The first "Monarch Blitz" is over. 300 people in the U.S. participated by counting eggs, caterpillars, chrysalides, and butterflies. The citizen scientists then submitted their findings to the Monarch Lab at the University of Minnesota.
This first Monarch Blitz included the United States, Mexico, and Canada. Spokeswoman Cora Lund Preston said the results will help researchers find out where Monarchs reproduce, then learn what makes habitat good or bad for them. Their numbers have declined drastically over the past 20 years.
