On December 29th, 2014, the U.S. Fish and Wildlife Service announced it would be conducting a status review of the monarch butterfly under the Endangered Species Act (ESA). The Service has reason to believe a listing may be necessary due to considerable evidence from a petition submitted by the Center for Biological Diversity, the Center for Food Safety, the Xerces Society for Invertebrate Conservation and Dr. Lincoln Brower. The petition stated that habitat destruction and loss of milkweed due to pesticide use are two of the most contributing factors to the declining monarch population. Other factors include disease and predation, overutilization for commercial purposes, and lack of existing conservation procedures.

During the summer months, the monarch can be found throughout the United States where milkweed, the species’ host plant, is plentiful. Milkweed provides nutrients to hungry caterpillars as well as space for mature females to lay their eggs. Although an adult monarch may lay up to 500 eggs in its lifetime, it has now been discovered fewer and fewer butterflies make the migration each year.
