21 July 2022 (IUCN) – “The migratory monarch butterfly (Danaus plexippus plexippus), known for its spectacular annual journey of up to 4,000 kilometers across the Americas, has entered the IUCN Red List of Threatened SpeciesTM as Endangered, threatened by habitat destruction and climate change.
MONARCHS ARE NOT PROTECTED IN THE UNITED STATES
In December 2020, after an extensive status assessment of the monarch butterfly, we (Fish & Wildlife Service) determined that listing the monarch under the Endangered Species Act is warranted but precluded at this time by higher priority listing actions….Our 12-month finding does not protect monarchs under the ESA at this time. We first must propose the monarch for listing as either an endangered or threatened species, gather and analyze public comments and any new information, and using the best available science, make a final decision and publish a final rule. That process is deferred while we work on higher-priority listing actions.
