The Monarch Larva Monitoring Project (MLMP) is a citizen science project involving volunteers from across the United States and Canada in monarch research. It was developed in 1997 by researchers at the University of Minnesota to collect long-term data on larval monarch populations and milkweed habitat. The project focuses on monarch distribution and abundance during the breeding season in North America.

 

As an MLMP volunteer, your contributions will aid in conserving monarchs and their threatened migratory phenomenon, and advance our understanding of butterfly ecology in general. Learn more about broader monarch conservation efforts on the Monarch Joint Venture website. 

 

The MLMP is a collaborative project of the Monarch Joint Venture and University of Wisconsin–Madison Arboretum.
