A sweeping new study on one of the most beloved insects, maybe the only truly beloved insect—the butterfly—details its rapid population decline in the United States. The new research, published in the journal Science widens the butterfly net and looks at how more than 500 species have fared over the past 20 years.
Researchers found that many populations are taking a nosedive. What’s causing the downswing, and is there anything we can do?
Host Flora Lichtman talks with two of the study authors, Dr. Elise Zipkin, Red Cedar distinguished professor of quantitative ecology and director of the ecology, evolution and behavior program at Michigan State University; and Dr. Nick Haddad, professor of integrative biology also at Michigan State University in East Lansing, Michigan.
Transcripts for each segment will be available after the show airs on sciencefriday.com.
