How to Safely Move & Hang a Monarch Butterfly Chrysalis

Monarchs are such magical creatures! Their quick transformation from adorable chubby caterpillars into goo-filled jeweled chrysalids, and finally magnificent butterflies, is nothing short of mind-blowing. But just because monarchs are magical doesn’t mean they are particularly invincible, or all that logical when it comes to where they decide to form their chrysalis. Sometimes, we may need to step in and help – and move a monarch chrysalis to protect it from impending doom!

There may be times in your journey of raising monarchs, or simply when you find them in your garden, that you may want to assist with relocating or hanging a chrysalis. Come read along to see why and how to safely do this! If you are feeling nervous about it, hopefully the photos and videos below will help ease those worries. It is a delicate process, but very simple to do!

Why is chrysalis spacing important?

As you likely already realize, it is absolutely essential for a monarch to hang upside down from their chrysalis immediately after emerging as a butterfly. The moment they emerge is also called “eclose”.  After eclosing, the act of hanging upside down enables their fresh, crumpled wings to fill with fluid, straighten, and dry. Most often, a monarch will cling to its now-empty chrysalis casing to hang. Sometimes they will wander onto a nearby surface to hang as well.

If a monarch doesn’t have adequate space or the ability to hang to dry, their wings will not form correctly. More likely than not, they will be unable to fly. Unless you intend on hand-rearing a flightless butterfly in a cage, this means certain death for them. When relocating them, provide at least 1 to 2 inches around the sides of their chrysalis, and about 4 inches of space below.

When to move a monarch chrysalis?

One instance you’ll want to intervene is when a formed chrysalis falls (and miraculously doesn’t break!), and thus needs to be hung back up. Or, you may want to move a monarch chrysalis when a silly caterpillar chooses to make its chrysalis in a less-than-ideal location. We have had many caterpillars hang from the bottom of an aging leaf that is going to fall from the plant soon. Not the best idea, guys. Some of ours like to cram themselves up against the enclosure door or zipper, which is also precarious. I move those ones too.

Many people who raise monarchs move their formed chrysalids into a designated enclosure to elcose in. For biosecurity and sanitation, it is best practice to not have fresh butterflies emerge over the majority of the caterpillar population. The largest concern is sloughing of OE spores, a protozoan parasite that affects monarchs. I also relocate any chrysalids that look unhealthy to me, for example, with an off color or form. If I suspect they may have disease or parasites, I move them to a separate space (usually outdoors) away from the rest of the babes.

These two definitely needed a new spot! The chrysalis on the left was found on our avocado tree. Avocados are notorious for frequently shedding leaves! And the one on the right decided to do her thang on the zipper of their tent.

In the example photos below, you’ll see a monarch caterpillar that chose a pretty sturdy spot on a milkweed stem to form a chrysalis. It probably would have emerged just fine there! However, it was time to rotate that munched plant out of the monarch enclosure. Therefore, that chrysalis needed to be carefully removed and relocated.

How to Move a Monarch Chrysalis

Supplies needed:

  • A pin, needle, or safety pin. I like to use a ball point sewing pin, as shown below.
  • Dental floss or thread
  • Small scissors

Step 1: Wait until the Chrysalis Hardens

First things first: Do not attempt to move a monarch chrysalis that has not completely hardened yet. After the caterpillar transforms into a chrysalis, it usually takes about 1 to 2 days to fully dry and harden. If you move it before then, you run the risk of breaking or damaging it, especially if you accidentally jostle it in the process. When a chrysalis breaks, cracks, or otherwise starts oozing liquid, it is game over.

If you find a chrysalis and aren’t sure when it first formed, wait another day to move it – if it seems safe to wait, that is! When they need immediate assistance (i.e. tachinid flies are swarming, or it is about to fall) then do what is necessary regardless of time. Just be extra gentle.

