MONARCHS MAY BE LISTED AS ENDANGERED SPECIES

 

December 31, 2014 (San Diego’s East County)--Monarch butterflies may warrant protection under the U.S. Endangered Species Act, the U.S. Fish and Wildlife Service states.  Monarch populations have dropped up to 90 percent in the last 20 years due to loss of milkweed plants that the butterflies need to lay their eggs and nourish caterpillars that emerge from cocoons.
