Monarch Butterflies Endangered

On Thursday, July 21, 2022, the International Union for the Conservation of Nature said migrating monarch butterflies have moved closer to extinction in the past decade – prompting scientists to officially designate them as “endangered."

WASHINGTON — The monarch butterfly fluttered a step closer to extinction Thursday, as scientists put the iconic orange-and-black insect on the endangered list because of its fast dwindling numbers.

"It's just a devastating decline," said Stuart Pimm, an ecologist at Duke University who was not involved in the new listing. "This is one of the most recognizable butterflies in the world."

The International Union for the Conservation of Nature added the migrating monarch butterfly for the first time to its "red list" of threatened species and categorized it as "endangered" — two steps from extinct.
