The Butterfly Effect
How one education alumna is spreading her wings and sharing her passion for nature one butterfly at a time

In the rugged mountains of central Mexico, Peggy Campbell-Rush boarded an open pickup truck, rode on horseback, and hiked with a small group led by an internationally known conservationist to reach the awe-inspiring butterfly sanctuary. There, the air shimmered with millions of monarchs, delicate yet determined, filling the trees and sky. Some brushed against her. Others clung to branches like leaves. She had waited a lifetime for this moment.
âYou're just walking through the forest, and then you come across itâitâs incredible,â she said. âThey are everywhere.â
Each year, millions of monarchs make the epic 1,000-5,000-mile journey from as far North as Canada to overwinter in one of only five sanctuaries in North America. Many take off again in spring to return home.
Trip of lifetime

In February, Campbell-Rush received a coveted âWish of a Lifetimeâ grant, designed to âspark hope and joy in the hearts of older adults,â to witness the monarch migration.
To her, monarchs are more than insectsâ they symbolize transformation, tenacity and the magic of nature.

With 50 years of experiences in education, the CU Boulder alumna (MEdu'81) has spent decades raising butterflies and teaching about their conservation. Researchers estimate the population of monarchs in Mexico has decreased by around 80% since the 1990s, according to the the Xerces Society for Invertebrate Conservation.
Campbell-Rushâs love for the orange-and-black creatures and their conservation began early. Her education began at home in New Jersey, where her mother, a physical education teacher and coach, filled their yard with bird feeders and butterfly gardens. Campbell-Rush spent summers chasing monarchs with a net, careful not to harm them. It sparked a lifelong curiosity about their life cycles and migration.

Spreading her wings
Like the monarchs, Campbell-RushâsÌęlife and career have covered a lot of ground. She began teaching kindergarten in New Jersey in the 1970s before moving to Boulder, where she worked in restaurants while pursuing her masterâs in education.
Her restaurant colleagues introduced her to Semester at Sea, and instead of returning to the classroom, she circled the globe by ship in 1983, returning years later as a senior administrator for the program.
âOnce you travel, you just canât stop,â she said. âIf you get the opportunity, you have to do it.â
Beyond her voyages, she taught in London, launched school gardens, raised butterflies with students, and taught lessons with nature as co-teacher.

As a teacher, administrator, professional development leader, and author of seven books, Campbell-Rush continues to mentor new educators with warmth and wisdom.
âThe first thing I tell new teachers is: âThank you for being a teacher,ââ she said. âI also recommend they get three mentors: one mentor that will help with all big questions and another mentor that maybe is in the school already who can give you the behind-the-scenes information.
âThe third mentor is you, because you could go to all the professional development, but you have to consider if itâs something that fits you and your classroom.â
Recently, she was selected as a Fulbright Education Specialist, helping develop civil rights curriculum tied to South Africaâs post-apartheid era and the U.S. Amistad Act.
As well-traveled and accomplished as she is, Campbell-Rushâs sojourn to the butterfly sanctuary in Mexico was, indeed, a trip of a lifetime. One condition of her grant is to pay it forward.
Emerging from the chrysalis
Now, Campbell-Rush lives surrounded by milkweed and memories. This spring, she cared for 74 caterpillars. She also hosts events and inspires neighborhood kids to give milkweed as birthday gifts. She stays connect with former students, mentors new teachers, and visits schools to teach about monarchsâ conservation and resilience.
Resilience means much to Campbell-Rush, a stage 3 breast cancer survivor who taught bald, wearing a custom cap that read âNo Hair Day,â a spin on âBad Hair Day.â The illness taught her to receive help as graciously as she gives it.
âAs women, weâre often givers, and I found it hard to be a receiver,â she said. âBut people get as much from giving as you do from receiving. Thatâs wonderful.â
Just as monarchs return each spring to the gardens where they were raised, Campbell-Rush continues to receive so much inspiration from them as she marvels at natureâs delicate balance. She hopes others will too.
âAs a teacher, I did all kinds of things to bring nature to the kids,â she said. âThey get that wide-eyed look, and you just wait for that. It's so satisfying. Hopefully, in their lives, they're conservationists, who respect wildlife and the world around us.â
