To answer the question, we would categorize the information from the excerpt as follows:
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 general decline matched the results of monitoring programs in the United Kingdom, the Netherlands, and Spain.
- The researchers wanted to understand why some species of butterflies were harder-hit than others.
- The team looked to see if related species of butterflies were all doing better or worse and did not find a pattern.
Why this matters:
- The decline of butterfly populations can indicate broader ecological issues affecting insects everywhere.
You would drag the relevant information to the appropriate sections as outlined above.
