Some Good News For Monarchs
Spring is the time of the great monarch migration when the butterflies leave their wintering grounds in Mexico and head north to Canada.

In 2013, the number was down to 33 million.

Biologists in the U.S. have been trying to restore the summer habitat of the butterflies by urging the planting of milkweed, which is the primary host plants for monarch butterfly caterpillars.
