the life cycles of a Monarch before you get started. Monarchs go through complete metamorphosis in which there are four distinct stages of growth in one life cycle! These stages are: egg, the larvae (caterpillar), the pupa (chrysalis), and finally adult butterfly. ​ 

Life Cycle of a Monarch

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, leading monarch conservationist, 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)

Once the Monarch larvae has reached their final molting stage, they will spin silk from which they hang upside down by their last pair of prolegs and create a chrysalis. They will spend between 1 and 2 weeks inside the chrysalis.

Adult Butterfly

Before the butterfly emerges, the chrysalis will turn from green to clear like in the picture below. ​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.

Materials Needed for Raising Monarchs 

1. Milkweed 
​Make sure you have a local nursery that you can acquire milkweed plants from or you already have some established in your yard because Monarch caterpillars can eat up to 200X their own body weight! Click here for types of Milkweed that are suitable for rearing Monarchs. 
2. Monarch caterpillars or eggs- These can be found outside on milkweed plants or purchased.
3. Ventilated container such as a deli container or aquarium works great. You can also buy butterfly houses like these. 
4. Paper towels

5 Steps to Raising A Monarch at Home

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 if you planned ahead, are already in your backyard! If you don’t have any luck finding milkweed plants or caterpillars, you can also order monarch rearing kits like this that contain caterpillars ​

Step 2: Choose a container

Put the eggs or caterpillars in a container and line with paper towels. Here are some great butterfly container ideas. 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 few days and you can replace the bottom of the container with more paper towels. You can even sprinkle it on your plants outside to give them a nitrogen boost!

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 a beautiful silken chrysalis. 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.

Why is it important to learn how to identify butterflies?

Learning some of the most common butterflies in your area will help you to understand what kinds of butterflies you are attracting to your yard. If your goal is to help endangered species, this is a great place to start!

​In the United States and Canada, there are more than 750 species of butterflies! Much of their habitats are being lost on a daily basis due to human activity (agriculture, roads, insecticides, herbicides etc.) However, you can help them by building habitat in your own backyard!

Click here to learn more about endangered species of butterflies.

10 Butterflies That You May Have Seen Before

  • Monarch (Danaus plexippus)​
  • Painted Lady (Vanessa cardui)
  • Cabbage White (Pieris rapae)
  • Black Swallowtail (Papilio polyxenes)
  • Eastern Tiger Swallowtails- (Papilio glaucus)
  • Orange sulfur- (Colias eurytheme)
  • Mourning Cloak- (Nymphalis antiopa)
  • Regal fritillary
  • Spring Azure- (Celastrina ladon)
  • Viceroy (Limenitis archippus)

Monarch- Danaus plexippus

How to Identify:
The monarch butterfly is one of the most iconic species of butterflies although it is sometimes confused with it’s lookalike butterfly, the Viceroy. The upper side of the male is bright orange with wide black borders and black veins. The upper side of the female is more of an orange-brown with wider black borders than the male.

The Viceroy butterfly mimics the Monarch in order to deceive predators. The main physical difference between the monarch and the viceroy is the black line drawn across the viceroy's hind wings, which monarch butterflies do not have. Viceroy butterflies are also significantly smaller than Monarchs. Click here to read a blog about the relationship between viceroy and monarch butterflies.

Where are they found? The monarch is found in a variety of habitats including fields, meadows, weedy areas, marshes, and roadsides. They also complete an annual southward migration from the northern and central United States and southern Canada to Florida and Mexico
What plants do they like?
Host and Nectar plant: Monarchs cannot survive without milkweed. Monarch caterpillars only eat milkweed plants (Asclepias spp.), and they also only lay their eggs on Milkweed. Due to the loss of habitat and the disappearance of milkweed, Monarchs populations are decreasing drastically.

​Not sure where to find milkweed? The Xerxes Society has created a handy database where you can search your state and it will list where you can find native milkweed nearest you.
You can also buy milkweed seed here and grow it yourself at home!

