Finding monarch eggs and caterpillars is an exciting experience, especially if it's your first time! It can be a bit more difficult to find immature life stages of monarchs compared to the showy adult monarch. However, when you know what signs to look for, it can be much easier!
If you are wondering when to look for monarch eggs, check the Journey North Monarch Egg Map to find out when they will be in your area!
On the Trail of Monarch Eggs
The best place to look for monarch eggs is on milkweed because it is the only plant that adult monarchs lay their eggs on. The trick is to look on the underside of the leaf but you may sometimes find eggs on the stems or flower buds as well.
**It is important to be very careful when handling milkweed leaves so you don't accidentally crush or disturb monarch eggs. Caterpillars can drop off of plants if disturbed. Pinch the very tip of a leaf and carefully turn it over without shaking the plant.**
Identifying Monarch Eggs
Monarch eggs are about the size of the head of a pin. In other words, very tiny! You may want to use a visual aid such as a jeweler's loupe or camera lens in order to identify the monarch egg. The egg is unique looking in that it is ovular, ribbed and somewhat transparent.
A monarch is in the egg stage for 3-8 days. In order to hatch, it has to eat the eggshell and then begins feeding on the leaf. A single caterpillar can defoliate an entire milkweed plant and sometimes more depending on the plant's size.
Signs of Monarch Caterpillars on Your Milkweed
There are several tell-tale signs that a monarch caterpillar has been on your milkweed. One thing to look for is milkweed leaves that have been chewed on, also known as signs of herbivory.
Another sign is small dark bits of frass, another word for insect droppings.
Monarch caterpillars go through five instars, or stages between molts. First instar caterpillars are very small and can appear almost translucent or pale green. Subsequent instars are distinctly striped in yellow, white, and black, with a pair of black tentacles on both ends of their bodies. The photo below shows a caterpillar that is next to a molted skin. Monarch caterpillars will grow to about 2,000 times their original size!
If you have followed all the signs, then you will find monarchs! Good luck!
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!

10 Butterflies That You May Have Seen Before
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!
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.

Spring is a great time to transplant milkweed plants! Milkweed has a deep taproot and it is best to transplant when the plant is small and the tap root is not as deep. If you cut off too much of the taproot then it is not likely to succeed.
1. It is best to transplant milkweed in the spring when the plant is small. Transplant on a day that is cloudy or during the cooler morning/evening hours. This will make it less stressful on the plant.
Gardening has long been considered therapeutic for people experiencing stress or mental health issues. In the late eighteenth century, Dr. Benjamin Rush, who was considered to be the first psychiatrist, reported beneficial effects of horticulture for people with mental health difficulties. There has been a recent revival of nature-based health solutions as our world becomes more urbanized.
Improving Physical Health
Gardening helps you meet physical activity recommendations that make you healthier and happier!
According to a 2017 study published by the Sustainability academic journal, gardening tasks that use both the upper and lower body meet the physical activity recommendations from the CDC and American College of Sport Medicine for moderate-intensity physical activity for older adults. Furthermore, results from the Short-Form 36 health survey showed that gardening can promote hand strength, pinch force, and overall physical health.
Reducing Stress and Providing Therapy
Did you know that fascination for your garden can actually be a restorative practice?
According to Kaplan (1989), directed attention is a limited resource that can be overloaded (causing stress) and that people need to use the alternative system, fascination, to restore it. Fascination is thought to be dominant in natural environments, such as gardens, where there are captivating stimuli to hold attention.
Nature is intrinsically healing. Simply looking out your window at nature can boost your sense of well-being! So get out there are plant those beautiful flowers so you can view beautiful butterflies fluttering outside your window as well.
According to research by Kaplan (2001), viewing plants and a garden through your window contributes to a feeling of well-being and satisfaction. Another study demonstrated that being able to observe nature – through view of trees from their hospital bed – had physiological and psychological healing benefits for patients recovering from surgery when compared to patients who had a view of a brick building wall (Ulrich, 1984)
Improving Memory and Cognition
Stress can actually decrease one's ability to remember things and problem solve.
According to a recent study, the restorative quality of gardens can improve cognition, memory and problem solving abilities! (Adhemar).
Eating vegetables straight from your garden are known to increase your immune system as your body receives all those nutrients!
Brightly-colored vegetables have been noted to increase interleukin-2, a substance responsible for promoting white cell function in the immune system (Gibson, 2012).
Promoting Mental Health and Reducing Stress
There are numerous scientific studies that have concluded that gardening can have a myriad of psychological benefits such as: reducing stress, anxiety, and depression.
An article by Ulrich (1991) concludes that exposure to natural environments is one of the most important factors to stress recovery. Close contact with nature yields numerous psychological and physiological benefits, ranging from increased pain tolerance, recovery from stress and anxiety through to relaxation and enhanced wellbeing (Clatworthy, 2012). Domestic gardens provide regular access to sunshine and fresh air, which regulate circadian rhythms that control sleeping and eating patterns.