Also note that a monarch chrysalis will turn from green to dark grey to black, and finally become totally transparent (revealing the black and orange wings inside) before a monarch butterfly emerges. So, if the chrysalis in question is still green, know that you still have at least a couple days to move it before the butterfly is coming and needs to hang!

Step 2: Loosen the silk pad

Examine where the top of the chrysalis meets whatever surface it is attached to. Often times, it will look like only the small black tip of the chrysalis (called the cremaster) is what is holding on. In reality, the caterpillar has spun a large perimeter of silk material around the spot from which it hangs, called the silk pad. The silk pad may be as small as a dime, or as expansive as silver-dollar and beyond. They attach their hind end to a thick part of silk in the center, called the silk button.

To loosen their silk pad, I gently insert a pin between their cremaster or other visible silk and the surface it’s attached to. Carefully pull and wiggle to loosen the silk from the surface. It will usually stay in one piece, attached to the cremaster. Continue to loosen the silk until there is enough slack to pinch and grasp the silk and cremaster. Gently pull it all away, detaching the chrysalis and silk from the surface it was on. You can use your fingers, or tweezers if needed. Cup your free hand under the chrysalis in case it falls.

Once you have the chrysalis in hand, set it somewhere safe and secure to continue the next steps. They are slippery and light! If it is windy, the chrysalis may blow around. Consider setting it on a washcloth or something to help hold it in place.

Next, a hand is using a sewing pin to loosen the silk at the end of the chrysalis, until it is free and being held, no longer attached tot the branch.

Step 3: Create a new faux “silk” to hang it

Next, we need to tie something around the very top of the chrysalis to re-hang it with. I know some people simply stick a safety pin through the excess remaining silk and hang them that way. However, I have seen pins rip through silk, so I prefer to do something a tad more secure.

Waxed dental floss is a wonderful material to hang a chrysalis, because it is thick and sort of sticky. Knots made with waxed floss will not slip! Thread can be used as well, but may not be quite as sturdy or easy to work with.

  • Cut a piece of floss about 4 to 6 inches long, depending on what you plan to hang the chrysalis from.
  • Tie a loose knot in the center of the floss to create a small loop. Do not pull it tight yet.
  • Slip the little loop over the silk and black tip of the chrysalis – the cremaster.
  • If there is a large amount of silk, I will often cut it down to a shorter nub (but not all the way off!) before slipping the loop over. Otherwise, it tends to get in my way. You definitely want some left behind though, or it is too easy for the floss to slip right off the top of the cremaster.
  • Finally, pull your knot tight around the cremaster, or the area where the cremaster and silk meet. I usually make a double-knot.
  • If you ever encounter a chrysalis that is missing all the silk, it is okay to put a tiny dab of glue on the cremaster where you tie the floss. This will help it from slipping off.

Step 4: Hang your jewel

Using the loose ends of the floss, I tie the chrysalis around one of the small secure branches in our largest monarch enclosure. This enclosure is designated for eclosing butterflies and only the biggest, about-to-hang cats. It is okay if you don’t have something to tie the floss around per se! If you are using a mesh butterfly tent, simply tie the floss in a loop and pin it to the roof of the tent with a safety pin instead.

The chrysalis doesn’t necessarily need to be super tight against something. Monarch butterflies do usually hold on to the chrysalis itself when they emerge and hang to dry… However, I have seen a few start to slip from their chrysalis and instead crawl onto the nearby stick or mesh surface to get a better grip. Thus, that could be an instance when having a large loop of free-hanging floss (not tight against another surface) could be a disadvantage. They don’t have much else to grasp onto in that case.

After Eclosing

Remember, let that baby hang! It can take several hours for a monarch butterfly to dry, even if their wings look fully expanded. In an enclosure, they’ll usually start flapping around a bit when they’re ready to get out and fly. I gently transfer them on my fingers from the enclosure to a nectar-producing flower in our yard, hanging them upside down from the flower as well.

