MINNEAPOLIS (WCCO) — It’s a ritual of spring: Monarch butterflies returning to Minnesota from their winter refuge in Mexico.
But there’s disturbing news south of the border. Scientists report a drop of nearly 60 percent in the number of Monarch butterflies making it to their winter home in Mexico this year — the lowest level since record-keeping began 20 years ago.
It doesn’t surprise a University of Minnesota expert.
“It makes me sad that, despite all these people caring, we still saw this precipitous drop,” said Dr. Karen Oberhauser.
