Join thousands of volunteers in Canada, Mexico and the United States, from July 24 to August 2, 2020 for the 4th annual International Monarch Monitoring Blitz (the Blitz).

With limited ability to do field work due to COVID-19 restrictions, researchers need your observations now more than ever.

“We need a better picture of monarch distribution within its breeding range across North America, so every observation counts. Even if it's from your own backyard.” said Alessandro Dieni, Mission Monarch Coordinator at the Insectarium/Montréal Space for Life.

To take part in the Blitz, submit your data to the Western Monarch and Milkweed Mapper. In addition to entering data through these programs, we encourage you to follow the Blitz on social media using the hashtag #MonarchBlitz!
