U.S. officials moved Tuesday to protect the monarch, an iconic orange-and-black butterfly famous for its marathon migration across North America, under the Endangered Species Act.
The U.S. Fish and Wildlife Service’s proposal to designate the tiny migrating butterfly as threatened with extinction could have enormous consequences for landowners across its huge range, which extends across much of the Lower 48 as the monarch makes its epic annual flight from the mountains of Mexico through the United States and into Canada.
