At Redgranite Correctional Institution in central Wisconsin, an unusual conservation effort is taking root behind the fence lines: inmates are raising monarch butterflies, nurturing caterpillars into winged migrants before releasing them to continue their long journey south. The program pairs hands-on care with data collection, giving incarcerated participants a way to contribute to wildlife recovery while learning about pollinators and horticulture.
Now in its second year, the initiative has expanded both in participation and scope. What began as an option for men unable to join physical recreation has grown into a seasonal project that supports monarch populations and connects the prison to community conservation partners.

The project, called the Refuge for Growth, Change and Inspiration Monarch Program, runs during the summer months—typically from June through September. Prison staff and program organizers receive monarch caterpillars from the outside breeding center Monarch Watch, then care for them inside a purpose-built lepidopterum at the facility.
Key program elements
- Timing: Seasonal operation to coincide with monarch breeding and migration windows.
- Partners: Monarch Watch supplies caterpillars; the Natural Resources Foundation of Wisconsin assisted with building the enclosure.
- Participants: About 20 inmates currently rotate through the program, which is in its second year.
- Scale: This season the group has overseen roughly 100 caterpillars, up from about 60 the previous year.
What inmates do every day: routine care, data collection, and tagging
The work inside the lepidopterum blends delicate hands-on tasks with simple scientific procedures. Organizers divide participants into teams so responsibilities are clear and routine is maintained.
- Providing fresh milkweed leaves and swapping out plant material as caterpillars eat and grow.
- Monitoring egg and caterpillar stages and recording observations for program records.
- Assisting with chrysalis monitoring and preparing butterflies for release.
- Tagging adult monarchs and logging the tags to contribute to migration tracking and conservation research.
Why tagging and data matter for monarch migration research
Tagged butterflies and field observations collected in programs like this help scientists and conservationists track migration patterns and survival rates. Monarchs make an extraordinary seasonal trip, traveling thousands of miles to overwintering sites in Mexico, and every piece of data helps inform habitat restoration and protection efforts.
While the on-site work is careful and exacting, the goal is simple: produce healthy butterflies ready to continue the migratory cycle and provide useful information to researchers studying population trends.
Grounds improvements and habitat support around the facility
To give newly released monarchs a better chance, correctional department landscapers have installed several monarch-friendly flower beds across the prison grounds. Those plantings supply nectar sources for adults and complement the care the insects receive inside the enclosure.
- Nectar-rich flowers planted to provide foraging opportunities after release.
- Milkweed inclusion to support future local breeding.
- Continuous maintenance by grounds staff to sustain habitat value through the season.
Origins, leadership, and community collaboration
The program was launched in 2025 by Carrie Jahnke as an alternative activity for inmates who couldn’t participate in traditional sports or recreation. The Natural Resources Foundation of Wisconsin played a role in building the indoor enclosure that allows the project to run year by year within the secure environment.
Monarch Watch supplies the caterpillars and educational materials, while program leaders provide instruction on pollinator plants, basic horticulture, and the biology of monarchs so participants understand the broader conservation context of their work.
Voices from inside and outside the program
Participants report that working with monarchs gives them a sense of purpose and a connection to the community beyond the prison walls. One program member recalled childhood memories of raising caterpillars and said being involved again feels meaningful, especially when thinking about the contribution they can make from inside the facility.
Representatives from conservation partners praised the effort as well. Staff from the Natural Resources Foundation of Wisconsin noted that monarch populations have been under pressure, and local initiatives that raise and release healthy butterflies help support broader recovery work.
From chrysalis to flight: preparing monarchs for migration
After emerging from their chrysalises, monarchs spend a brief period inside the lepidopterum to build strength and orient themselves. Typically, caretakers allow butterflies a couple of days to gain weight and condition before opening the enclosure and releasing them onto the prison grounds and into the migration route.
- Observation and final health checks after emergence.
- Attachment of small, numbered tags to aid in tracking.
- Release when weather and condition are favorable—usually after 2 to 3 days of recovery.
