Populations of the iconic monarch butterfly are suffering in both the U.S. and Mexico. Their once large numbers have been decimated in recent years. In 1996 an estimated 1 billion of the butterflies migrated to Mexico; just 35 million made the journey last year. In the U.S. native milkweed, necessary to the insects’ life cycle, has been devastated by herbicides and intensified agriculture. Now the Xerces Society has petitioned the U.S. Fish and Wildlife Service to give the monarch protection under the Endangered Species Act. The FWS has said the petition from the Xerces Society, “presents substantial information indicating that listing may be warranted.” Reuters has more: http://www.reuters.com/article/2014/12/30/us-usa-butterflies-idUSKBN0K800Y20141230