If a monarch slips from its chrysalis or surface while it is still wet, immediately assist it to re-hang and properly dry. If they seem too weak to hang on, continually slipping, it is possible they have a disease such as OE, other parasites, or virus. Let’s hope you won’t have to deal with that too much.

I hope this post makes you feel more confident to help your little friends out and move a monarch chrysalis when they’re in need! Trust me, I was nervous when I did this for the first time too. You’ll get the hang of it! Just be gentle and treat them like the precious jewels they are. And don’t accidentally poke them with the pin!

I should note that there are a few other ways I have seen folks hang and move a chrysalis. Some even use glue! This is simply the way we have found most efficient and effective. Please let me know if you have any questions, and spread the monarch love by sharing this article with friends.

    Thank you for the wonderful info! One of our caterpillars has chosen the side of our enclosure to form its chrysalis and I’m worried that when the butterfly won’t have room there to safely emerge. Is it safe to move the hanging caterpillar or should we wait until it forms its chrysalis and hardens?

    • Aaron (Mr. DeannaCat)

      Hi Emily, it is best to wait until it has formed into a hardened chrysalis before you move it. Good luck!

    • Aaron (Mr. DeannaCat)

      Hi Donna, yes it is best to move the chrysalis from a dying leaf as the leaf will likely fall off before the butterfly emerges.

  • Debbie

    Hi . I noticed iin the pictures above the top of your enclosure is screened but in the other article it has a wood ceiling? We built one with a wood celinging and Im wondering if they are getting enought light…had a couple turn dark and nothing emerged 🙁 how do you protect them from rheavy rains with a screened top ?

    • Aaron (Mr. DeannaCat)

      Hi Debbie, we place a piece of plywood on top to protect them from rain and hot direct sun. The chrysalids could have been infected with tachinid flies or any of another issues that they face, it isn’t 100% success rate by any means.

  • Meaghan

    This is such great info! We are raising monarchs for the first time and one of ours attached to a wilting leaf. We were quite worried about how it would fare, but now we know we can help it out!!

  • Elle

    Bless you! I cannot give you enough praise and thanks for your outstanding posts!

    I just began raising (hopefully) monarchs two weeks ago. Could not be happier! I bought many milkweed plants of various sizes and have near 2 dozen cats stages 1-4. And more eggs! I have researched exhaustively to learn all I can. Difficult to find a fully comprehensive site.
    Until I found yours! Extremely well written in concise, comprehensive detail from egg to butterfly. Your clear details along with excellent quality photos completely filled the gaps of missing information I needed and to reinforce the plan I just started- moving tiny newly hatched, cat 1 and 2’s to their own plant for safety and moving the adol’s & teens to bushier milkweed plants. And critical is the reference to heat! CA is forecast to be in the 100’s in several days. May need to move my brood indoors.

    Perfect timing to find you. I have 4 cats ready to molt to stage 5. I bought a cage and hope it will work. I want the rig you have but not sure I could build that myself.

    Much appreciation and gratitude to you for your devotion and passion to an important part of nature’s ecology.

    • Aaron (Mr. DeannaCat)

      Thank you so much Elle, we are glad you found our site and good luck with your Monarch rearing efforts!

  • Nancy

    Help! my caterpillar is spinning it’s silk girdle and attaching itself to the zipper of it’s enclosure. It has chosen the very beginning of the zipper and I am worried that I might cause damage if I try to open it. I don’t want my other caterpillars to starve…should I cut the mesh open?

    • Aaron (Mr. DeannaCat)

      Hi Nancy, unfortunately this happens more than you would think! First, before you do anything make sure the caterpillar has time to transform into a chrysalis if possible. Once it has hardened fully (usually takes a couple days) see if there is any way possible to open the zipper even the slightest amount to access the chrysalis within. If the silk is the only part of it that is in the zippers path, you may be able to open more than you would think allowing you to move the chrysalis to a safer location. If things are tight, you could poke a sewing needle through the mesh and try and separate the silk from the zipper without even having to open the enclosure. You will probably just have to try a couple things and see what works best for the situation, hope that helps and good luck!

