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 “how” of restoring habitat is outlined in the consortium’s guidelines for planting prairie. “Where” is the subject of a new peer-reviewed journal article that provides an overview of 20 ISU studies, as well as work by other monarch researchers. 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...

Close your eyes for a moment and imagine a butterfly. My money says the fluttering insect you’re envisioning has black-veined, reddish-orange wings outlined with white specks — the iconic attributes of much loved American monarch butterfly.
