"Limits Sought on Weed Killer Glyphosate To Help Monarch Butterflies"

"With monarch butterfly populations rapidly dwindling, a conservation organization on Monday asked the U.S. Environmental Protection Agency to implement tougher rules for the weed killer glyphosate — first marketed under the brand name Roundup — to save America’s most beloved insect from further decline."

"In a petition, the Natural Resources Defense Council argued that current uses of glyphosate are wiping out milkweed, the only plant upon which monarch caterpillars feed. The loss of milkweed is having a devastating effect on the life cycles of the large, fragile orange-and-black butterflies, which migrate through the United States, Canada and Mexico.

It takes several generations of the insect scientists know as Danaus plexippus to make the round trip because each monarch lives only a few weeks in the summer."
