Save the Date: Celebrate 10 Years of the Monarch Blitz!
Mark your calendars: the International Monarch Monitoring Blitz is back for its 10th anniversary! From 31 July to 9 August 2026, join the celebration and help search for monarch butterflies and milkweed plants in your area. This is your chance to get outside and make a real difference for one of North America’s most emblematic species!
What is the Monarch Blitz?
The Monarch Blitz is a community science initiative open to anyone in North America. For ten days each summer, everyone is encouraged to step outside, search for monarchs (eggs, caterpillars, chrysalises or butterflies) and milkweed plants, and share their observations on one of several data platforms. Scientists use these observations to better understand how to conserve monarch butterfly populations, which have experienced significant declines over the last few decades. The data is also published in a repository for anyone to consult and download.
10 Years: 10,000 More Participants
We want this to be the most impactful Monarch Blitz yet! Last year, over 9,000 volunteers across North America contributed thousands of observations. For our 10th anniversary, we want to break all records! We’re aiming higher than ever and setting a goal of 19,000 volunteers. That’s 10,000 more people joining the search, and more than twice last year’s number. The only way we’ll reach that goal is with your help!

Whether you’re a longtime monarch enthusiast who has participated for years or you’re just learning about the Monarch Blitz, you can help gather valuable data for monarch conservation, all while enjoying time outdoors.
