Track Monarch Butterfly Migration


Welcome 2021!

Overwintering News From The Monarch Butterfly Biosphere Reserve: Letters From the Field Continues

Dr. Ellen Sharp and Ms. Estela Romero will provide bi-monthly news on monarch happenings from the monarch sanctuaries in the States of Michoacán and Mexico, in central Mexico. Dr. Sharp will share reports from the Cerro Pelon Monarch Butterfly Sanctuary. Ms. Romero will focus on Sierra Chincua and El Rosario Sanctuaries. During December and January, Ms. Romero will describe her school visits in her weekly blog posts delivering Symbolic Ambassador Butterflies (as part of the Symbolic Migration Project) and other environmental educational programming. Beginning in February, Ms. Romero will return to report on monarch happenings in the Sierra Chincua and El Rosario Sanctuaries until the monarchs take flight for points north.

Weekly monarch migration news updates to resume in February 2021.

Targeted Project: Monitoring Overwintering Monarchs

From January to March 2021, if you live in the Gulf states of Texas, Louisiana, Mississippi, Alabama, and Florida as well as Georgia, South Carolina and North Carolina, please continue to report monarch adult observations. 

Not all monarchs migrate to Mexico. Some breed throughout the winter in the southern U.S., and scattered reports show that other monarchs might overwinter here in a non-reproductive state. Researchers and others studying monarchs are seeking more information to understand why and what it might imply for monarchs, a candidate for listing under the federal Endangered Species Act. For this, they need your help.

Please report your monarch observations to Journey North. Observations include adult monarchs, monarch eggs and monarch larvae. Review our What to Report page here and check out our Instructional Flyer as well.

*This project is a collaborative effort among Journey North, Monarchs Across Georgia, the University of Georgia and the Georgia Department of Natural Resources.
