Monarch Health

Monarch Health Monarch Health: A community science project where volunteers across North America monitor the health of wild monarchs.

We collaborate with participants to track the spread of the parasite Ophryocystis elektroscirrha over geographic space and through time. Monarch Health is a community science project to track the prevalence of the protozoan parasite Ophryocystis elektroscirrha (OE) in monarch butterflies. This parasite does not infect humans but can make butterflies sick: Monarchs infected with OE often do not fly as well or live as long as uninfected monarchs. Infected monarchs may look deformed after they emerge from their chrysalis, or they may appear completely normal. To test monarchs for OE infection, volunteer participants (1) Obtain wild adult monarchs by either catching or rearing them, and (2) Press a clear sticker against the monarchs' abdomen to collect any parasites (which are external at this stage). Monarchs are then released, entirely unharmed. At the Altizer lab at the University of Georgia, we examine each sample using a microscope to detect OE parasites. We share all results with participants, answer questions about monarch diseases, and send free sampling kits to volunteers.

📣Calling all monarch butterfly enthusiasts— the GA DNR needs your help!📣

Monarch sightings during the winter can determine if the species can overwinter as non-breeding adults in the southern U.S. and how this might affect future population numbers.

Understanding migration and overwintering behavior is crucial to conserving monarchs, who are up for a spot on the Endangered Species list.

Thousands of monarch butterflies fly South each fall to overwinter in central Mexico— but not all monarchs.

If you spot a monarch in any stage (adult, egg, larval, and pupal) from November to March in the Southeast United States, please report it through Journey North or iNaturalist.🚨🦋

Want to track a monarch? 🦋

Well now you can thanks to ultra-light transmitters developed by Cellular Tracking Technologies!
This incredible new technology will help researchers better understand monarch migration and conservation. Monarch tracking isn’t just for researchers, either. You can download the Project Monarch Science app on your smartphone too! 📲📍

Monarchs make the New York Times....

We’re excited to share that the New York Times published an article today about the Project Monarch Collaboration’s efforts to track monarchs this fall using novel technology. Find the link to the article in the comments section of this post.

Founded through a partnership between Cellular Tracking Technologies and the Cape May Point Arts and Science Center, the Project Monarch Collaboration involves the amazing efforts of lots of conservation organizations and scientists to deploy BlūMorpho radio tags on monarchs during the fall migration this year. We're grateful that Monarch Watch could be a participant.

This groundbreaking project paves the way for new opportunities to study the monarch migration. We’ll be sharing more this week about the monarchs that we tagged, so stay tuned!

Over 20 partner organizations, including the Monarch Joint Venture, came together to deploy over 400 transmitters on migrating monarchs during fall 2025 for Project Monarch, a collaborative effort founded by Cellular Tracking Technologies and the Cape May Point Arts & Science Center.

The project has shattered previous limitations in butterfly tracking, providing scientists with high-resolution, near-real-time data on individual butterflies as they navigate their incredible fall journey.

Tagged monarchs have been tracked from the Rocky Mountains to the East Coast on their travels down to Florida, Mexico, and the Caribbean. As of Nov. 9, some tagged monarchs started reaching overwintering areas in Mexico.

Take a look at the map of this year's tagged monarchs here, or download the Project Monarch app to view individual monarchs' migration routes.

🦋 We're excited to share the results of volunteer-based monitoring efforts from 2024! 🦋
In the attached newsletter, you may read more about highlights such as:
🐛 Where was OE infection prevalence highest in 2024? Over 60% of samples we received from the South were infected. Meanwhile, the Central US had the least infection prevalence, with a little over 20% of samples heavily infected with OE.
🦋 PMH trends: in the past 10 years, how have infection prevalence and the amount of samples received by PMH changed? We summarize a decade of citizen science data.
🔬 What's the host range of OE? A study published by a recent PhD graduate from the Altizer lab, where our project is based, tracked parasite infections across six continents.
We would like to thank Sydney Weigand at UGA for helping us develop this newsletter. We also thank our volunteers for dedicating their time and effort to helping us spread scientific knowledge on monarch ecology and conservation. We wouldn't have these results without your dedication and support! 👏

Meet one of the organizations that volunteers with us!! 🦋

Cambridge Butterfly Conservatory is a privately owned tourist attraction in Cambridge, Ontario, featuring a lush tropical garden filled with thousands of free-flying butterflies, exotic birds, and tropical plants. They combine science education with wonder —offering engaging exhibits, live insect displays, and a unique Emergence Window where visitors can watch butterflies take their first flight. Guided by a commitment to education, conservation, and research, the Conservatory provides interactive programs for schools, families, and community groups, while inviting all visitors to connect with the beauty and importance of the natural world.

Cambridge Butterfly Conservatory began incorporating Project Monarch Health into their annual Monarch Tagging event several years ago. Most of their PMH samples come from this event, which is held during one of the first couple weekends in September.

“We demonstrate and educate about the tagging through Monarch Watch, as well as about the spread of OE and Project Monarch Health. In this way we’re both contributing to citizen/community science, while educating others and also showing them the importance of contributing to these projects,” says Andalyne Tofflemire, the Conservatory's naturalist.

This month, they have featured the local Woolly Bear caterpillar and how insects overwinter! Although butterflies are their main focus, they like to include moths as much as possible since they are a keystone invertebrate in many ecosystems.

Their team consists of a variety of departments including administrative, guest services, educators & nature interpreters, cafe and wedding staff.

“A lot of us have varying backgrounds in wildlife biology, outdoor education, environmental science and museum studies just to name a few. We generally are all nature-loving folks into bugs, birds and all kinds of critters, passionate about conservation and education.”

Outside of Project Monarch Health, Cambridge Butterfly Conservatory is proud to have been involved with conservation efforts for the endangered Mottled Duskywing (Erynnis martialis) over the last 5+ years. As part of the Ontario Butterfly Species At Risk Recovery Team, they were an integral part of the first successful reintroduction of a butterfly in Ontario! The next species their team plans to work with is the endangered Frosted Elfin (Callophrys irus).

Want to get involved? Here’s what’s coming up:

FEBRUARY: Visit them on Family Day to meet live animals in their Critter Corner!

MARCH: During March break, join them for their Magical Morpho event featuring thousands of Blue Morpho butterflies and others!

“We are glad to help get the word out. It’s an important conservation message that people’s actions in their own backyards have significant effects on our wildlife.”

Thank you Cambridge Butterfly Conservatory for supporting our project! 🐛

Meet Project Monarch Health's Director!🦋

Sonia is a UGA Distinguished Research Professor and serves as Department Head for Entomology at the University of Georgia. Her research focuses on insect ecology, animal migration, parasites and environmental change. For the past 30 years, starting as a PhD student at the University of Minnesota, she’s studied the migration, ecology and conservation of monarch butterflies. Sonia launched Project Monarch Health at UGA in 2006 with the help of then-undergraduate student Natalie Kolleda-Tarpein. When she is not chasing butterflies or working in the office, lab or classroom, Sonia is trail riding with her two horses, walking her golden retriever, picking veggies in the garden, and hanging out with her two boys, ages 10 and 14. Fun fact: This year, Sonia added amateur beekeeper to her list of hobbies! 🐛