In honor of Arbor Day coming up on April 24th, we thought we would talk about some of the top butterfly-supporting trees! The trees we have chosen wear multiple hats, so to speak. These trees will support more than one species of caterpillar in its development to becoming a full-fledged butterfly!
Oak (Quercus spp.)
Sweetbay Magnolia (Magnolia virginiana )
Hackberry (Celtis occidentalis)
Serviceberry (Amelanchier arborea)
Paw Paw (Asimina triloba)
Monarchs very rarely pupate on the host plant that they hatched on. In fact, they can pupate up to 10 meters away from their original host milkweed! They look for places to pupate where they will be safe from predators and inclement weather but sometimes they don't always choose the most logical locations. Here is a list of places to look for chrysalises.
Why would I want to move a chrysalis?
1) It has fallen to the ground.
Monarch chrysalises can get dislodged by wind, rain, birds, people and several other factors! In order for a Monarch to eclose safely, the chrysalis needs to be suspended in the air. The Monarchs often cling to their empty chrysalis as they uncrumple their wings and air dry them before being able to take flight. If they do not have sufficient space ( at least 1-2 inches on all sides and 4 inches below), their wings may not develop correctly and they won't be able to fly.
2) It's in harm's way.
Have you ever found a chrysalis in a doorway, on a car tire, on a window or somewhere you know it is unsafe? You may want to relocate the chrysalis to a safer location.
3) You want to watch the metamorphosis occur.
It's okay if you want to move the chrysalis into a protected area such as a butterfly house or mesh enclosure in order to watch the beautiful process occur. Experts say that less than 10% of wild Monarchs survive outdoors due to predation. Monarchs make up for this low rate of survival by laying 300-500 eggs in their lifetimes. Watching this miracle occur is a joy for all ages and can be a wonderful educational tool for children.
How to Move a Monarch Chrysalis
- Dental Floss
- A Pin or Safety Pin
Step 1: Locate the Chrysalis and Make Sure It is Safe to Move
Fresh chrysalises are delicate and need time to harden before you can move them safely. Observe the chrysalis before moving it. Is it an opaque green or is it starting to turn transparent so you can see the Monarch inside?
The Monarch's pupation stage is 10-14 days and the chrysalis will harden after 1-2 days. If the chrysalis is completely transparent, revealing the black and orange butterfly within, it will begin to emerge within 24 hours. If you are unsure when pupation occured, it is best to wait a day before moving the chrysalis.
However, If you know that it is in dire danger, then move immediately with the utmost care. If a chrysalis breaks, it will ooze and the Monarch will not be able to survive this damage.
Step 2: Remove the Silk Pad
Look closely at the chrysalis and use a magnifying glass if necessary. The silk pad will be attached to the surface and the black cremaster is directly below it. Very gently, loosen the silk pad by inserted the pin where the surface and silk meet. Try not to disturb the cremaster. Carefully, wiggle the pin until the silk starts to pull away from the surface. Once there is enough slack, pull the silk off of the surface with your fingers or tweezers if needed. Cup your other hand beneath the chrysalis to protect it from falling to the ground.
Step 3: Adhere Dental Floss to the Silk Pad
Step 4: Hang the Beautiful Chrysalis
Grab the ends of the floss and tie around a branch, rod or other secure fixture that is at least 4 inches off of the ground and 1 inches of clearance on all sides. If you are using a mesh enclosure instead, use the pin to secure the knot to the top of the cage.
Step 5: Let the Butterfly Hang Out!
It takes several hours for the monarch butterfly's wings to dry properly. They may begin to flap them gently to expedite the process. Let them be and do not touch their wings at all while they are drying. This can damage the scales on them and render them unable to fly.
Congratulations!! You just successfully moved a chrysalis and may have just save their lives!
🦋Provide a water source such as a bird bath, shallow dish, fountain or pond. Butterflies prefer shallow water!

Symbolic Monarch Migration
Every year Journey North sends a flock of Monarch symbolic butterflies in the mail to schools in Mexico and they return in the Spring.
"Join students across the globe to create symbolic monarch butterflies to send to Mexico. Children who live beside the monarchs’ winter sanctuaries in Mexico will protect the paper butterflies and return them in the spring. Through the Symbolic Migration, children are united by the monarch butterfly and celebrate its spectacular migration. They learn authentic lessons of conservation and international cooperation."

Although many of us are spending more time at home due to the health crisis, there are still many ways you can support the monarchs without leaving your backyard. Now is the perfect time to start brainstorming your beautiful butterfly garden, planting milkweed and collecting data to help with citizen science projects!
1. Plant Pollinator Habitat Wherever You Can
2. Teach Children About Monarch Conservation
3. Rear Monarchs from Home
4. Start Your Milkweed Indoors
5. Participate in a Citizen Science Projects
Becoming a citizen scientist is fun and allows you to virtually connect with other nature enthusiasts, naturalists and conservationists. Citizen scientists from around the country log data and observations which is vital to understanding the monarch migration, biological cycles and why they are disappearing.
6. Support Organizations Working to Sustain Monarchs
Make a donation to your favorite monarch or pollinator conservation program. Many programs are donation-based and are fighting to save our monarchs.
7. Conduct Your Own Research
The monarchs have begun to leave their overwintering grounds in Mexico and are heading North! Starting milkweed seeds indoors is a great way to ensure you will have milkweed plants ready for them when they arrive.
