Monarchs in Illinois

The Great Monarch Migration

It takes 2 or 3 generations of butterflies to migrate from the mountains of Michoacán, Mexico, to the prairies of Illinois in the spring months. By late summer, a ‘super generation’ emerges, equipped to travel an estimated 2,500 miles back to Mexico for overwintering. 

Illinois offers these iconic butterflies the crucial milkweed resources they require for breeding, along with the nectar plants they rely on for subsistence during their migratory journey.

About the Illinois Monarch Project

Over the past 20 years, the eastern monarch population has faced a significant decline in migratory habitat. The Illinois Monarch Project collaborates with public and private partners, in addition to individuals across the state, to protect and enhance existing habitat and establish new habitat that supports monarch butterflies and other pollinators.

With your help, we can reach our goal of adding 150 million new milkweed stems and other nectar resources to the Illinois landscape by 2038.

Join fellow Illinoisans in fostering a culture of conservation that ensures future biodiversity and flourishing pollinator habitat across diverse urban and rural landscapes in Illinois.

Whether you have a few pots on a porch, or acres of sprawling land, every Illinois resident plays a part in the regeneration of this vital pollinator. Every milkweed stem counts. Every nectar-producing wildflower brings the monarch one step closer to survival. Pledge now and make a difference from your own backyard. 

In 2019, over 2,000 Monarch Waystations, or monarch habitats, were registered with Monarch Watch across Illinois – many of which exist in individual home gardens.

The reciprocal relationship between Illinois producers and monarchs is a thing of beauty. Farmers’ futures depend on thriving pollinator populations. While agriculture industry specialists support the future of monarchs through sound science and research, outreach and education practitioners work closely with the agricultural community to share and encourage best practices for conserving, enhancing, and creating monarch habitat.

Agriculture in the Classroom programming provides pollinator specific education to over 106,000 students and nearly 5,000 teachers across Illinois.

Urban, suburban, and rural communities are home to a range of gathering spaces, from corporate campuses and local businesses, to schools, cultural institutions, and parks. From Chicago to Carbondale, communities are hubs of activity that bring people together to fuel the feeding, breeding, and migration of monarchs.

As of 2019, 42 mayors in Illinois have signed onto the Mayor’s Monarch Pledge

From state lands to land trusts and county forest preserves, natural land managers have a long history of protecting and stewarding the unique natural heritage of Illinois. Through the preservation and restoration of native ecosystems, there’s room for these natural protectors to make a lasting impact on this incredible species.

Since 2014, over 3,000 acres of new monarch habitat has been planted in the protected lands network across Illinois, providing an estimated 1.32 million milkweed stems.

Imagine traveling across our country’s highways with no rest stops along the way. Monarch butterflies, one of the great migratory species of our day, face a steep and rapid decline of rest stops along their 2,500 mile journey from Mexico to Illinois. State and local road authorities, electric and gas utilities, and other infrastructure land managers have the opportunity to foster feeding and breeding stations for monarchs along rights-of-way habitat across Illinois.

New mowing guidelines set forth by the Illinois DOT in 2017 resulted in the creation and enhancement of over 80,000 acres of monarch and pollinator habitat throughout the state.
