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.

    Hi, your articles are the best I have seen, by far! Excellent work, and much appreciated. I don’t subscribe to much, but I couldn’t sign up for yours fast enough. Keep going!

  • Angela

    Hi! I have learned so much from your blog, so much that I decided to raise some myself. We had over 30 butterflies hatch and survive! But I have a question about moving the chrysalis, what if it breaks off of the silk; how do you remedy this? Thank you!

    • admin

      As long as the chrysalis is still in tact and okay – just tie floss around the cremaster, and you can add a tiny drop of glue within the floss/knot if needed for extra support. We had needed to do this for a few slippery ones that didn’t want to stay on just the cremaster itself!

      • Sarah

        Thank you so much for this! I have always wanted a butterfly garden and we have bought a ton of topical milkweed here in zone eight. We are running a monarch daycare but a few chrysalis have needed to be moved. I really appreciate this article! Do you have another article which shows how you build your enclosure? I would love to get strategies on how big he made it, what materials you use, and that sort of thing. We appreciate you so much!

        • DeannaCat

          Hi Sarah! Yes, in our “all about raising monarchs” article (see that here) we show our enclosure and go over the dimensions/how we made it as well. Happy spring, and thanks for helping our monarch friends!

  • Mechelle Brachel

    I was watching my cat change while it was on the ground. After it changed I worried about it being on the ground and read about the floss so I did that right away, it was only about 15 minutes after it changed. While I was tying the floss around the cremaster, the chrysalis moved like I was hurting him. I hung him on the top of the cage and he seems okay, no oozing, or cracking or anything. Did I hurt it by doing it before it was hard?

    • DeannaCat

      No, it sounds like you did a good job! I just suggest waiting when possible only because it is so easy to accidentally crack them at that stage (I have done it myself…) and it’s pretty sad when that happens. But you were gentle and it should be fine! Good job 😉

  • Lori

    This is my first time trying to raise monarchs. I have 9 and just found a tiny caterpillar today that must have been an egg on one of the leaves. One of the first ones to make a chrysalis hatched today. Amazing! What fun, can’t wait to share this process with my granddaughter!

  • Tracy

    Thank you thank you thank you for posting this! It’s a great step by step explanation that was much needed! (For me anyway!)

  • MarcoPug

    Great info! I have been hesitant to move them, but now after reading this, it seems like a simple, delicate process. We bought a milkweed plant a couple of years ago and my kids LOVE watching the whole process! We named one of the monarch’s Monty, so now whenever a monarch comes swooping around our garden, the kids yell oh Monty’s here! Thanks again for passing down the wisdom!

  • Holly

    This looks so rewarding. I learned a bunch of stuff I really didn’t know.
    When my girls were little if we found a monarch caterpillar, we would keep them in hopes of watching their journey. It was really a lot of fun.

  • Christina Lauren

    Thanks so much for sharing! 🧡 I had a Monarch go into chrysalis on a section of my dog fence last year and it made me a nervous wreck. This year I’ll be ready for whatever pesky places the caterpillars come up with 😁

  • Jenna Ali

    I’ve had the problem of the floss slicing right through the cremaster as I tightened the knot before and I had to rig something up with super glue! It was so stressful! Now I try not to move them if at all possible but there’s one on the jamb of my side garage door that will get squished if the door is fully opened so I know I have to get on it soon. I’m sweating it, though!

    • DeannaCat

      Crazy! You must have had been working with sharp floss, a hard pull, or a thin cremaster! I have never had that happen. Try tying it higher, right near the silk, or even to the silk itself if you’re worried. Our floss is that wide flat stuff, so maybe it makes it harder to “slice”? I tie a knot, but not crazy tight tho… Im’ sure you’ll be fine!

  • Emily

    After a caterpillar has been moved, I imagine them like a college student waking up, not quite remembering where they fell asleep 😆

      • Valerie Cavagnaro

        I have a ton of caterpillars this year. I just found a crystlis on one of our lawn chairs. Its on the back of the chair but its on the front of the back. So I have to move it or it will get squished. Your site is very informative. Thank you.