Regal Fritillary

Picture
How to Identify: The regal fritillary is a large butterfly that is smaller in size to the monarch butterfly. The upper side of the forewing is bright red-orange with black markings. The upper side of the hindwing is black with a row of white spots and on the wing edge is a row of spots that are orange in males and white in females. 

Where are they found? The regal fritillary is found on the Great Plains and is associated with tallgrass prairies, meadows and pastures.

What plants do they like? The larvae feed on violets. The adults feed on a variety of flowers such as milkweeds, thistles, clover and purple coneflower. 

There is an urgent call to track Regal Fritillary butterflies.
The Wildlife Conservation Fund created a citizen science project to monitor regal fritillaries, as well as monarchs, which are similar in appearance.

Natural Pest Control 101

6/6/2018

3 Comments

 
Picture

One of the biggest factors contributing to the loss of Monarch butteflies and Milkweed is the use of pesticides and herbicides. Many pesticides contain neonicitinoids and glyphosates that are deadly to beneficial pollinators and Milkweed. 

Harmful herbicides and insecticides are used generously in agriculture as well as in gardens. For a list of garden products that contain these harmful ingredients click here. 

​What are neonicitinoids?

Neonicitinoids are a class of broad-spectrum insecticides that are very commonly used in agriculture as well in urban gardens. They are systemic which means the plants absorbs the compounds into its tissues and distributes them into its roots, leaves, and flowers. Thus, making the entire plant toxic to insects that feed on it, including pollinators such as bees and butterflies. They are harmless to humans in small doses but they attack the central system of insects, acting as a neurotoxin. ​

What can I do to help?

You can help by providing habitat, no matter how small, and by protecting the monarch by using natural pest control methods on your milkweed and other pollinator plants. ​ Below you will find a list of natural pest control methods that will not harm beneficial insects like monarchs.

Pepper and Garlic Spray

How to make it:
For a strong spray, crush 3 cloves of garlic and add 3 tablespoons of hot pepper flakes to a cup of boiling water. Allow it sit overnight. Strain out the garlic and pepper flakes in the morning. Adding a dash of dish soap or vegetable oil can also improve effectiveness. 

Used for: All garden pests. 

How to use it:
​Spray directly on the plant. Make sure to get the underside of leaves where many pests lay eggs. You can use this spray daily if you have a pest problem or less regularly as pest prevention. 
Picture

Kaolin Clay

What is it?
Kaolin Clay is a natural mineral that is used for insect control on plants. It creates a thin barrier on the leaves which adheres to insects, causing excessive grooming, and thereby eliminating their urge to scavenge on the plant.

Used for: The use of Kaolin clay in the garden has been found to not only control insect pests but also protect the plant against sunburn or heat stress. You can purchase it online. 
​
How to use it:
To use Kaolin clay on plants, it must first be mixed with water and applied via a spray bottle. The clay particles are very fine therefore the spray bottle must continuously be agitated and applied liberally. 

  • Mix 1 part Kaolin clay to 8 parts water and add an extra dash of dish soap
  • Re-apply Kaolin clay for plants every week for at least 4 weeks
  • Insect control should occur within three applications
Picture

Neem Oil

What is it?
Neem oil is derived from the Azadirachta indica evergreen tree native to the Indian subcontinent. Neem has a long history of being used in the garden as a natural insect repellent. 
​
Used for: mites, including aphids, white flies, snails, nematodes, mealybugs, cabbage worms, gnats, moths,cockroaches, flies, termites, mosquitoes, and scale.

How to use:
Spray directly on the plant, including the bottoms of leaves.

Diatomacious Earth

What is it?
Diatomaceous Earth is  made of fossilized shells of tiny organisms called diatoms. It looks like a white, chalky powder.          

Used for:
aphids, mites, ants, thrips, slugs, snails, and other soft bodied insects

How to use:
​Shake powder onto leaves or at base of plant OR mix with water to make a spray. It will cut soft parts of insects which kills the insects by dehydrating them.
