What they found:
- The overall numbers of butterflies in Ohio have decreased year over year for the past two decades—about 2 percent each year.
- The decline matched the results of monitoring programs in the United Kingdom, the Netherlands, and Spain.
- The team wanted to understand why some species of butterflies were harder-hit than others and why some actually increased their populations over the course of the study.
- They looked to see if related species of butterflies were all doing better or worse, and did not find a pattern.
