Whether that soundslike macabre fun or makes you grumble aboutkeeping the windshield clean, a steep decline inreported bug splatters in recent years shouldactually make us worried, entomologists andecologists say.
In a new study published Tuesday in

, a group of researchers analyzed one ofthe rare data sets that tracks butterflyabundance, taken from 21 years of volunteersurveys in Ohio. They found an averagepopulation decline of 2 percent per year, whichmeans that over the course of the study, Ohiolost more than a third of its butterfly population.
Some species of butterflies showed no changein abundance, however, and a few othersactually became more common.
“Not everything is going to decline in exactly thesame way,” said Corrie Moreau, anentomologist and evolutionary biologist fromCornell University who was not involved in thenew research. “But we are seeing, in this study
