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. When the researchers compared that rate to other long-term studies, the general decline matched the results of monitoring programs in the United Kingdom, the Netherlands and Spain.

But 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.

On the other hand, they did notice that butterflies more commonly found in southern Ohio tended to do better than the more northern butterflies, perhaps because they are already better suited to respond to the planet’s warming climate.

“There are some weird cases too,” Wepprich said. “The wild indigo dusky-wing,” a brown butterfly with marbled wings that measure about an inch and a half across, “is doing really well in Ohio because a plant it eats is used as erosion control on construction sites. It’s three times more numerous now than it was 20 years ago.”

That’s intriguing, he said, because it demonstrates the massive—and rapid—effect that humans can have on insects with the dedication of relatively minor resources. It’s one note of optimism amidst a general trend of bad news.

Why this matters



Butterflies pollinate flowers, control plant populations by munching on leaves as caterpillars, and provide food for other insects, birds, amphibians and mammals. Their decline could have cascading effects on forests, prairies and even backyards across North America—vital wild habitats for an abundance of living things.

But butterflies also act as big, flashy beautiful warning signs for environmental change. “I think for most of us entomologists, butterfly data are being taken as a proverbial canary in the coal mine,” Shapiro said.

The decline of Ohio’s butterflies has been captured through statistics and recorded data rather than anecdotes, but the scientific literature abounds with anecdotes as well. One recent article from experienced researchers Daniel Janzen and Winnie Hallwachs, a pair who have studied tropical ecology in Mexico and Central America for half a century, warns that insects around the world are in the midst of a “gradual and very visible decline.”

The solution to a worldwide insect decline won’t be simple. “If it was just one thing, we would know how to fix it,” Moreau said. “But I think of the situation as, like, death by a thousand cuts.”

Insect decline can affect habitats. There was a difference in how northern and southern Ohio butterflies were doing. Changes in butterflies can signal larger environmental changes. The data from Ohio matched studies from other countries.