  • AngelinaC

    Thank you!! Found red spider mites on the plant two had crysalized (new word!) and needed to move. One did on the edge of a pot…

    Now they’re safely hanging til I can find a good stick.

    Looks like spider mites are on a crysalis in that enclosure, damaging it. 😟

    But we’re better off for this article! Thanks!

  • Karen Bruns

    Thank you soooooooo much for being online. I just found you this morning. I was surprised to find a chrysalis hanging from a rock 4″ off the ground. So now I will do my best to move this one carefully to a safer place, thanks to your advice. Usually I find them safely hanging from my black-eyed Susan vine 4 or 5 ft off the ground in the planting bed. But you’re right…I think they do need our intervening help sometimes. Many times they eat rapidly through the few milkweed plants I have around my mobile home. Then suddenly I have to go buy more plants. I have some milkweed growing in the City’s (Hermosa Beach, CA) greenbelt across the street so that’s really been a lifesaver. I found a very old dried chrysalis hanging from a jade plant this morning. Glad to know that’s also a good source for “hanging” as jade plants tend to be drought tolerant and that’s what is really preferred in Southern CA. 3-1-21

    Thank you so much for posting this article! I just recently got into raising and releasing monarch butterflies and I’m very nervous all the time that I’m doing something wrong or I’m somehow going to hurt them. You’ve given me a bit of confidence going forward that, as long as I’m gentle, everything should be okay.

    I love your enclosure and was wondering if you may be have directions on how to build one that would be similar if not identical to yours. Right now I have the pop-up mesh enclosures and they are great while the butterflies are munching away but I’ve noticed that when it comes time to release any butterflies it’s a bit difficult. The butterflies get mixed in with the taller plants at the base of the enclosure or on a side branch of a milkweed and they are very difficult to get to. Your setup on the other hand makes great sense and I would love to be able to move any chrysalis to an enclosure like yours so I can continue having baby caterpillars in the mesh and closures.

    Again, many thanks. You’ve given me much more confidence when it comes to dealing with the chrysalis. On a side note we have one emerging right now.I’ve never caught one at the beginning of its emergence so this is very exciting for me.

    And your experience, how many hours do the newly emerged butterflies need to dry before release?

  • Jackie

    Thanks for this write up! First time with monarchs in my patio and most of them seemed to have found a safe space under the patio ledge, but I have one that’s on the side of a pot. Will the side of the pot affect the monarch’s wing drying process? When fall/mild winter time comes along, should I be concerned about storms or strong winds?

    • Aaron (Mr. DeannaCat)

      Hello Jackie, Monarch caterpillars find some tight spots to create their chrysalis. It may be just fine once it emerges but you could always move the chrysalis and place it in a more open space, we have an article here if your interested: How to Safely Move & Hang a Monarch Butterfly Chrysalis. In regards to your weather and the Monarch butterflies, they should be just fine as long as they are allowed to properly hang and dry once they emerge. When it is time for them to fly, they’re on their own and will adapt to whatever conditions are present. Thanks and good luck!

      • Mandi Lynn

        Thank you! You information is very detailed and explained just right! I knew this lil guy was in a horrible, vulnerable spot but I didn’t know what could be done; put a tent around him or build a lil house like structure. He/ she had decided to hang from the antique rusted wagon wheel in the front of the house; susceptible to every possible danger! If there is the slightest breeze or passing prey he’s a goner!!! What should I do to protect him until he can be moved?

        • Aaron (Mr. DeannaCat)

          Hi Mandi, once they spin their silk and hang from it, it’s actually quite strong so even a heavy wind shouldn’t knock it free. It should be fine if you leave it until it forms its chrysalis which shouldn’t be too far off. Good luck!
