Why are monarch butterflies disappearing? You may know them for their amazing transcontinental migration, but over the past few decades, monarch butterflies have been part of a vanishing act that has scientists worried. Conservation biologists Ashley Fisher and Isis Howard show us what it takes to track monarch butterfly populations at one of their favorite overwintering spots.
Join our host and museum curator Jessica Ware, Ph.D. for a close look at this iconic insect, its incredible lifecycle, and its multigenerational migration. Then, follow scientists who are working at a monarch butterfly roosting site in the western U.S. to figure out what’s behind the monarch butterfly population plunge. The series is produced for PBS by the American Museum of Natural History.

I'm sorry, you said only TWO THOUSAND were left?! They were that close to extinction? Crazy
Blame DuPont for RoundUp. They convinced the farmers to use it everywhere. Now they're getting all the highway departments to use it too. It's very very hard to find any wildflowers in agricultural areas. We're starving them, and not just monarchs.😢
my 3rd grade class had two "pet" monarchs. The teacher found a few caterpillars outside, put them in a little habitat that was regularly stocked with fresh milkweed from where they were found, and we watched them grow into the chrysalis stage. Two butterflies, a male and a female emerged, and we all submitted names to then vote on. The kids ended up choosing my submission for both sexes separately - Superman and Wonder Woman, lol. Once they finished priming their wings, we released them outside behind the school. One landed on my shoulder before departure. That was 25 years ago, and a beautiful experience that I wish today's children could have. To see such a fragile little thing of beauty fly into the sky and know it was probably going to fly to Mexico...all the way from New Jersey.
Seeing a swarm of monarchs is one of the most magical experiences. I had the pleasure of witnessing a migration starting when I was a kid in Michigan - absolutely a core memory
shoutout to the butterflies who have to lift heavy and fly with antennas in the name of research. many more butterflies will be born and will fly free thanks to you. your efforts and contributions will not be forgotten
I live in Southern ontario and recently started planting milkweed and goldenrod in our backyard to help native birds and bugs, hoping more people will start doing the same
I once saw a Monarch butterfly in the Canary Islands. They've likely been blown over on Atlantic storms but there's a breading population now!
If you ever get the opportunity to be up near Pismo Beach, CA in the winter, don't pass up the chance to visit the Monarch Grove. The Eucalyptus trees are absolutely covered with butterflies. It is an amazing sight and the way things are going, you may never get another chance in the future.
I remember in kindergarten we had a bunch of caterpillars in boxes in the back of the classroom and then we took them outside when they all emerged from their cocoons and the school yard was filled with monarch butterflies.
Here in Virginia we have common milkweed, which spreads underground, and can provide a lot of habitat quickly. Swamp milkweed is good for wet areas, but also can be grown in places other than swamps. Butterfly milkweed is well behaved and shorter in stature than both of the other two species. These are the three most common species I see here in the mountains of Virginia.
I had the good fortune of having a monarch butterfly hatch out a chrysalis in my tomato garden. I even got to watch the hatching live. Absolutely amazing creatures.
I'm in iowa and I always feel bad for all the butterflies that get hit by cars and trucks on the highway
The big monarch migration hit while I was at CSUDH. The campus was completely covered with traveling monarchs and some professors even let us leave class to see them at the daily height!
Last year was the first year I had seen Monarchs in our area in years... sadly there were only about 3 or 4 seen around my house.
I live in WA State, and have always enjoyed seeing the Monarchs every summer. I saw ONE last year. It's incredibly sad.
Here in Pennsylvania there are thousands of miles of roads that are clipped, mowed and chemically treated to look like manicured lawns. In earlier years these areas and medians were filled with native flowering plants, especially the species of milkweed that Monarch caterpillars preferred and where adult Monarchs layed their eggs. There is no reason why huge areas can't be planted with milkweed and other native plants using the money that is now being spent on mowing etc. Taking this cost effective step would have a major impact in helping the Monarch population to grow significantly while saving the taxpayers significant amounts of money as well. If other states would do the same, Monarch numbers would explode in a few short years.
I remember participating in the eastern butterfly count in my area once 20 some years ago.

As kids we hiked up this gravel pile, (laid down during the Last Ice Age) in the middle of the Susquehanna Valley back in the 60"s. Otego NY. There was a migration of Monarch butterflies heading south. Regular "river or carpet" that skimmed the peak of that gravel pile. Stretched for miles. Me and my brothers along with some cousins were in the middle of a "Blizzard" of them for the next say half hour. From time to time would see them still head both North and South.
This video is awesome! I visited the Butterfly Vivarium at the AMNH with my family at the Glider Center in April 2023 and Summer 2023 and it was awesome! It had all my favorite butterfly species from the monarch butterflies, tiger swallowtail butterflies and painted lady butterflies of North America to the blue morpho butterflies, Queen Alexandaria’s birdwing butterflies and postman butterflies of South America. I also loved the live chrysalises/pupas it kept too for the butterflies to emerge from. But I wish it had live caterpillars/larvae for all the butterfly species from the vivarium as well, including the ones I just mentioned eating their host plants (Including milkweed and parsley and thistle plants for monarch, swallowtail and painted lady caterpillars and before becoming chrysalises to become the adults. The downstairs Insect Lab does have some silkworms however eating mulberry leaves before some of them changed into pupas and became silk cocoons which will be moved to the tent where the atlas moths live in the Butterfly Vivarium where the domestic silk moths will emerge from their cocoons and live there too.
