A country without Butterflies: America’s butterflies are disappearing at ‘catastrophic’ rate, study says Butterflies are disappearing in the United States. All kinds of them. With a speed scientists call alarming. America’s butterflies are disappearing because of insecticides, climate change and habitat loss, with the number of the winged beauties down 22% since 2000, a new study finds.

When the Iowa Monarch Conservation Consortium was formed in US seven years ago, Iowa State University researchers faced two big questions about reestablishing the milkweed and other wildflowers needed for the iconic butterfly’s survival: How can habitat be restored and where should it be located?

The paper, published in Bioscience earlier this month, synthesizes years of research that includes field observations, laboratory experiments and simulation modeling. The findings are largely optimistic. FILE PHOTO: In this March 28, 2018, file p...

Unfortunately, the species, which populates many childhood memories, is in trouble. The migrating monarch butterfly was added last week to the “red list” of threatened species and categorized as “endangered” for the first time by the International Union for the Conservation of Nature. That’s two steps from extinct in the wild. FILE PHOTO: Monarch butterflies land on branches at Monarch Grove Sanctuary in Pacific Grove, Calif., Wednesday, Nov. 10, 2021.
