The monarch was placed on a waitlist until last December, when the agency formally proposed the butterfly's Endangered Species Act listing and unveiled a list of recommended conservation efforts. This began the initial public comment period, which ended March 12.

The Trump administration is reopening public comment on a proposed rule that would list the monarch butterfly as threatened under the Endangered Species Act.

The Monarch Butterfly, Danaus Plexippus, is a very recognizable butterfly. If you have not had the pleasure of observing one, you surely have seen pictures or read about them. The Monarch’s long migration of over three thousand miles to winter habitat is truly a wonder.
