Mark your calendars: the International Monarch Monitoring Blitz is back for its 10th anniversary! From July 31 to Aug. 9, 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 recognizable species.
What is the Monarch Blitz?
The Monarch Blitz is a community science initiative open to anyone in North America. For 10 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. The data is also published in a repository for anyone to consult and download.
Join the Monarch Blitz!
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. Invite family and friends, go for a peaceful walk by yourself, or even rally a whole neighborhood team!
Participation is simple: just pick a community science program that is right for your region and start reporting your observations. Since you're reading this on the Journey North site, you may already be familiar with our project, and you can submit your observations just as you normally do by clicking here or "report sighting" at the top of the page. At the end of the Blitz, we'll submit the data to our partners to be compiled and published.
Whether you participate once or throughout the 10 days, every observation matters and helps scientists better understand how to conserve this iconic species!
Together, let’s make the 10th anniversary unforgettable. See you outside from July 31 to Aug. 9!
