"Butterflies are disappearing in Ohio. Here’s what that means for insects everywhere"

For my 11th birthday, I received a perfect, weird, road-trip amusement: a book filled with pictures and descriptions to help kids decode the splatters of insects that smacked into the front of a moving vehicle. Whether that sounds like macabre fun or makes you grumble about keeping the windshield clean, a steep decline in reported bug splatters in recent years should actually make us worried, entomologists and ecologists say.

In a new study published Tuesday in PLOS ONE, a group of researchers analyzed one of the rare data sets that tracks butterfly abundance, taken from 21 years of volunteer surveys in Ohio. They found an average population decline of 2 percent per year, which means that over the course of the study, Ohio lost more than a third of its butterfly population.

Some species of butterflies showed no change in abundance, however, and a few others actually became more common.

“Not everything is going to decline in exactly the same way,” said Corrie Moreau, an entomologist and evolutionary biologist from Cornell University who was not involved in the new research. “But we are seeing, in this study and others, that insects are in a rapid fall.”

Butterflies pollinate flowers, control plant populations by munching on leaves as caterpillars, and provide food for other insects, birds, amphibians, and mammals.

To identify the detail that supports the main idea of the section “Why this matters,” we should focus on the significance of butterflies in the ecosystem and the implications of their decline.

The most relevant choice is:

**"Butterflies pollinate flowers, control plant populations by munching on leaves as caterpillars, and provide food for other insects, birds, amphibians, and mammals."**

This statement underscores the crucial roles butterflies play in the ecosystem, which supports the main idea that their decline has broader implications for the environment. The other options, while they discuss the situation, do not directly emphasize the ecological importance of butterflies as this statement does.
