"Disappearing Ohio Butterflies Affects All Insects"

Question

by Vicky Stein

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.
